Sterols from stems of Momordica cochinchinesis (Lour.) Spreng.

Nguyen Thi Mai, Phan Van Kiem, Vu Kim Thu


Three known sterols, polypodine B (1), (22E,24R)-24-methylcholesta-2,22-diene-3β,5α,6β-triol (2) and chondrillasterol (3) were isolated from the stems of Momordica cochinchinesis (Lour.) Spreng. Their chemical structures were successfully determined using NMR and ESI-MS analysis as well as in comparison with the reported data. All compounds were reported from Momordica genus for the first time.

Keywords. Momordica cochinchinesis, Cucurbitaceae, steroid.
