摘 要:摘 要:以茉莉酸(jasmonic acid, JA)和茉莉酸甲酯(methyl jasmonate, MeJA)为代表的茉莉酸类物质(jasmonates, JAs)是一种新型天然植物生长调节剂,具有广谱的生理效应,存在于多种高等植物体内。内源茉莉酸类激素通常以多种手性异构体存在,且含量超微(约为ng/g鲜重),因此,对内源性茉莉酸类激素进行准确的定性、定量分析具有很大的难度,研究高效分离富集、高灵敏度检测以及分离与检测联用等分析方法,对加速植物激素分子作用机理研究具有重大意义。该文就JAs(含其衍生物及手性异构体)的分离与检测技术进行了综述,包括各种色谱、色谱与质谱联用技术、毛细管电泳技术、免疫分析等各种方法,并展望了JAs分析方法未来的发展趋势。

Abstract: Abstract: Jasmonic acid (JA) and methy jasmonate (MeJA) have been recognized as a new type of natural plant growth regulator and exist in the plant kingdom at very low concentration. JAs have a very wide range of physiological activities. As endogenous jasmonates exist in enantiomers in nature and at level of nanogram/per gram fresh weight, it is very challenging work to develop rapid and accurate method for qualitative and quantitative analyses of JAs. This review paper summarizes the recent advances in the analysis of jasmonates including chromatography, capillary electrophoresis, chromatography-mass spectrometry and immunoassay.
