Establishment of quality evaluation methods for pieces and standard decoction of honey-fried Descurainiae Semen / 中国中药杂志

To establish a content determination method for quality control of the pieces and standard decoction of honey-fried Descurainiae Semen. Standard decoction of honey-fried Descurainiae Semen was prepared with standardized process, and high performance liquid chromatography coupled with diode-array detector(HPLC-DAD) was used to detect its characteristic fingerprint and determine the content of quercetin-3-O-β-D-glucose-7-O-β-D-gentiobioside. In addition, the transfer rate, dry extract rate and pH value were calculated. The results showed that the established method had a high accuracy. The content of quercetin-3-O-β-D-glucose-7-O-β-D-gentiobioside in 13 batches of standard decoction was 0.03-0.12 mg·mL~(-1); the transfer rate was 13.4%-23.1%; the rate of extracts was 1.9%-5.5%, and the pH was between 5.4-5.9. The similarity coefficients were all greater than 0.85, indicating good homogeneity for the different batches of decoction. There were 7 common peaks in the characteristic chromatogram, one of which was quercetin-3-O-β-D-glucose-7-O-β-D-gentiobioside. In this paper, the established content determination and quality evaluation method for Descurainiae Semen pieces and decoction was simple, rapid and reproducible, providing reference for the quality control of honey-fried Descurainiae Semen pieces, standard decoction and its preparations.

Research Progress on Pharmacodynamic Material Basis and Quality Control of Danggui Buxue Tang / 中国实验方剂学杂志

Danggui Buxue Tang(DBT) is a famous classical formula of traditional Chinese medicine(TCM) for invigorating Qi and activating blood circulation.It is composed of Angelicae Sinensis Radix and Astragali Radix.It has the effect of enriching blood,invigorating Qi and regulating immunity,and has a high application value in clinical treatment.Because of its definite curative effect and simple compatibility,it has become a hot spot in the research field of TCM.This paper summarized and analyzed the research status of DBT from the pharmacological action,pharmacodynamic material basis,pharmacokinetics,quality control,compatibility and decoction process,so as to provide reference for the development of DBT and formulating its quality standard.
