    Abstract:
    OBJECTIVE: To study the constituents of Hypericum attenatum. METHOD: The 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. RESULT: Nine 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).
