Abstract:
Testing and analysis of chemical markers is currently the prevailing approach for quality assessment of traditional Chinese medicines. However,several important issues remain to be addressed,including the trade-off between accuracy and coverage. In this study,in order to give full play to the advantages of their respective methods and provide technical support for more comprehensively and rapidly evaluate the quality of Danshen Injection products,a fingerprint method was coupled with quantitative analysis of multicomponents by single marker( QAMS),with Danshen Injection as the carrier. Ultra performance liquid chromatography( UPLC) was used to establish the quantitative fingerprint. The UPLC fingerprints contained 13 common peaks,11 of which were identified by using ultra performance liquid chromatography-quadrupole time-of-flight mass spectrometry( UPLC-QTOF-MS). Furthermore,with sodium danshensu as the internal reference substance,relative correction factors( RCFs) of protocatechuic aldehyde,caffeic acid,rosmarinic acid,lithospermic acid,and salvianolic acid B were calculated through slope analysis method,and the QAMS method was adopted to determine the contents of these 6 components. The UPLC fingerprint was employed to assess the consistency of 12 batches of Danshen Injection,which showed good batch-to-batch consistency with similarity higher than 0. 99. In the comparison of contents of the six constituents obtained by QAMS and external standard method( ESM),RSD was all less than 4. 3%,indicating the good accuracy of the QAMS method. The QAMS method developed in this study combined with UPLC fingerprint can comprehensively reflect the internal quality of Danshen Injection when only the reference substance sodium danshensu is consumed,with greatly reduced detection cost and time. It provides a technical basis for further improving the quality standard of Danshen Injection.
