Abstract:
OBJECTIVETo study the chemical constitutes in Rabdosia japonica var. galaucocalyx .
METHODThe compounds were isolated by nomal phase silica gel chromatography. The structures were identified by physical and spectral data.
RESULTNine triterpenoids were isolated and identified as friedelin (I), 3beta, 28-dihydroxy-ursane (II), ursolic acid (III), 3beta-acetyloxy-ursolic acid (IV), 2alpha, 3alpha-dihydroxy-urs-12-en-28-oic acid (V), 2alpha, 3alpha, 23-trihydroxy-urs-12-en-28-oic acid (VI), oleanic acid (VII), beta-sitosterol (VIII), daucousterol (IX).
CONCLUSIONCompounds I, II, IV, V and VI were isolated from R. japonica var. galaucocalyx for the first time.
