中文摘要：

目的：研究青蒿酸对转基因西洋参（Panaxquinquefolium）冠瘿组织次生代谢物生产的影响。方法：青蒿酸西洋参冠瘿组织培养体系中，共培养2d，终止反应。产物用色谱法进行分离，根据其理化性质及波谱数据对分离所得的化合物进行结构鉴定。结果：分离并鉴定三个羟基十八碳烯酸类化合物，分别为：9，12，13-三羟基-10-十八碳烯酸（1）、11，12，13-三羟基-9-十八碳烯酸（2）和11-羟基-12，13-环氧-9-八碳烯酸（3）。结论：青蒿酸作为一种植物激素可诱导西洋参冠瘿组织培养体系中13-脂氧合酶的表达。

英文摘要：

Objective： To investigate the effect of artermisinic acid on the secondary metabolites production of Panax quinquefolium crown galls. Methods： Artemisinic acid was added into the suspended cells of Panax quinquefolium crown galls and co-culture for two days. Products were isolated with chromatographic method. Results ： Three hydroxyl octadecenoic acids [ 9,12,13-trihydroxy-10- octadecenoic acid （ 1 ）, 11,12,13-trihydroxy-9-oetadeeenoie acid （2） and 11-hydroxy-12,13-epoxy-9-oetadeeenoic acid （3） ] were i- solated from crown galls of Panax quinquefolium. Conclusion ： Artermisinic acid as one of the new type of phytohormones that might in- duce the production of 13-1ipoxygenases in crown galls of Panax quinquefolium.
