巴山花椒根的化学成分研究

STUDIES ON CHEMICAL CONSTITUENTS OF ZANTHOXYLUM PASHANENSE N.CHAO

首次报道从芸香科花椒属植物巴山花椒（ＺａｎｔｈｏｘｙｌｕｍｐａｓｈａｎｅｎｓｅＮ．Ｃｈａｏ）根中分到９种结晶性化合物，经物理常数测定、光谱分析及化学方法，分别鉴定了两面针碱（Ⅰ）、β－谷甾醇（Ⅱ）、氧化两面针碱（Ⅲ）、胡萝卜甙（Ⅳ）、１－芝麻素（Ⅴ）、去甲白屈菜红碱（Ⅵ）、异地卡灵（Ⅶ）及另一化合物Ｙａｎｇａｍｂｉｎ（Ⅸ）。晶Ⅷ的结构尚待证实。

Nine compounds were isolated from the root of Zanthoxylum pashanense N.Chao.Of them,eight were identified as nitidine,oxynitidine,isodecarine,des-Nmethylchelerythrine,1-sesamin,yangambin,daucosterol and β-sitosterol by uv,ir,ms,nmr,element-analysis and chemical methods.While the other one,which is an alkaloid with the molecular weight 351,remains to be determined.
