“…The benzyl glucosinolate content of Xinjiang maca is 1.24 mg/g maca, which also means that the proportion of glucosinolate is 0.124% in maca. This is lower than the result of 0.2% reported by Li et al [5].…”

“…), a biennial herbaceous plant of the family brassicae, which is cultivated mainly in the central Andes of Peru at elevations of 3500-4500 m above sea level, has been used as both a food and a traditional medicine in the region for over 2000 years [1]. Domestic and foreign experts researched on the nutritional compositions and secondary metabolites of maca, finding that it not only contains rich protein, amino acids, fat, and minerals ion [2] but also contains a variety of secondary metabolites: maca ene, alkaloid (including maca amide), glucosinolate, and other components [3][4][5]. These secondary metabolites are considered closely related to the health effects of maca.…”

Environment would affect the nutritional composition of maca, especially its secondary metabolite. The chemical compositions and function of Xinjiang maca were not very clear. The chemical compositions and bioactivity of Xinjiang maca were determined. A mouse model was also used to evaluate the antifatigue activity of Xinjiang maca as a forced swimming test was performed and certain biochemical parameters related were estimated. The results show that the Xinjiang maca is rich in protein content and amino acids, especially branched chain amino acids such as Valine and Isoleucine related to the effect of antifatigue. It also has considerable minerals ions such as Ca and Mg. Besides, bioactive ingredients such as maca amide, glucosinolate, and alkaloid of Xinjiang maca are similar to those of maca from other areas, which qualify the biological value of Xinjiang maca. The results of mice model suggest that maca has a dose-dependent antifatigue activity by decreasing blood lactic acid, as well as increasing liver glycogen content and the forced swimming time.

Lepidium meyenii (Maca) is a Peruvian hypocotyl that grows exclusively between 4000 and 4500 m in the central Andes. Maca is traditionally employed in the Andean region for its supposed fertility-enhancing properties.The aim of this study was to test the hypothesis that Maca can prevent high altitude-induced testicular disturbances. Adult male rats were exposed for 21 days to an altitude of 4340 m and treated with vehicle or aqueous extract of Maca (666·6 mg/day). The lengths of the stages of the seminiferous epithelium and epididymal sperm counts were obtained at 0, 7, 14 and 21 days of exposure. The stages of the seminiferous tubules were assessed by transillumination. A dose-response study was also performed at sea level to determine the effect of Maca given to male rats at doses of 0, 6·6, 66·6 and 666·6 mg/day for 7 days on body weight, seminiferous tubule stages and epididymal sperm count. The length of stage VIII and the epididymal sperm count were increased in a dosedependent manner in Maca-treated rats but treatment reduced the length of stage I. At the highest dose, sperm count increased 1·58 times, the length of stage VIII increased 2·4 times and the length of stage I was reduced 0·48 times compared with the value at dose 0. Exposure to high altitude resulted in a reduction in epididymal sperm count after 7 days and lower values were maintained up to 21 days. Altitude reduced spermiation (stage VIII) to half and the onset of spermatogenesis (stages IX-XI) to a quarter on days 7 and 14 but treatment with Maca (666·6 mg/day) prevented these changes. Data on transillumination and epididymal sperm count in the Macatreated group exposed to high altitude were similar to those obtained at sea level. Maca increased the sperm count on day 21 of exposure to high altitude to values similar (1095·25 20·41 10 6 sperm, means S.E.M.) to those obtained in the Maca-treated group at sea level (1132·30 172·95 10 6 sperm). Furthermore, in the Maca-treated group exposed for 21 days to high altitude, epididymal sperm count was higher than in the nontreated group at sea level (690·49 43·67 10 6 sperm). In conclusion, treatment of rats with Maca at high altitude prevented high altitude-induced spermatogenic disruption.

“…es la única Brassicaceae domesticada de los andes peruanos (3700 -4500 m de altitud). La raíz es usada para el consumo humano por su gran valor nutricional desde tiempos precolombinos; además contiene metabolitos secundarios que le confieren propiedades medicinales tales como la estimulación en la producción de folículos ováricos en ratas (Chacón, 1961); efecto sobre la espermatogénesis de ratas (Gonzales et al, 2001) esta propiedad podría deberse a la presencia de isotiocianatos biológicamente activos: benzil-isotiocianato y p-metoxibenzil isotiocianato (Li et al, 2001), además se le atribuye efecto antioxidante (Sandoval et al, 2002).…”

Actividad leishmanicida de los extractos metanólicos de cuatro ecotipos de Lepidium peruvianum, Chacón (Brassicaceae)

ResumenEl tratamiento clásico de la leishmaniosis cutánea consiste en la inyección de 15-20 ampollas de Glucantine lo que ocasiona efectos secundarios, este hecho justifica la búsqueda de nuevos medicamentos motivando la presente investigación. El objetivo fue evaluar in vitro la actividad leishmanicida de los extractos metanólicos (EM) de los ecotipos blanco, rojo, morado y negro de Lepidium peruvianum, Chacón (también conocida como Lepidium meyenii Walp.), sobre el crecimiento de Leishmania braziliensis peruviana. Los promastigotes alcanzaron la fase de crecimiento exponencial al quinto día de cultivo a 27 ºC en el medio bifásico Columbia, suplementado con 15% de sangre desfibrinada de carnero, en ese momento se enfrentaron, por separado, con los EM a concentraciones de 50, 100, 200 y 400 μg/ml. Los recuentos se hicieron diariamente con cámara Neubauer. La máxima disminución de promastigotes se produjo al segundo día de enfrentamiento para el ecotipo morado (17,41% de viabilidad) empleando 400 μg/ml. El efecto leishmanicida estaría relacionado con los alcaloides imidazólicos presentes en el EM. Se concluye que al segundo día de enfrentamiento con el EM, el ecotipo morado presenta la mayor actividad leishmanicida seguido del ecotipo blanco.Palabras clave: Leishmania braziliensis peruviana, Lepidium peruvianum; Lepidium meyenii, actividad leishmanicida, plantas medicinales peruanas, ecotipos de Maca. AbstractThe classic treatment of the cutaneous leishmaniosis consists on the injection of 15-20 ampoule of Glucantine what causes serious secondary effects. This fact justifies the search of new medications what motivated the present investigation. The objective was to evaluate the leishmanicidal activity of the methanolic extracts (ME) of the white, red, purple and black ecotypes of Lepidium peruvianum Chacón (at present Lepidium meyenii Walp.) about the growth of Leishmania braziliensis peruviana in vitro. The promastigotes reached the logarithmic phase to the fifth day of cultivation at 27 ºC in the two-phase Columbia medium with 15% of defibrinated sheep blood and they faced, for separate, with the ME to concentrations of 50, 100, 200 and 400 μg/ml. The recounts were made daily with camera Neubauer. The maximum decrease of promastigotes (17.41% of viability) took place to the second day for the purple ecotype with the concentration of 400 μg/ml. The leishmanicidal effect would be related with the imidazolic alkaloids, glucosinolates, flavonoids, tannins and saponines present in the ME. The conclusion is that only ME of the white and purple ecotypes presents leishmanicidal activity, at second day of culture.
