Two new imidazole alkaloids (lepidiline A and lepidiline B) have been isolated from a root extract of Lepidium meyenii with the common name Maca and identified as 1,3-dibenzyl-4,5-dimethylimidazolium chloride (1) and 1,3-dibenzyl-2,4,5-trimethylimidazolium chloride (2), respectively. The structures of these two new compounds were determined by spectroscopic methods, as well as single-crystal X-ray diffraction performed on compound 1.

This study was a 12-week double blind placebo-controlled, randomized, parallel trial in which active treatment with different doses of Maca Gelatinizada was compared with placebo. The study aimed to demonstrate if effect of Maca on subjective report of sexual desire was because of effect on mood or serum testosterone levels. Men aged 21-56 years received Maca in one of two doses: 1,500 mg or 3,000 mg or placebo. Self-perception on sexual desire, score for Hamilton test for depression, and Hamilton test for anxiety were measured at 4, 8 and 12 weeks of treatment. An improvement in sexual desire was observed with Maca since 8 weeks of treatment. Serum testosterone and oestradiol levels were not different in men treated with Maca and in those treated with placebo (P:NS). Logistic regression analysis showed that Maca has an independent effect on sexual desire at 8 and 12 weeks of treatment, and this effect is not because of changes in either Hamilton scores for depression or anxiety or serum testosterone and oestradiol levels. In conclusion, treatment with Maca improved sexual desire.

Maca is a cruciferous plant native of the central Andean of Peru (above 4000 m.a.s.n.). It is known that MACA is used since 2000 years ago as nourisment and medicine. As an aphrodisiac for both men and women (those seeking heightened sexual prowess). Native Peruvians use MACA to increase energy, stamina and endurance (great for athletes), also to promote mental clarity, male impotence and female hormonal imbalances.

It becomes the most effective naturist medicine of Peru, due to its high contents of proteins, essential vitamins, amino acids, high quality carbohydrates and minerals. It is a revitalizer ideal as natural dietetic component for children and adults. Important geriatric action.
