New apotirucallane-type triterpenoids from Chisocheton paniculatus

摘要

Two new apotirucallane triterpenoids,namely chisiamols G(1)and H(2),featuring a 21,23-lactone,together with five known triterpenoids,were isolated from the twigs of Chisocheton paniculatus.The structures of the new compounds were elucidated on the basis of spectroscopic and chemical methods.
