Studies on Quality Standard of Zhixueling Capsule

Abstract:

Objective:a method for the quality control of Zhixueling capsule was modified and improved.Method:Radix sanguisorbae,Heaba taraxaci were identified by TLC.A method of thin layer densitometry to determine astragalin-A,the main effective component from Radix astragali in the capsule,was developed.Result:The studies on the quality control showed that the characteristics for identification by TLC were distinct.The quantification method had the linear range of 0.6～3.6μg.The average recovery was 102.68% and its RSD was 3.2%.Conclusion:The quality standard of the capsule was modified and improved.The methods for identification and quantification were simple,reproducible and realizable.
