中文摘要	建立了 SPE-HPLC-MS/MS同时测定新鲜马尾松松针中水杨酸和茉莉酸2种内源植物激素的方法。新鲜马尾松松针样品经液氮磨碎后,用甲醇/水/甲酸(80:19:1,V/V/V)溶液涡旋提取,经混合型阳离子交换小柱(Oasis MCX)净化,采用Symmetry C_(18)(3.9 mm * 150 mm, 5 mum)色谱柱分离,以水(含0.1%甲酸(V/V)和10 mmol/L甲酸铵)和甲醇为流动相,梯度洗脱,采用电喷雾电离,负离子扫描多反应监测模式(MRM)进行检测,2种植物激素均采用相应的同位素内标进行定量。结果表明,水杨酸和茉莉酸2种目标化合物的方法检出限分别为1.5 mug/kg和1.0 mug/kg,线性范围为2 ~100 mug/L(r>0.995),添加回收率为78.5% ~96.2%,RSD为5.7% ~11%。方法实现了同时测定新鲜马尾松松针中水杨酸和茉莉酸,可推广应用于其它植物组织中水杨酸和茉莉酸含量的分析。
英文摘要	This paper describes a method to detect and quantitate the endogenous plant hormones salicylic acid and jasmonic acid by means of solid phase extraction and high performance liquid chromatography-tandem mass spectrometry in fresh leaves of pinus massoninan. Deuterium-labeled [~2H_5] ( ) -jasmonic acid and [~2H_4] -salicylic acid were used as internal standards. Fresh leaves of Pinus massoninan ( 1 g) were cryogenically grinded by liquid nitrogen, extracted with methanol/water/ formic acid (80:19:1), and then purified on an Oasis MCX SPE cartridge. The separation was performed on a Symmetry C_(18) column by using methanol and water ( containing 0.1% formic acid and 10 mmol/L ammonium formate) as mobile phases with gradient elution. The analytes were detected by tandem mass spectrometry in multiple reaction monitoring (MRM) mode. The electrospray ionization (ESI) source was used for the quantitative analysis in negative mode. The results showed that the limits of detection ( LODs) for salicylic acid and jasmonic acid were 1.5 mug/kg and 1.0 mug/kg. The calibration curves of the two analytes were linear in the range of 2 ~ 100 mug/L with the correlation coefficients higher than 0.995. The respective mean recoveries were found to be in the range of 78.5% ~96.2%,and the RSDs were 5.7% ~11%. It was applicable to the analysis of salicylic acid and jasmonic acid in other plant issues. This method is simple, fast, sensitive and accurate.
