Effects of primary processing methods on the quality of cimicifugae rhizoma
The influence of different initial processing methods on the quality of Cimicifugae Rhizoma was studied.The content of water,ash and extract in samples of Cimicifugae Rhizoma treated by different primary processing methods were determined by the method in Chinese Pharmacopoeia(2020 Edition),the determination methods of Isoferulic acid,Caffeic acid,Cimifugin and Prim-O-glucosylcimifugin were established by HPLC and the contents of each indicator components were determined.The results showed that the freeze-drying method had the lowest moisture content,the lowest ash content,the highest content of each index component,and the vacuum drying method had the highest content of extract.The established analytical method had good linear relationship,high precision,good stability and reproducibility in a certain range of quality.The quality of the air proof is better in the preliminary processing of freeze-drying.
