Abstract:
OBJECTIVETo study the constituents of Hypericum attenatum.
METHODThe compounds were isolated by chromatography on silica gel, the structures were identified by their physical, chemical properties and IR, NMR and MS spectral data respectively.
RESULTNine compounds were isolated and identified as p-hydroxybenzoic acid (1), 6, 9-dihydroxy-4, 7-megastigmadien-3-one (2), butyl alcohol-O-alpha-D-fructoside (3), 24-ethyl-cholest-7-ene-3 beta, 5 alpha, 6 beta-thtroil (4), hexanol (5), 1 beta, 6 alpha-dihydroxyeudesmane-4(14)-ene (6), beta-sitosterol (7), 5, 5-dimethyl-4-hydroxy-tetrahydrofuran-2-one (8), beta-daucosterol (9).
CONCLUSIONAll of the compounds were isolated from H. attenuatum for the first time.
