摘要
An approach for the identification of multiple components in traditional Chinese medicine injections (TCMIs) using a combination of hydrophilic interaction chromatography (HILIC) and reversed‐phase liquid chromatography (RPLC) coupled with time‐of‐flight mass spectrometry (TOFMS) was developed for the quality control of Guanxinning injection (GXNI), a widely used TCMI, composed of Salvia miltiorrhiza and Ligusticum Chuanxiong . A total of 50 compounds from five compound classes, including saccharides, amino acids, organic acids, phenolic acids and phthalides, were identified or tentatively characterized on the basis of accurate mass measurements and subsequent TOFMS product ions. Six groups of isomers of phenolic acids and saccharides were tentatively distinguished. It was observed that the ESI‐TOFMS fragmentation behavior of phthalides was different in negative and positive ion mode, and the fragmentation pathways were tentatively elucidated using structurally‐relevant product ions. Several highly polar constituents were characterized for the first time from GXNI by HILIC/TOFMS. In addition, all the constituents identified from GXNI were further assigned in the two individual crude drugs. The integrated strategy has provided a powerful approach for the separation and identification of the multiple components in GXNI, and it has also assisted in the establishment of methods for the comprehensive safety and quality evaluation of TCMIs.
