TLC Identification and Content Determination of Gentiopicroside in Yan Reqing Tablet
Objective:To establish the methods for TLC identification and content determination of Yan Reqing Tablet.Method: gentiopicroside in Yan Reqing Pian was identified by TLC
and the content of gentiopicroside was detected by HPLC.Result:The results indicated that the bands in the TLC were clear without interference(Rf=0.600).Gentiopicroside in the calibration curve showed good linearity in the range of 0.222 5-1.78 μg(n=5).Conclusion:This qualitative and quantitative method is simple
accurate and reproducible
which can be used for the quality control of Yan Reqing Tablet.
