Abstract:
OBJECTIVE:To establish a method for content determination of baicalin in Scutellaria baicalensis Georgi extract and to optimize the extraction technique.METHODS:The content of baicalin was adopted as index and was deter?mined by HPLC;Single factor test and orthogonal test were employed to optimize the extraction technique.RESULTS:The detected concentration of baicalin showed a good linear relation in the range of0.05912～0.02956mg/ml(r=0.99974),the average recovery was99.5%,RSD=1.10%(n=5);The optimal technique was twice recirculation in water solvent14times the amount of Scutellaria baicalensis Georgi flour,each time for1hour.CONCLUSION:The established method is conve?nient,and the extraction technique is stable,reasonable and practicable.
