Abstract:
OBJECTIVETo investigate the chemical constituents of the leaves of Aquilaria sinensis, and provide a certain of basis for the comprehensive uses of the plant of A. sinensis.
METHODThe chemical constituents were isolated by various column chromatographic method. The structures were identified by spectral analyses of NMR, MS, et al.
RESULTThirteen compounds were isolated and identified as 7-hyroxy-5, 4'-dimethoxy flovone (1), 5-hydroxy-7, 4'-dimethoxy flavone (2), luteolin-7-3',4'-trimethyl (3), isocorydine (4), 4-hydroxybenzoic acid (5), triacontenoic (6), hentriacontane (7), alpha-stigmasterol (8), epifriedelanol (9), friedelan (10), friedelin (11), genkwanin (12), 5, 4'-dihyroxy-7, 3'-dimethoxy flovone (13).
CONCLUSIONCompound 4 was obtained from this genus for the first time, compounds 1, 6-11, 13 were obtained from this species for the first time.
