摘要: 目的:建立液质联用法分析滇紫草中印美定、石松胺、蓝蓟定及其氮氧化物的含量。方法:采用沃特世HSS T3(长度100 mm、直径2.1 mm,粒径1.8 μm)为色谱柱,以各含0.05%甲酸的乙腈水系统为流动相,梯度洗脱,流速为0.3 mL·min-1;进样量为1 μL;电喷雾离子源,正离子多反应监测模式测定。结果:滇紫草中4种成分分别在0.972~97.2 ng·mL-1、0.988~98.8 ng·mL-1、1.024~102.4 ng·mL-1、0.996~99.6 ng·mL-1范围内线性关系良好(r>0.999 0),回收率分别为93.5%、89.2%、88.1%和85.4%,RSD分别为3.5%、4.2%、3.2%和4.3%。结论:该方法专属性强,准确性好,可用于滇紫草中吡咯里西啶生物碱类成分的检测。

Abstract: Objective: To establish a UPLC-MS/MS method for the analysis of intermedine, lycopsamine, echimidine and echimidine N-oxide in Onosmae Radicis Suber. Methods: Four analytes were separatied by a HSS T3 column(length 100 mm, diameter 2.1 mm, particle size 1.8 μm) with a mobile phase of acetonitrile-water(containing 0.05% formic acid, respectively) by gradient elution with the flow rate of 0.3 mL·min-1.The injection volume is 1 μL. The MS system was operated by using electrospray ionization in the positive ion mode, and the scan mode was in multiple reactions monitoring mode. Results: The above-mentioned four components showed good linear relationships within the ranges of 0.972-97.2 ng·mL-1, 0.988-98.8 ng·mL-1, 1.024-102.4 ng·mL-1, and 0.996-99.6 ng·mL-1(r>0.999 0). The average recoveries were 93.5%, 89.2%, 88.1%, and 85.4% with RSD of 3.5%, 4.2%, 3.2%, and 4.3%, respectively. Conclusion: This method has strong specificity and good accuracy, and can be used for the detection of pyrrolizidine alkaloids in Onosmae Radicis Suber.
