[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.
