New alkamides from maca (Lepidium meyenii).
Maca (Lepidium meyenii) has been used as a food in Peru for thousands of years. More recently a wide array of commercial maca products have gained popularity as dietary supplements, with claims of anabolic and aphrodisiac effects, although the biologically active principles are not fully known. In an earlier chemical investigation, two new alkamides and a novel fatty acid, as well as the N-hydr...
متن کاملPeruvian Maca: Two Scientific Names Lepidium Meyenii Walpers and Lepidium Peruvianum Chacon – Are They Phytochemically-Synonymous?
Using Liquid Chromatography-Mass Spectrometry (LCMS), profiles of the two isotypes labelled under the same common name Maca deposited in the Medicinal Plant Herbarium, in Australia and Poland, but identified under two different scientific names Lepidium meyenii Walpers (L. meyenii) and Lepidium peruvianum Chacon (L. peruvianum) are presented. The two isotypes correspond to two holotypes of Peru...

متن کاملThe Methyltetrahydro-β-Carbolines in Maca (Lepidium meyenii)
Maca, a plant native to the Peruvian highlands, contains (1R,3S)-1-methyl-1,2,3,4-tetrahydro-beta-carboline-3-carboxylic acid (MTCA). The family of the tetrahydro-beta-carbolines has been associated with both biologically helpful and harmful compounds. We present evidence that MTCA is a natural constituent of Maca, and on consumption no toxicity is found. This suggests that, when consumed as mu...
