Glucosinolates from Maca (Lepidium meyenii)

Biochemical Systematics and Ecology, 2002
Maca (Lepidium meyenii Walp) is a food plant belonging to the Cruciferae family. It is very interesting because it has one of the highest frost tolerances of any cultivated plant and can be grown at high altitudes (3800–4800 m) (Bonnier, 1986). Maca dry tubers were bought from INIA (Instituto National de Investigation Agroindustrial de Huancayo, Peru);

Lignans from Lepidium meyenii and Their Anti‐Inflammatory Activities

Chemistry & Biodiversity, 2021
AbstractMeyeniines A–C (1–3), three new lignans, two known neolignans (4–5), and three known lignans (6–8) were isolated from the rhizomes of Lepidium meyenii. Their structures were identified by comprehensive spectroscopic analyses and computational methods. Compound 1 represents a unique lignan featuring an aromatic ring migration.

[Chemical constituents of Lepidium meyenii].

Zhongguo Zhong yao za zhi = Zhongguo zhongyao zazhi = China journal of Chinese materia medica, 2016
To study the chemical constituents of Lepidium meyenii, the air-dried rhizome of L. meyenii was extracted with 70% EtOH. The extract was condensed to a small amount of volume and extracted with petroleum ether, EtOAc and n-BuOH, successively. The compounds were isolated and purified by column chromatography, and identified based on spectral analyses ...

Hydantoin and thioamide analogues from Lepidium meyenii

Phytochemistry Letters, 2018
Abstract 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 ...
