Water-soluble chemical constituents from fruits of Phellodendron chinense var. glabriusculum

OBJECTIVE To study the water-soluble chemical constituents from the fruits of Phellodendron chinense var. glabriusculum. METHOD Chemical constituents were purified by chromatographic methods and identified by spectroscopic analysis. RESULT Eight known compounds were obtained, whose structures were elucidated as sinapyl 9-O-beta-D-glucopyranoside (1), betulalbuside A (2), arbutin (3), adenosine (4), 3,5-dihydroxyphenethyl alcohol 3-O-beta-D-glucopyranoside (5), orcinol-3-O-beta-D-glucopyranoside (6), N-trans-p-coumaroyloctopamine (7), berberine (8) respectively. CONCLUSION Compounds 1-7 were obtained from Phellodendron chinense var. glabriusculum for the first time.
