Abstract:
OBJECTIVETo study the chemical constituents of the fruit of Rubus chingii.
METHODThe compounds were isolated and purified by recrystallization and chromatography with silica gel column and Sephadex LH-20 column. Their structures were identified by physicochemical properties and spectral analysis.
RESULTEleven compounds were isolated as oleanic acid (I), ursolic acid (II), maslinic acid (III), 2alpha-hydroxyursolic acid (IV), arjunic acid (V), hexacosyl p-coumarate (VI), tiliroside (VII), stearic acid (VIII), lacceroic acid (IX), beta-sitosterol (X), daucosterol (XI).
CONCLUSIONCompounds I, II, III, IV, V, VI, VIII, IX, XI were isolated from R. chingii for the first time.
