ABSTRACT

AIM: To establish the quality standard for Compound Yiqi Granules (Radix Astragali, Radix Achyranthis Bidentatae, etc.). METHODS: Radix Achyranthis Bidentatae; Herba Epimedii were identified by TLC. The content of astragaloside IV in Compound Yiqi Granules was determined by TLCS. RESULTS: The methodological study showed a good linear correlation at the range of 1.12-5.60 ?g of astragaloside IV. The average recovery of astragaloside IV was 97.69% and RSD was 2.10%, respectively. CONCLUSION: The method is simple, accurate and with good repeatability. The method can be used for quality control of Compound Yiqi Granules.
