To study the chemical constituents of Dryopteris fragrans.
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.
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).
Compounds II - V are isolated from this plant for the first time.
