摘要: 旨在建立一种分析丹参植物体内脱落酸含量的方法,揭示AM真菌对丹参脱落酸含量的影响。本研究采用超高效液相色谱-三重四级杆质谱(UPLC-MS/MS),植物激素采用异丙醇:水:HCI(2:1:0.002)提取液提取,二氯甲烷萃取,进而应用超高效液相色谱-质谱联用,以多反应监测(MRM)进行定量分析。脱落酸在线性范围内的相关系数(r)为0.9986;检出限为0.0466 ng/mL;植物根和叶片高、中、低3个浓度加标回收率在80.48%~96.41%之间;日内和日间精密度RSD均低于10.0%;稳定性和重复性RSD均低于5.0%,接种AM真菌丹参植物根和叶片中脱落酸含量均显著低于对照组。该方法具有良好的灵敏度、精密度和回收率,适用于丹参植物内源激素脱落酸的含量检测。

Abstract: The study aims to establish a method analyzing the content of endogenous abscisic acid in salvia miltiorrhiza, and reveal the effect of arbuscular mycorrhizal (AM) on the content of abscisic acid. The abscisic acid analysis was conducted using ultra-high performance liquid chromatography-triple quadrupole mass spectrometry (UPLC-MS/MS). The phytohormone was extracted with 2-propanol: H2O: concentrated HCl (2:1:0.002, v/v/v), extracted by dichloromethane, and determined using reverse-phase liquid chromatography-tandem mass spectrometry, and the quantitative analysis was carried out with multiple reaction monitoring. In the linear ranges, the correlation coefficient (r) of abscisic acid was 0.9986. The detection limits was 0.0466 ng/mL. The recovery rates of high, medium and low concentration were 80.48%-96.41% in root and leaf. The relative standard deviations (RSD) of inter-day precision and within-day precision were under 10.0%. And RSD values of stability and reproducibility were lower than 5.0%. After inoculated with AM fungi, the content of abscisic acid in root and leaf were significantly lower than the control group. This method had good sensitivity, precision, recovery, and could be used to determine the content of abscisic acid in salvia miltiorrhiza.
