ABSTRACT
OBJECTIVE:
To establish the quality standard for Chaige ganmao mixture.METHODS:
TLC was conducted to iden-tify the Scutellaria baicalensis and Paeonia lactiflora;HPLC was conducted to determine the content of puerarin. The column was Zorbax Eclipse XDB-C18 with mobile phase of methanol-water(2575,V/V)at flow rate of 1.0 ml/min,detection wavelength was 250 nm,and column temperature was 25℃,and the injection volume was 5μl.RESULTS:
TLC showed clear spots and good sepa-ration. The linear range of puerarin was 18-198 μg/ml(r=0.999 9);RSDs of precision,stability and reproducibility tests were low-er than 2%,recovery was 99.04%-99.75%(RSD=0.28%,n=6).CONCLUSIONS:
The standard can be used for the quality con-trol of Chaige ganmao mixture.
