Objective:To study the quality standard for Tianqi Capsule (Rhodiola kirilowii, Radix Astragali, etc.). Methods: Radix Astragali in Tianqi Capsule was identified by TLC and salidroside in Tianqi Capsule was determined by HPLC. Results: The linear relationship was at the range of 0.4μg ～ 0.2μg . The average recovery was 98.03%. Conclusions: The methods are available with a good reproducibility and can control the quality of Tianqi Capsule effectively.
