METHODS: Compounds were isolated with stratography and solvent,and their structures were identified by spectroscopy. RESULTS: Five compounds were identified as β-sitoseterol, betulin,3β-hydroxy olean-18(19)-en-28-oic acid, 2α,3β-dihydroxy-lup-20(29)-en-28-oic acid and daucosterol. CONCLUSION: The five compounds were obtained from Hovenia Thunb. for the frist time.展开更多
