ABSTRACT
Objective The fingerprint of volatile components from three breeds of Radix Curcumae was compared to supply evidence for the standard of quality control of Radix Curcumae.Methods Gas chromatography was used to establish fingerprint of Radix Curcumae and GC-MS chromatography was applied to identify its characteristic peaks. The similarity of fingerprint was evaluated by computing method.Results The fingerprint had its similarity and characteristics in different breeds of Radix Curcumae. The fingerprint detection is a good method for identifying Radix Curcumae,RSD 2.53 %.Conclusion This method is simple and effective for identifying different breeds of Radix Curcumae and can be used to control the quality of medicinal material of Radix Curcumae.
ABSTRACT
Objective To improve the quality standard of Anti- virus Oral Liquid. Methods Rhizoma Anemarrhenae and Rhizoma Acori tatrinowii in Anti- virus Oral Liquid were identified by TLC. Forsythin in Fructus Forsythiae was determined by HPLC. Results Rhizoma Anemarrhenae and Rhizoma Acori tatrinowii can be identified by TCL. The linearity of forsythin in the range of 0.1～ 0.6 ? g/? L was good, r=0.9998. The average recovery is 99.87 % , RSD=1.93 % . Conclusion The methods is accurate, reliable and specific and can be used for the quality control of Anti- virus Oral Liquid.
ABSTRACT
AIM: Terminalia chebula contained hydrolysable tannins up to about 35%. It was necessary to establish a chromatographic fingerprint to meet the quality control need effectively. METHODS: HPLC method was carried out with 3 kinds of the mobile phase , namely, A∶ 0.05mol?L -1 Phosphoric acid/ 0.05mol?L -1 Potassium dihydrogen phosphorate aqueous solution, B: methanol and C: Ethyl acetate, running in gradient mode based on the previous experiment. RESULTS: A marked peaks of HPLC fingerprint of the raw material, the extracts and its final product consisted of gallic acid, terchebulin, chebulamin, chebulagic acid and chebulinic acid. CONCLUSION: The fact has depicted that chromatographic fingerprint is a powerful tool for in-process-quality supervisory control and dynamic analysis of the active constituents during manufacture procedure of immature fruit products of Terminalia chebula.
