Two New Spirostanol Glycosides from the Aerial Part of Cordyline fruticosa
摘要
Two new spirostanol glycosides, (25S)-5α-spirosta-1β,3β-diol 1-O-α-L-rhamnopyranosyl-(1→2)-β-Dfucopyranoside (1) and 5α-spirost-(25)27-ene-1β,3β-diol 1-O-α-L-rhamnopyranosyl-(1→2)-(4-Osulfo)-β-D-fucopyranosyl 3-O-α-L-rhamnopyranoside (2), were isolated from the aerial part of Cordyline fruticosa (L.) A. Chev. Their structures were determined by spectroscopic analysis 1D and 2D NMR, and mass spectrometry (HR-ESI-MS in positive mode).
