[Chemical constituents of ethyl acetate fraction from Hypericum hengshanense].
OBJECTIVE
To study the constituents of ethyl acetate fraction form Hypericum hengshanense.


METHODS
The constituents were isolated and purified by chromatography on silica gel and their structures were elucidated by MS and NMR spectral analysis.


RESULTS
Ten compounds were isolated and identified as: hyperoside (1), hypericin (2), quercetin (3), quercitrin (4), sesamin (5), betulonic acid (6), rutin (7), kaempferol (8), beta-daucosterol (9), beta-sitosterol (10).


CONCLUSIONS
All compounds are obtained from this plant for the first time.
