Abstract:
OBJECTIVETo study the chemical constituents from n-BuOH portion of ethanolic extract from the stem of Luculia pinceana.
METHODThe column chromatographic techniques were applied to isolate constituents. A combination of IR, FAB-MS, NMR and 2D NMR spectroscopy was used to identify structures.
RESULTSeven compounds were isolated from the n-BuOH fraction and their structures were elucidated as vogeloside (1), epi-vogeloside (2), loganoside (3), loganin (4), cincholic acid 28-O-beta-D-glucopyranosyl ester (5), cincholic acid-3-O-beta-D-glucopyranoside, 28-O-beta-D-glucopyranosyl ester (6), cincholic acid-3-O-beta-D-glucopyranoside (7).
CONCLUSIONCompounds 1-7 were isolated from the genus for the first time.
