Abstract:
AIM The content of baicalin in Scutellalria baicalensis Georgi. in the different parts was determined by RP-HPLC. METHODS The mobile phase was a mixed liquid with MeOH-Water-H3PO4(60∶40∶0.2). Standard curve showed a linearity within the range of 0.36～0.84 μg/ml(r=0.9995), the average recovery was 99.28%, and RSD=1.4%(n=5). RESULTS The results showed that the content of baicalin is highest in the bark (cortex) part of Scutellalria baicalensis Georgi.
