Shuxuening injection (SXNI) is the pharmaceutical preparations of Ginkgo biloba for treating coronary heart disease, stenocardia and ischemic cerebrovascular disease. In order to guarantee the clinical efficacy and drug safety, the chemical and biological variation of SXNIs from different manufacturers should be monitored and controlled. In this study, a strategy for the quality control of SXNIs was established. A widely targeted metabolomics method based on scheduled MRM (sMRM) was developed and 86 compounds with good linearity, sensitivity, and repeatability was selected for relative quantitation to reveal the chemical variation among 7 SXNI manufactures. 10 compounds with big content variation among differen...
