[Studies on phloroglucinol derivatives of Dryopteris fragrans L].
OBJECTIVE
To study the phloroglucinol derivatives of Dryopteris fragrans.


METHODS
Isolation and purification were carried out on repeated silica gel, Sephadex LH-20 column chromatography and prepare HPLC. The structures of the compounds were determined by physicochemical properties and spectral analysis.


RESULTS
Four compounds were isolated and identified as aspidin PB (I), dryofragin (II), aspidinol (III), aspidin BB (IV).


CONCLUSIONS
Compounds IV is isolated from this plant for the first time.
