摘　　要：茉莉酸是植物体内重要的伤反应特异激素,含量极低,但作用较大。当植物受到机械伤害时,茉莉酸调控一系列应激反应。12-氧-植物二烯酸(OPDA)是茉莉酸合成途径中的重要前体,与茉莉酸有密切的关系。该研究建立了一种HPLC-MS/MS分析检测方法,可同时检测植物材料中茉莉酸及其前体OPDA含量。利用该方法建立的标准曲线具有良好的线性相关性,相关系数达0.991 9–0.999 5,回收率范围为91.91%–101.56%。该方法同时具有较好的检测灵敏度,2种化合物的最低检测限为3.218和34.129 pmol。研究结果说明该方法切实可靠且具有较好的适用性。利用该方法检测了4种不同植物样品中目标化合物的含量,结果表明该方法能够用于不同植物材料中这2种活性化合物含量的检测分析。Jasmonic acid is one of the important phytohormones responding to abiotic and biotic injury. Detecting the acid is difficult because of the low content in plant material. 12-oxo-phytodienoic acid is an important precursor in the biosynthesis of jasmonic acid. In this research, we established an HPLC-MS/MS method to determine the content of these two target chemicals simultaneously in 4 types of plant materials. An external standard curve was used to calculate the content in plant material. The regression coefficiency factor of the standard curve reached 0.991 9 to 0.999 5. Spiked recovery was from 91.91% to 101.56%. The method is sensitive and available; The limits of detection of two target chemicals were 3.218 and 34.129 pmol. This method was used to determinate the contents of these two target chemicals in 4 types of plant materials.
