[Study on the chemical constituents in herb of Hypericum attenuatum].
OBJECTIVE
To study the constituents of Hypericum attenatum.


METHODS
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.


RESULTS
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).


CONCLUSIONS
All of the compounds were isolated from H. attenuatum for the first time.
