Abstract

OBJECTIVE: To establish the quality standard for Qiqilian capsule. METHODS: TLC was used to identify Astragali Radix and Panax notoginseng. A HPLC-ELSD was used to measure the content of astragaloside Ⅳ in Qiqilian capsule. RESULTS: The qualitative identifications with TLC were specific without interference from negative control. The liner range of astragaloside Ⅳ were 0.529 5-4.236 0 μg(r=0.999 7) with average recovery of 99.34%(RSD=1.10%,n=6). RSDs of precision, stability and reproducibility tests were all lower than 2%. CONCLUSIONS: Established standard can be adopted for the quality control of Qiqilian capsule.
