崖椒茎的化学成分

The chemical constituents of Zanlhoxylum schinifolium Sieb. et Zucc

从崖椒（Zanthoxglum schinifolutm Sieb.et Zucc.)茎的石油醚、二氯甲烷提取物中分离得到8个化合物。经物理常数测定及光谱（UV,IR,MS,NMR)分析鉴定其为（1）白鲜碱（dictamning),（2）茵芋碱（skimmianine),(3)滨蒿内酯（scoparone),(4)崖椒内酯（schinifolin),(5)莨菪亭（scopoletin),（6）7-羟基-8-甲氧基香豆素（7-hydroxy-8-methoxycoumarin),（7）N-甲基弗林辛（N-methylflindersine),（8）β-谷甾醇（β-sitosterol),其中化合物（5）、（6）和（7）为首次从该植物中分离。

Eight compounds-(1) dictamnine, (2) skimmianine, (3) scoparone, (4) schinifolin, (5) scopoletin , (6) 7-hydroxy-8-methoxycoumarin, (7) N- methylflindersin , (8) β-sitosterol were isolated from the stems of Zanthoxylnm schinifolium Sieb. et Zucc. collected in Yixing County, Jiangsu Province. The structure determination was based upon spectroscopic analysis (UV, IR, MS, NMR). Compounds (5) , (6) and (7) were first isolated from this species.
