    Abstract:
    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). CONCLUSION: Compounds II - V are isolated from this plant for the first time.
