The triple quadrupole LC-MS system was operated under selected reaction monitoring(SRM) mode using the electrospray ionization technique in negative mode. Quantification was performed using SRM of the transitions m/z 717→519 for Sal B,197→135 for DSS,and 321→152 for the IS,respectively.
选用电喷雾电离(ESI)三重四极杆串联质谱仪,在负离子模式下以选择反应监测(SRM)方式进行检测,用于定量分析的离子反应分别为m/z 717→519(丹酚酸B)、m/z 197→135(丹参素)和m/z 321→152(氯霉素)。
