Abstract:
OBJECTIVETo study the chemical constituents of Sorbus tianschanica.
METHODThe compounds were isolated and purified by recrystallization and chromatography with silica gel and resin. Their structures were identified by physicochemical properties and spectral analysis.
RESULTSeven compounds were isolated from the EtOH extraction and six structures were identified as benzoic acid (1), benzyl-O-beta-D-glucopyranoside (2), ursolic acid (3), 2alpha-hydroxyursolic acid (4), hyperoside (5), quercetin-3-O-glucoside (6).
CONCLUSIONCompounds 1-5 were isolated from S. tianschanica for the first time.
