Characteristic chromatogram of platelet increasing capsule as well as construction method and application thereof
The invention discloses a platelet increasing capsule characteristic chromatogram and a construction method and application thereof, and belongs to the technical field of quality control of traditional Chinese medicine compound preparations. According to the method, 13 control components including gallic acid, catechin, paeoniflorin, forsythiaside B, benzoic acid, astragalus smicus glycoside, forsythin, arctiin, liquiritigenin, benzoyl paeoniflorin, paeonol, arctigenin and indirubin are selected, a high performance liquid chromatography-mass spectrometry technology is applied, multiple batches of preparation samples are analyzed, and the content of the components in the preparation samples is determined. And establishing a characteristic spectrum of the chemical components. Compared with a traditional method, the technology has good precision and reproducibility, the data result is accurate and reliable, meanwhile, the technology can identify the 13 components at the same time under the same chromatographic condition, the analysis efficiency is remarkably improved, synchronous monitoring of multiple effective components is achieved, and the consistency and stability of the preparation quality can be guaranteed.
