Abstract:
OBJECTIVE:To establish the quality standard for Gentiana scabra dispensing granule. METHODS:TLC was ad-opted to identify G. scabra in the preparation;HPLC was adopted to determine the content of gentiopicroside in the preparation:the column was Dionex C18 with mobile phase of methanol- water(25∶75,V/V)at a flow rate of 1.0 ml/min,the detection wave-length was 270 nm,column temperature was 30 ℃,the injection volume was 10 μl. RESULTS:TLC showed clear spots and good separation. The linear range of gentiopicroside injection volume was 0.302 6-3.026 μg (r=0.999 9);RSDs of precision,stability and reproducibility tests were lower than 2%;recovery was 98.27%-99.56%(RSD=0.68%,n=6). CONCLUSIONS:The estab-lished standard can be used for the quality control of Gentiana scabra dispensing granule.
