STUDIES ON SESQUITERPENE LACTONES FROM ILLICIUM MINWANENSE B.N. CHANG ET S.D ZHANG

A new sesquiterpene lactone was isolated along with the known anisatin(I),pseudoanisatin(II),6-deoxypseudoanisatin(III)and shikimic acid(IV)from pericarps of the fruit of IUicium minwanense B. N. Chang et S.D. Zhang,family Magnoliaceae,collected in Anhui provence.This new sesquiterpene lactone exhibited no toxicity in mice. Its structure was elucidated as V andnamed as minwanensin.
