ABSTRACT
<p><b>OBJECTIVE</b>To study the chemical constituents from the roots of Craibiodendron henryi.</p><p><b>METHOD</b>Various chromatographic techniques were used to isolate and purify the constituents. The structures were elucidated by chemical evidence and spectral methods.</p><p><b>RESULT</b>Twelve 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).</p><p><b>CONCLUSION</b>Compounds 1-12 were isolated from this plant for the first time.</p>
