[Abstract]:With the application of "quality from Design" and other advanced drug quality control concepts in production practice, the focus of quality control of traditional Chinese medicine is also transferred from finished product inspection to raw material quality control and pharmaceutical process quality control. According to the important operation unit, using process analysis technology to establish an effective process monitoring method can significantly improve the quality control level of pharmaceutical process, and then improve the consistency of quality of traditional Chinese medicine. In this paper, the alcohol precipitation technology of Shenqi Fuzheng injection was taken as the research object, and the application of near infrared spectroscopy combined with multivariate data analysis technology was carried out, mainly including the following contents: 1: 1. An online monitoring model for primary alcohol precipitation process of Astragalus membranaceus was established. The monitoring model of primary alcohol precipitation process of Astragalus membranaceus was established by combining near infrared spectroscopy with multivariable statistical process control. By calculating the statistics of Hotelling T2 and DModX at each time point, we observed whether the process was in a controlled range and judged whether the process was running normally. The results show that the model has better monitoring ability and can identify process anomalies in time. A fast near-infrared spectrum analysis method for the supernatant of primary alcohol precipitation of Codonopsis pilosula was established. The representative sample set was obtained by experimental design and concentration-dilution method. Each modeling step was optimized one by one, and the prediction performance of the model was good, and the rapid quantification of Codonosine, total flavonoids, pigment and total solids in the supernatant of primary alcohol precipitation of Codonopsis pilosula was achieved. An on-line near-infrared spectrometric analysis of secondary alcohol precipitation of Astragalus membranaceus was established. A HPLC-UV-ELSD method was established for the determination of isoflavone glycosides in Astragalus membranaceus alcohol precipitate, Astragalus saponin 鈪,
