Investigation of the tuber constituents of maca (Lepidium meyenii Walp.).
Lepidium meyenii, known in South America as maca, has received attention worldwide as a powerful energizer that improves physical and mental conditions and increases fertility. Because of these reports, we investigated the secondary metabolites of the tuber of maca. The methanol extract of the tuber of maca contained, in addition to free sugars and amino acids, the following: uridine, malic aci...
متن کاملComparison of Mineral Element Content in a Functional Food Maca (Lepidium meyenii Walp.) from Asia and South America
Contents of eight mineral elements in maca (Lepidium meyenii Walp.) from China and Peru were determined by inductively coupled plasma optical emission spectroscopy. Cu contents in maca samples from China (2.5-31 mg kg(-1) dry weight, dw) were higher than the samples from Peru (<2.1 mg kg(-1) dw). Na in two samples from China was found to be significantly of high content (2400 and 2600 mg kg(-1)...
متن کاملNew 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 کاملIdentification and characterization of microRNAs and their targets in high-altitude stress-adaptive plant maca (Lepidium meyenii Walp)
MicroRNAs (miRNAs) are endogenous, short (~21-nucleotide), non-coding RNA molecules that play pivotal roles in plant growth, development, and stress response signaling. In this study using recently published draft genome sequence of a high-altitude plant maca (Lepidium meyenii Walp) and applying genome-wide computational-based approaches, a total of 62 potentially conserved miRNAs belonging to ...
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...
