Hace varios siglos, en una remota e inaccesible región montañosa del sur de Siberia, los médicos primitivos descubrieron una raíz que aumentaba la longevidad y energía, a la que llamaron "raíz del Maral", debido a que una variedad de venado local -el Maral- desenterraba e ingería estas raíces durante la época de apareamiento, cuando los machos pelean entre sí para obtener el control de la manada y de las hembras en celo, para reponer sus gastadas energías.
A raíz de ello, comenzaron a utilizar la planta para incrementar su potencial energético y retardar el envejecimiento, elevando el promedio de vida en la zona a 100 años. Estos médicos primitivos emplearon el extracto de la raíz del Maral contra el cansancio físico, luego de enfermedades agotadoras, para contrarrestar la debilidad senil y la disminución de las funciones sexuales. Sin embargo, solo unas pocas personas conocían los lugares donde crece la planta y este conocimiento fue pasado de una generación a otra.

PRESIONE LA BOTELLA PARA CONOCER LA PLANTA |
| |
En el año de 1942, en plena Segunda Guerra Mundial, Rusia necesitó medicamentos que contribuyeran a curar las heridas y restauraran la energía perdida de sus soldados, por lo que enviaron expediciones científicas a Siberia, donde circulaban rumores acerca de la existencia de plantas con potencial curativo. Estas expediciones encontraron a la raíz del Maral (Leuzea carthamoides, llamada también Rhaponticum carthamoides) en los bosques montañosos y praderas de un territorio limitado en la remota región de Altay, Kusnetzki Ala-Tau y Sayani. Dieron a conocer la descripción botánica detallada de la planta y enviaron los primeros fardos con raíces de Leuzea a diversos centros de investigación de la Unión Soviética , para su estudio científico.
Luego de extensos estudios secretos, el ejército soviético incluyó los extractos de Leuzea en su arsenal de medicamentos para el campo de batalla, con el objeto de acortar el tiempo de reacción de los soldados bajo la presión del combate.
Después de la guerra continuaron las investigaciones, y en 1965 se aisló el principal principio activo de la planta, la Ecdisterona. El extracto de Leuzea se convirtió en favorito de los políticos del Kremlin y se utilizó en el programa espacial soviético. Debido a las aplicaciones militares de estas investigaciones, la mayoría de los resultados fueron considerados secreto militar y no se publicaron en las revistas científicas.
Años más tarde, un selecto grupo de médicos y bioquímicos del Centro Anti-Dopping del Comité Olímpico Ruso, descubrió que la Leuzea carthamoides aumenta en gran forma la síntesis proteica. Con la caída del muro de Berlín en 1989 y la apertura de la medicina soviética al resto del mundo, el conocimiento de las propiedades de esta planta fue del dominio científico internacional. En 1995, luego de numerosos estudios en atletas rusos, el extracto de Leuzea se convirtió en el adaptógeno oficial del equipo olímpico soviético.
Desde 1984, la Leuzea carthamoides está incluida en la Farmacopea Rusa y forma parte del arsenal terapéutico soviético. En vista de su limitada área de distribución y a las dificultades para su cultivo y regeneración, esta planta es considerada como una especie rara y en peligro de extinción, por lo que el gobierno de Rusia ha limitado su exportación fuera de ese país. |

Principios activos
Las raíces de Leuzea carthamoides contienen una variedad de compuestos fisiológicamente activos. Son especialmente ricas en flavonoides (kaempferol) y lignanos de gran potencia antioxidante y estimulante en general. También contienen ácidos orgánicos que afectan procesos metabólicos específicos como, por ejemplo, el ácido tartárico, que reduce la conversión de carbohidratos a grasas.
Estudios farmacológicos y bioquímicos han demostrado que 3 compuestos esteroideos, aislados por cromatografía, muestran la mayor actividad estimulante. Dos de estos compuestos han sido identificados con la ayuda de la espectrometría de masa y resonancia nuclear magnética. Estos compuestos son la Ecdisterona , la Inocosterona y la dehydroamarasterona B. Estas dos sustancias pertenecen a la categoría de esteroles polihidroxilados del grupo de las ecdisonas y son los responsables de la actividad anabólica de la planta. |
 |
| |
Aunque los componentes individuales de la Leuzea muestran gran actividad farmacológica, diversos estudios han demostrado que el uso de todos los componentes de la planta ofrece un efecto sinergístico mayor que la suma de la sus compuestos individuales. |
|
|
Propiedades de la Leuzea carthamoides:
• Induce la síntesis proteica.
Posee actividad anabólica, activando la síntesis proteica, especialmente en los tejidos musculares, por lo tanto, aumenta la masa muscular. Además, estimula la síntesis del ARN (ácido ribonucleico) en las células hepáticas. La síntesis proteica resulta de especial importancia durante los períodos de estrés como, por ejemplo, las intervenciones quirúrgicas, pero también en las fases catabólicas de la vida, como durante el envejecimiento. La Ecdisterona activa el anabolismo, retarda el catabolismo proteico y puede detenerlo parcialmente.
• Activa la síntesis de los siguientes catalizadores bioquímicos:
- Enzimas que participan en los procesos de generación energética celular: glucosa deshidrogenasa, fosfatasa ácida, glutarato decarboxilasa, malato deshidrogenasa, succinato deshidrogenasa.
- Una enzima responsable de la síntesis del ácido gama-amino-butírico (GABA) un neurotransmisor inhibitorio cerebral: la glutamato decarboxilasa.
- Una enzima que participa en el metabolismo de la tirosina y adrenalina: la dopa-decarboxilasa
- Una enzima que participa en la regulación de los impulsos nerviosos en el sistema colinérgico: la acetilcolin-esterasa cerebral
- Un sistema enzimático que participa en la fosforilación de las proteínas: el sistema de la AMP-cíclico-proteínquinasa.
• Antioxidante
La Ecdisterona, lignanos y flavonoides de Leuzea ofrecen un efecto protector contra las toxinas que producen daño a la cromatina del núcleo celular, como resultado de las reacciones de los radicales libres en las células hepáticas, por lo tanto contribuyen a la eliminación de radicales libres. Además, induce la síntesis de la catalasa, que interviene en la eliminación del peróxido de hidrógeno que se produce en exceso como resultado del estrés oxidativo.
• Antianémico
Estimula la síntesis de hemoglobina y la eritropoiesis, logrando una rápida regeneración eritrocitaria.
• Mejora la circulación sanguínea muscular y cerebral, antes, durante y después de los esfuerzos físicos y durante la reacción de estrés.
• Fortalece el sistema inmune
Incrementa la resistencia inespecífica al estrés, mejorando la inmunidad celular y humoral inespecíficas. Por ello, contribuye a prevenir la gripe y otras infecciones virales comunes.
• Previene el desarrollo de hipoglicemia durante los períodos de estrés
• Regula el eje adreno-corticotrópico
Cuando la secreción hormonal suprarrenal se encuentra disminuida, debido a la sobre-estimulación crónica que ejerce el estrés de larga evolución como ocurre en la condición de agotamiento, la insuficiencia de estas hormonas puede ser suplida por la ecdisterona. Este principio activo no es un esteroide, es una fitohormona que puede ser calificada como precursor esteroideo. El organismo no prefiere ni reconoce este precursor, cuando sus hormonas endógenas están presentes, pero, ante su disminución o ausencia, lo puede utilizar de forma similar. Por ejemplo, durante el ejercicio físico extremo, los niveles de testosterona disminuyen en gran forma. La ecdisterona se convierte en un sustituto efectivo, ofreciendo una actividad anabólica similar a la de la testosterona mejorando la capacidad de adaptación al estrés.
• Mejora la contractilidad miocárdica y disminuye las arritmias
• Incrementa la resistencia a la falta de oxigenación
• Sistema Nervioso
Contribuye a mejorar los trastornos del sueño, depresión, astenia, eficiencia mental, disminuye la fatiga mejorando la concentración mental y el tiempo de reacción neurológica, al mismo tiempo que restaura la capacidad de trabajo mental.
• Sistema reproductor
En los hombres, aumenta los niveles de testosterona, la viabilidad y movilidad de los espermatozoides y el interés sexual. En las mujeres, contribuye a evitar la amenorrea por estrés o entrenamiento atlético.
El mecanismo de acción de la Ecdisterona probablemente es similar al de las hormonas esteroideas humanas, sin sus efectos secundarios.

Contraindicaciones:
• Hipersensibilidad a alguno de sus componentes.
• Hipertensión arterial incontrolada o enfermedades cardiovasculares severas.
• No debe ser administrado durante el embarazo o cuando se sospeche su existencia.
• No suministrar a niños.
|
| |
|
| Reacciones adversas:
Uno de los más importantes aspectos de Leuzea es su carencia total de toxicidad, incluso cuando se utiliza por períodos prolongados. Considerando que miles de personas han utilizado esta fórmula, es sorprendente la ausencia de reportes sobre molestias gastrointestinales, diarrea o reacciones alérgicas.
El seguimiento a largo plazo no ha demostrado ningún efecto secundario adverso. A pesar de su efecto anabólico, no interfiere con el balance de los andrógenos y no causa los signos de androgenización que se observan con los anabólicos sintéticos.
La toxicidad debida a la sobredosis de Leuzea es prácticamente desconocida. La presión arterial, parámetros hemáticos o hepáticos no se modifican con su uso.
Algunas personas pueden experimentar insomnio, en cuyo caso la dosis puede ser reducida.

[Protective effect of ecdysterone against sodium arsenite-induced endothelial cell apoptosis]
Wu X, Wang WJ. Department of Cardiothoracic Surgery, Nanfang Hospital , First Military Medical University , Guangzhou 510515, China .
OBJECTIVE: To study whether ecdysterone (EDS) inhibits apoptosis of endothelial cells. METHODS: In the model of sodium arsenite (Ars)-induced endothelial cell apoptosis, the effect of EDS at varied dosages (50, 200, 800 mg/L) on cell apoptosis was observed by measuring the number of apoptotic endothelial cells, intracellular adhesion molecule-1 (ICAM-1) and the oxidative state (OS). RESULTS: Ars at the dosages of 40, 80, 160 mmol/L was capable of causing an increase in the number of apoptotic endothelial cells in vitro, and 160 mmol/L Ars exhibited the strongest effect. EDS was shown to exert influence on the apoptosis-inducing effect of Ars, which decreased the apoptotic cell number at the dosage of 50 and 200 mg/L, but a contrary effect occurred while at the dosage of 800 mg/L. Meanwhile EDS (50, 200 mg/L) inhibited the increase of ICAM-1 expression in the endothelial cells in response to Ars, but failed to significantly elevate the low OS induced by Ars (P>0.05). CONCLUSION: Ars induces endothelial cell apoptosis dose-dependently, and in a similar manner, EDS produces influence on the apoptosis-inducing action of Ars. EDS (50, 200 mg/L) may decrease the apoptotic endothelial cell number and lower the Ars-induced increase of ICAM-1 expression, demonstrating its protective effect on the endothelial cells against apoptosis. |

[The effects of ecdysterone on the apoptosis and necrosis of cultured HUVEC induced by endotoxin]
Shi F, Zhang J, Zhang M. Institute of Burn Research, Southwestern Hospital, The Third Military Medical University , Chongqing P.R. China.
OBJECTIVE: To study the protective effects of ecdysterone (EDS) on the apoptosis and necrosis of cultured HUVEC induced by endotoxin. METHODS: HUVEC was cultured in vitro. Apoptosis and necrosis of HUVEC were induced by LPS, and EDS was added in test specimen. Apoptosis was determined by means of flow cytometry and fluorescent microscopy. RESULTS: There was relatively less number of apoptosis and necrosis of in vitro cultured normal HUVEC than that after LPS stimulation, whereas apoptosis dominated over necrosis. After EDS was added to the culture of HUVEC, cell apoptosis and necrosis decreased simultaneously. CONCLUSION: EDS might exert protective effects on cultured HUVEC against apoptosis and necrosis induced by LPS. |

Study of excretion of ecdysterone in human urine.
Tsits impikou C, Tsamis GD, Siskos PA. Doping Control Laboratory of Athens , Olympic Athletic Center of Athens , Maroussi, Greee.
|
| A study of excretion in human urine of ecdysterone, which is the active component of several over-the-counter supplements such as "Ecdysten", reportedly used by athletes, is presented. The study was performed after oral administration of 20 mg of ecdysterone. The collected urine samples were prepared using the standard screening extraction procedure for the free and conjugated fraction of anabolic steroids, and analyzed by gas chromatography (GC) coupled with quadrupole mass spectrometry (MS) and also with high-resolution mass spectrometry (HRMS). Two ecdysterone metabolites were identified and detected along with unchanged ecdysterone. Accurate mass measurements were made for diagnostic ions, including the molecular ion of the main metabolite of ecdysterone, deoxyecdysone , which, to our knowledge, has not previously been reported in the literature. These accurate mass measurements support the proposed fragmentation scheme. |

Adaptogenic properties of six rasayana herbs used in Ayurvedic medicine.
Rege NN, Thatte UM, Dahanukar SA. Ayurveda Research Centre, Department of Pharmacology and Therapeutics, Seth GS Medical College, Mumbai , India . |
Plants from all over the world such as Eleutherococcus senticosus, Panax ginseng, Raponticum carthamoides , Rhodiola rosea, Withania somnifera and Ocimum sanctum have been extensively evaluated for their adaptogenic potential. However, none of them has been successfully introduced as an adaptogen in the clinic. This paper discusses some of the problems in evaluation of adaptogens which have precluded their inclusion as clinically useful drugs. We further discuss our results with six rasayana plants from Ayurveda, which were studied for their adaptogenic potential. The whole, aqueous, standardized extracts of selected plants (Tinospora cordifolia, Asparagus racemosus, Emblica officinalis, Withania somnifera, Piper longum and Terminalia chebula) were administered orally to experimental animals, in a dose extrapolated from the human dose, following which they were exposed to a variety of biological, physical and chemical stressors. These plants were found to offer protection against these stressors , as judged by using markers of stress responses and objective parameters for stress manifestations. Using a model of cisplatin induced alterations in gastrointestinal motility, the ability of these plants to exert a normalizing effect, irrespective of direction of pathological change was tested. All the plants reversed the effects of cisplatin on gastric emptying , while Tinospora cordifolia and Asparagus racemosus also normalized cisplatin induced intestinal hypermotility. Tinospora cordifolia was also tested for its ability to modulate the changes occurring in the phagocytic activity of peritoneal macrophages after exposure of rats to either carbon tetrachloride or horse serum. It was found to normalize the phagocytic function irrespective to the direction of change, complying to the definition of an adaptogen. All the plant drugs were found to be safe in both acute and subacute toxicity studies. Studies on the mechanisms of action of the plants revealed that they all produced immunostimulation. The protection offered by Tinospora cordifolia against stress induced gastric mucosal damage was lost if macrophage activity was blocked. Emblica officinalis strengthened the defence mechanisms against free radical damage induced during stress. The effect of Emblica officinalis appeared to depend on the ability of target tissues to synthesize prostaglandins. Recent data obtained with Tinospora cordifolia suggest that it may induce genotypic adaptation, further opening the arena for more research and experimentation.

[The search for new anti-ulcer agents from plants in Siberia and the Far East ]
Amosova EN, Zueva EP, Razina TG. Institute of Pharmacology , Tomsk Research Center , Siberian Branch of Russian Academy of Medical Sciences, Russia . |
| Screening tests on mice with the use of a model of neurogenic damage to the stomach revealed antiulcerative activity in extracts of Amoor cork tree, Pacific Bergenia, Lespedeza dichromatic, Leuzea carthamoides , sea-buckthorn, common aspen, Manchurian nuts, Serratula coronarius, and Scutellaria baicalensis. It was proved that an extract of aspen cork produces a marked antiulcerative effect on being administered to animals with "acute" ulcers and in treatment of chronic peptic ulcer. The study of various drug forms of Serratula coronarius extracts (prepared from the bark and the bark and shoots) in experiments on mice (neurogenic ulcer) and rats (Aspirin ulcer) revealed the most marked gastroprotective effect of oil extracts of bark and shoots. A high antiulcerogenic activity of extracts prepared from grass and roots of Scutellaria baicalensis was demonstrated. |

[Phytotherapeutic aspects of diseases of the circulatory system. 6. Leuzea carthamoides (WILLD.) DC: the status of research and possible use of the taxon]
Opletal L, Sovova M, Dittrich M. Farmaceuticka fakulta Univerzity Karlovy, Hradec Kralove .
Leuzea carthamoides (WILLD.) DC., Asteraceae, has become an important taxon usable in human practice and animal production in recent years. Originally an endemic plant of southern Siberia , now it is widely grown not only in the Union of Independent States, once the original region of introduction, but also in central and eastern Europe. The principal constituents of the whole plant are ecdysteroids (5 beta-cholest-6-on-7-ene derivatives) and flavonoids. In addition, the aerial part contains sesquiterpenic lactones of the guajanolide type, and the roots contain polyines (on the thiophene base). The present paper comprehensively discusses the occurrence, content and biological activity of these substances, the preparations manufactured from the plant, their use in therapeutic practice, food manufacture and animal production in the world and the Czech Republic . The plant has certainly become a taxon with prospects in the Czech Republic , particularly as the source of 20-hydroxyecdysone, which is getting into the limelight in the world.

[The results of experimental study of phytoecdysteroids as erythropoiesis stimulators in laboratory animals]
Syrov VN, Nasyrova SS, Khushbaktova ZA. |
| Phytoecdysteroids alpha-ecdysone, 2-desoxyecdysterone, ecdysterone, sileneoside A, and turkesterone isolated from Rhaponticum carthamoides (Willd.) IIjin, Silene brahuica Boiss and Ajuga turkestanica (Rgl.) Repeated administration of brig increased the content of erythrocytes and hemoglobin in the blood of intact rats. The most active of them--ecdysterone , sileneoside A, and, particularly turkesterone, cause also a marked effect on red blood regeneration in hemotoxic phenylhydrazine anemia. In its capacity for simulating erythropoiesis turkesterone resembles the well-known steroidal anabolic drug nerobol. |

Insect hormones in vertebrates: anabolic effects of 20-hydroxyecdysone in Japanese quail.
Slama K, Koudela K, Tenora J. Institute of Entomology, Czech Academy of Sciences, Praha, Czech Republic. |
| Ecdysteroids are hormones controlling cell proliferation, growth and the developmental cycles of insects and other invertebrates. They are occasionally present in various unrelated plants for no apparent reason; no phytohormonal function has yet been identified. In certain cases, ecdysteroids are accumulated to high levels in leaves, roots or seeds. Some ecdysteroid-containing plants have been known as medicinal plants for centuries. One of them, Leuzea carthamoides Iljin (Asteraceae), growing in Central Asia , contains 0.4% ecdysteroid in dry roots and 2% in seeds. A pharmacological preparation from this plant, "Ecdisten', is already available as a commercial preparation for its anabolic, tonic and other effects, for medical use (review). It remained problematic, however, whether ecdysteroids were truly responsible for these effects, because Leuzea contains a number of other biologically active compounds in addition to ecdysteroids. We extracted and purified ecdysteroids from the seeds of Leuzea. With 6 g of 96% 20-hydroxyecdysone (20E), we made a large-scale feeding assay with Japanese quail to find out whether ecdysteroid alone could duplicate the anabolic effects of the seeds. We found that the 96% ecdysteroid increased the mass of the developing quails in a dose-dependent manner, with the rate of increase proportional to the ecdysteroid content in the seeds; there was a 115% increase in living mass with 100 mg kg-1 of pure 20E compared with 109.5% increase with 100-180 mg kg-1 20E equivalents in the seeds. We conclude that the plethora of growth-promoting, vitamin-like effects induced in vertebrates by Leuzea is mediated by ecdysteroids. |

Effects of extract from Rhapontcum carthamoides (Willd) Iljin (Leuzea) on learning and memory in rats.
Mosharrof AH. Institute of Physiology , Bulgarian Academy of Sciences.
The effects of extract from Rhaponticum carthamoides (Willd) Ijin (Leuzea) on the processes of learning and memory in rats were investigated. R. carthamoides was administered orally in doses of 0.25, 0.5 and 2.5 g/kg body weight for 10 days prior to the training session. Using the maze-training method of active avoidance with punitive reinforcement, R. carthamoides improved the learning and memory indices to one degree or another depending on the dose applied. Using the "staircase-maze" method of training with food reinforcement, the low dose of R. carthamoides had no effect, while the high dose deteriorated learning. Using the method of step-through passive avoidance with punitive reinforcement, all three doses of R. carthamoides did not affect substantially the memory indices. R. carthamoides in a dose of 0.5 g/kg, administered orally for 10 days prior to the training, completely eliminated the scopolamine-induced memory impairment. |

[Anabolic activity of phytoecdysone-ecdysterone isolated from Rhaponticum carthamoides (Willd.) Iljin]
Syrov VN, Kurmukov AG. |
| Introduction of phytiexdizone-exdisterone (0.5 mg/100 g) to rats for 7 days is shown to be attended by an accelerated body weight gain and also by a rising weight of the liver, heart, kidneys and musculus tibialis anterior. In these organs the total amount of protein increases. All of the above-stated changes are more marked when the substance is given to growing rats (70-- 80 g ). In experiments on castrated sexually immature rats the androgenic action of exdisterone, unlike that of methandrostenolone, is not demonstrable. |

High-performance liquid chromatographic analysis and separation of N-feruloylserotonin isomers.
Pavlik M, Laudova V, Gruner K. Institute of Organic Chemistry and Biochemistry, Academy of Sciences of the Czech Republic, Prague. |
| The N-feruloylserotonin containing fraction was isolated from seeds of Leuzea carthamoides (Willd.) DC by solvent extraction followed by column chromatography on silica gel or on Sephadex LH-20. Nuclear magnetic resonance spectroscopic analysis of the isolated fraction showed the presence of four structurally related compounds. These compounds were identified as four isomers of N-feruloylserotonin: N-(Z)-feruloylserotonin, N-(Z)-isoferuloylserotonin, N-(E)-feruloylserotonin and N-(E)-isoferuloylserotonin. They were analyzed by HPLC on Separon SGX C18, Separon SGX and Separon SGX phenyl, using various mobile phases. Separon SGX phenyl phase was found the most efficient for a rapid analysis and for the final separation of the N-feruloylserotonin isomers. |
