从中草药勒党根茎中分离出二个化合物, 其一为已知的萜类生物碱culamtraramine, 其二为它的差向立体异构体, 为新化合物, 定名为isoculantraramine。用选择性远程核磁共振技术测定了它们的结构。

Two compounds have been isolated from the root of Zhanthoxylum avicennae(Lam). DC. The selective long-range DEPT NMR new technique has been used to connect spin systems separated by quanternary carbons and heteroatoms and total assigment of proton and 13^C NMR spectra were achieved. Compound (2) was shown to be a new terpene alkaloid which is a stereisomer of the known compound culamtraramine (1) found from this plant for the time.

Key words: TERPENE, ALKALOID, C13 NMR SPECTROMETRY, 2D NMR SPECTROMETRY
