Hydantoin and thioamide analogues from Lepidium meyenii

Publication date: June 2018 Source:Phytochemistry Letters, Volume 25 Author(s): XiaoXue Tian, XingRong Peng, MuYuan Yu, YanJie Huang, Xia Wang, Lin Zhou, Minghua Qiu 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 comparing their specific rotation with data reported in literature. All of the isolates were obtained from plants for the first time. Graphical abstract
