[Studies on the chemical constituents of Dryopteris fragrans].
OBJECTIVE
To study the chemical constituents of Dryopteris fragrans.


METHODS
The constituents of CHCl3-soluble portion and ethyl acetate-soluble portion from the alcohol extract were isolated and purified by means of chromatography. All the compounds were identified by their physical characteristics and spectral features.


RESULTS
Five compounds were isolated and identified as beta-sitosterol (I), rutin (II), quercetin (III), quercetin-3-O-beta-D-pyranglucoside (IV) and 5,7-dihydroxy-2-hydroxymethyl chromone (V).


CONCLUSIONS
Compounds II - V are isolated from this plant for the first time.
