Determination of Baicalin Content in Qingre Jiedu Granules by HPLC
Baicalin in the sample was extracted with methanol
and determined by HPLC.The chromatographic conditions were as follows:column:C18(4.6mm×250mm);mobile phase:MeoH-H2O-H3PO4(47∶53∶0.2). The linear range was 0.12~1.2μg
and the average recovery of baicalin from the samples was 99.2%,RSD=2.0%.
