Abstract
OBJECTIVE: To study the petroleum ether extract of Rhizoma Drynariae. METHOD: Solvent extraction silica gel column isolation, and structure elucidation by physico-chemical evidence and spectral analysis. RESULT: Three compounds were isolated and elucidated as fern-9(11)-ene, hop-22(29)-ene and cyclolaudenol. CONCLUSION: All the three compounds are triterpenoids.
