Study on quality standard for Compound Xiaojingtong Capsules

AIM: The quality standard for Compound Xiaojingtong Capsule(Radix Astragali, Radix Ginseng, Radix Angelicae Sinensis, Rhizoma Chuanxiong, etc.) were studied. METHODS: The TLC method for identification of Radix Ginseng, Radix Angelicae Sinensis, Rhizoma Chuanxiong in these capsules were established. Astragaloside Ⅳ was determined by single wavelength TLC-scanning(λ s=530nm). RESULTS: Radix Angelicae Sinensis, Rhizoma Chuanxiong and Radix Ginseng could be detected. Astragaloside Ⅳ showed a linear relationship at the concentration range of 1.1～5.5μg (r=0.9983). The average recovery was 100.1% and RSD was 1.59% (n=6). CONCLUSION: This method is suitable for the quality control of Compound Xiaojingtong Capsule.
