Chemical composition of Lepidium meyenii
Food Chemistry, 1994Abstract Lepidium meyenii Walpers, a tuber of Andine origin still cultivated in Peru for local preparation, was studied. The carbohydrate, lipid, protein, fibre and also the amino-acid, fatty acid, mineral and sterol fractions were determined. The results show that the tuber is nutritionally interesting. Alkaloid-like compounds were also found.

Does Lepidium meyenii (Maca) improve seminal quality?
Andrologia, 2020Maca (Lepidium meyenii) is a herbaceous plant grown at over 4,000 m in Peru. It has been studied worldwide for its properties on fertility. Previous studies have assessed maca effects on semen quality, but there is need of randomised, double-blind trials in order to make clinical decisions.

Neuroprotective effects of Lepidium meyenii (Maca)
Annals of the New York Academy of Sciences, 2010The neuroprotective activity of the plant Lepidium meyenii (Maca) was studied in two experimental models: in vitro and in vivo. Crayfish neurons were pretreated with vehicle or the pentane extract from Maca, subjected to H2O2, and their viability determined microscopically and chemically.

Lepidium meyenii (Maca) does not exert direct androgenic activities
Journal of Ethnopharmacology, 2006Maca is the edible root of the Peruvian plant Lepidum meyenii, traditionally employed for its purported aphrodisiac and fertility-enhancing properties. This study aimed at testing the hypothesis that Maca contains testosterone-like compounds, able to bind the human androgen receptor and promote transcription pathways regulated by steroid hormone ...

Hydantoin and thioamide analogues from Lepidium meyenii
Phytochemistry Letters, 2018Abstract Four new compounds, including two hydantoin derivatives, macahydantoins C and D (1, 2), one urea derivative, macaurea A (3) and one thioamide analogue, macathioamide A (4), were isolated from the tube of Lepidium meyenii (Maca). Their chemical structures were determined by analyzing spectroscopic data, especially 1D and 2D NMR spectra, and ...
