Study on the Quality Standard of Shenshuaikang Granule / 中国药房

ABSTRACT

OBJECTIVE:To establish the quality standards for Shenshuaikang granule. METHODS:TLC was used for the quali-tative identification of Astragali Radix and Rhei Radix et Rhizoma in the preparation. HPLC was used for the contents determina-tion of emodin and chrysophanol ,the column was Agilent HC-C18 with mobile phase of methanol-0.1% phosphoric acid (8515 , V/V)at a flow rate of 1.0 ml/min,the detection wavelength was 254 nm,the column temperature was 30 ℃ and the injection vol-ume was 10 μl. RESULTS:TLC showed clear spots and good separation. The linear range was 1.9-60.8 μg/ml for emodin(r=0.999 9, n=6) and 1.6-51.2 μg/ml for chrysophanol (r=0.999 9),RSDs of precision,stability and reproducibility tests were lower than 3%,recoveries were 95.76%-103.66%(RSD=2.83%,n=9)and 97.24%-104.34%(RSD=2.65%,n=9),respectively. CONCLU-SIONSThe standard can be used for the quality control of Shenshuaikang granule.
