ABSTRACT
Objective:
To establish the UPLC specific chromatogram and HPLC content determination methods of multi-index components about the material reference of classical Huaganjian and build its quality control system.Methods:
According to the ancient books and combining with the previously inspected process, 18 batches of Huaganjian material reference from different origins were prepared. The specific chromatogram was established by using UPLC. Similarity was calculated by using TCM Chromatographic Fingerprint Similarity Evaluation Software (2012). Combining with orthogonal partial least squares discriminant analysis, we excavated the main components that affected the quality of Huaganjian material reference from different batches and origins. Three of these index components (paeoniflorin, hesperidin, paeonol) from prescription sovereign drug, minister drug, and assistant drug were selected and used as indicators for content determination of Huaganjian material reference. HPLC content determination methods were established and the content of 18 batches of samples was determined respectively.Results:
The similarity of the specific chromatogram was ≥ 0.989. Thirty-three common peaks were calibrated, and eight common peaks were identified by chemical composition (gallic acid, geniposide, paeoniflorin, hesperidin, didymin, paeonol, sinensetin, and 3,5,6,7,8,3',4'- heptamethoxyflavone). Nine index components that affected the stability between batches were found out (Peak 31, 20, 11, 13, 22, 33, 21, 29, 1). Paeoniflorin, hesperidin, and paeonol were selected as content determination indicators. The content range of these components in material reference was 1.28%-1.95% paeoniflorin, 0.91%-1.02% hesperidin, 0.48%-0.57% paeonol.Conclusion:
The quality control method of the material reference of classic prescription Huaganjian was established preliminarily through the UPLC specific chromatogram and HPLC content determination of index components. This method was rapid, simple, feasible, reproducible, stable and could provide a theoretical basis for the subsequent development and quality control of Huaganjian preparations.
