Abstract:
OBJECTIVETo study the chemical constituents from the roots of Craibiodendron henryi.
METHODVarious chromatographic techniques were used to isolate and purify the constituents. The structures were elucidated by chemical evidence and spectral methods.
RESULTTwelve compounds were isolated from the ethyl acetate soluble fraction of the 95% ethanolic extract and their struc- tures were elucidated as quercetin (1), quercetin-3-O-rhamnicoside (2), quercetin-3-O-arabinofuranoside (3), (-)-epicatechin (4), proanthocyanidin A-2 (5), procyanidin B-2 (6), (-)-isolariciresinol-2a-O-beta-D-xylopyranoside (7), lyoniside (8), sitoster-yl-3beta-glucoside-6'-O-palmitate (9), beta-sitosterol (10), daucosterol (11) and octacosanoic acid (12).
CONCLUSIONCompounds 1-12 were isolated from this plant for the first time.
