Abstract
|
|
|
|
A phytochemical investigation of Allium macrostemon Bunge (Liliaceae) afforded the new pregnane steroidal glycoside, named allimacroside F (1), along with three known glycosides, benzyl-O-α-L-rhamnopyranosyl-(1→6)-β-D-glucopyranoside (2), phenylethyl-O-α-L-rhamnopyranosyl-(1 →6)-β-D-glucopyranoside (3), (Z)-3-hexenyl-O-α-L-rhamnopyranosyl-(1→6)-β-D-glucopyranoside (4). The identification and structural elucidation of a new compound (1) was carried out based on spectral data analyses (1H-NMR, 13C-NMR, 1H-1H COSY, HSQC, HMBC, and NOESY) and HR-FAB-MS.
