Abstract: From the bark of Zanihoxyllum myriac ant hum Wall. ex Hook. f. ten compounds were isolated, which were identified as 1-asarinin (1), fargesin ( 2 ), 1 -syringaresinol ( 3 ), γ -sanshool ( 4 ), hydroxyl γ -sanshool ( 5 ), alatamide (6), dihydroalatamide (7), tembamide (8), nitidine ( 9 )and isoarnot-tianamide (10) by means of spectroscopic and chemical methods. On the other hand, the chemotaxonomy of Zanthoxyllum with its related taxa also were discussed. Zanthoxyllum (includes subgen. Zanthoxyllum and subgen. Fagara) as a primi-tive genus of Rutaceae and which to be related with some primitive Angiosperms in phylogenetic history have got the supports from the chemical evidence.

Key words: Zanthoxyllum myriacanthum
