Three new cucurbitane triterpenoids 1-3 and one new steroidal glycoside 4, were isolated together with ten known compounds from Momordica charantia. The structures of new compounds were determined to be 19(R)-n-butanoxy-5 beta,19-epoxycucurbita-6,23-diene-3beta,25-diol 3-O-beta-glucopyranoside (1), 23-O-beta-allopyranosylecucurbita-5,24-dien-7(More)
Four new alkaloids, sinensines B–E (1–4), together with one known alkaloid, sinensine (5), were isolated from the fruit-ing bodies of Ganoderma sinense. Their structures were elucidated on the basis of 1D and 2D NMR spectra analysis. The structure of sinensine E was confirmed by X-ray crystallographic analysis of its acetyl product (4a).
