[Research on petroleum ether extract of rhizoma Drynariae].
OBJECTIVE
To study the petroleum ether extract of Rhizoma Drynariae.


METHODS
Solvent extraction silica gel column isolation, and structure elucidation by physico-chemical evidence and spectral analysis.


RESULTS
Three compounds were isolated and elucidated as fern-9(11)-ene, hop-22(29)-ene and cyclolaudenol.
