摘 要:采用直喷离子化质谱法,通过对粉防己中的粉防己碱和防己诺林碱、广防己中的马兜铃酸A和木兰花碱的敞开式质谱行为进行研究,获得了粉防己(Stephania tetrandra)及其有毒伪品广防己(Aristolochia fangchi)的敞开式质谱轮廓,建立了直喷离子化质谱法简单快速鉴别粉防己和广防己的方法。结果表明,在正离子模式下,从敞开式质谱轮廓上,可以利用粉防己的标志性成分粉防己碱和防己诺林碱对粉防已和广防己进行快速鉴别。此方法具有简单、快速、无需样品前处理等优点,对防己药材的质量控制具有重要参考价值。研究了马兜铃酸A在敞开式质谱条件下的电喷雾电离行为,对敞开式质谱检测技术分析马兜铃酸A有借鉴意义。The ambient mass spectrometry(MS)profiles of Stephania tetrandra and its toxic adulteration,Aristolochia fangchi,were obtained by using direct spray mass spectrometry.The MS behaviors of tetrandrine and fangchinoline in Stephania tetrandra,aristolochic acid A and magnoflorine in Aristolochia fangchi were studied.A simple and rapid method for distinguishing Stephania tetrandra from Aristolochia fangchi was established by analyzing their ambient MS profiles.The results showed that under the positive ion mode,Stephania tetrandra and Aristolochia fangchi could be identified easily and effectively according to their symbolic components,fangchinoline and tetrandrine in Stephania tetrandra.The method was simple,fast,effective,with no need of sample pretreatment,which was helpful for the quality control of fangchi herbal medicine.At the same time,the study on the electrospray behavior of aristolochic acid A has certain reference significance for the ambient MS analysis of aristolochic acid A.
