Abstract

Objective The standard for the quality control of Qiangjing capsule was studied. Method The presence of Epimedium brevicornum Maxim, Radix astragali, Radix angelicae, Sinensis were identified by TLC. The content of adenosine, the main active principle in the capsule was assayed by HPLC. Results Linearity was found in the range of 0.16～0.80 μg. The average recovery is 98.5% and RSD=1.88%. Conclusion The method was found to be highly sensitive, simple, precise and reproducible. It can be used for the quality control.
