刺异叶花椒化学成分研究

STUDIES ON THE CHEMICAL CONSTITUENTS OF ZANTHOXYLUM DIMORPHOPHYLLUM HEMSL. VAR SPINIFOLIUM RHED. ET WILS

目的 研究刺异叶花椒 (ZanthoxylumdimorphophyllumHemsl.varspinifolumRhed .etWils)的化学成分。方法 采用现代色谱技术进行化学成分的分离 ,运用光谱方法确定所分离化合物的结构。结果 分离得到 5个化合物 ,分别鉴定为 6 (3′ 甲基 2′ ,3′ 丁二醇基 ) 7 乙酰氧基香豆素 (I) ,6 (3′ 甲基 2′ ,3′ 丁二醇基 ) 香豆素 7 O β D 吡喃葡糖苷 (II) ,正二十六烷酸 (III) ,葡萄内酯 (IV) ,5 ,3′ 二羟基 4 甲氧基 二氢黄酮 7 [O β D 吡喃葡萄糖 (6→ 1) α L 鼠李糖 ]苷 (V)。结论 化合物I -V均为首次从该植物中分得 。

AIM To study the chemical components from the dried roots of Zanthoxylum dimorphophyllum Hemsl. var spinifolium Rhed. et Wils. METHODS Modern chromatography was used to isolate chemical components and the compounds isolated from Zanthoxylum dimorphophyllum Hemsl. var spinifolium Rhed. et Wils were identified by various spectral methods. RESULTS Five compounds were isolated and identified as 6 (2′,3′ dihydroxy 3′ methybutyl) 7 acetoxy 2H 1 benzopyran 2 one (I), 6 (2′,3′ dihydroxy 3′ methybutyl) 7 (β D glucopyranosyloxy) 2H 1 benzopyran 2 one (II), hexacosanoci acid (III), aurepten (IV), 6 [6′ O ( deoxy α L mannopyranosyl) β D benzopyran 4 one (V). CONCLUSION All of the above compounds were isolated from the plant for the first time, among them, I is a new compound.
