Objective: To establish quality standard of Maxing Qinlong mixtures. Method: TLC was used to qualitative identification of Ephedra sinica
Scutellaria baicalensis
Pheretima aspergillum
Glycyrrhiza uralensis in Maxing Qinlong mixtures;The content of baicalin in Maxing Qinlong mixtures was determined by HPLC. Result: TLC showed specific
negative non-interference;The regression equation of baicalin was Y=1.552 3×106X+9.428 6 (r=0.999 9) with the linear range of 0.115 2-0.806 4 μg
and the average recovery was 98.6% (RSD 1.44%). Conclusion: This method was convenient
accurate with higher sensitivity
it could be used for controlling quality of Maxing Qinlong mixtures.
