Abstract:
OBJECTIVETo isolate and elucidate the constituents from stem of Chirita longgangensis var. hongyao.
METHODThe constituents were extracted with methanol and isolated by chromatography on silica gel, Sephadex LH-20 and ODS. The structures were determined by NMR and MS spectral analysis.
RESULTSeven compounds were identified as 2-hydroxy-7-methyl-9, 10-anthraquinone (1), 2-methyl-9, 10-anthraquinone (tectoquinone) (2), ursolic acid (3), vanillic acid (4), beta-sitosteryl-D-glucoside-6'-palmitate (5), beta-sitosterol (6), daucosterol (7), respectively.
CONCLUSIONCompounds 1, 2, 3 and 5 were isolated for the first time from the family Gesneriaceae, compounds 4 and 6 were isolated for the first time from the genus Chirita, and compound 7 was isolated for the frist time from Chirita longgangensis var.
