[Study on terpene of Dryopteris fragrans L].

ABSTRACT

OBJECTIVE: To study the terpene 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 10-hydroxyl-15-oxo-alpha-cadinol (I), albicany acetate (II), alpha-cadinene (III), albicanol (IV). CONCLUSION: Compounds I is isolated from this plant for the first time.
