Xanthoxylum nitidum Roxb

Terihanine (8) was originally isolated as its 6-oxoderivative named oxyterihanine from Zcmthoxylum nitidum DC. (synonym Xanthoxylum nitidum (Roxb.) DC. Japanese name, teriha-zan o) [53], Later Ih-Sheng Chen isolated terihanine from Taiwan Z nitidum as a new quaternary alkaloid (private communication from Professor Hisashi Ishii, Chiba University, Japan). The structures of terihanine and oxyterihanine have been established by syntheris [54,55].
