Abstract:
OBJECTIVETo study the chemical constituents of Davidia involucrata var. vilmoriniana.
METHODThe chemical constituents were isolated by column chromatography on silical gel and sephadex LH -20. Their structures were elucidated on the basis of spectral analysis and physical constants.
RESULTSeven compounds were isolated from this plant and the structures of them were identified as 3, 4, 5-trihydroxybenzoic acid (1), ellagic acid (2), maleic acid (3), quercetin (4), quercetin-3-O-beta-D-galactoside (5), 2alpha, 3alpha, 19alpha, 23-tetrahydroxyurs-12-en-28-oic-acid-28-O-beta-D-glucopyranosyl ester (6), ethyl brevifolin carbosylate (7), respectively.
CONCLUSIONCompounds 1-7 were isolated from this plant for the first time.
