Description
Summary:High-performance liquid chromatography (HPLC) has been evaluated for the determination of components in <i>Scutellaria baicalensis georgi</i>, primarily by the separation of baicalin. The samples were extracted at reflux by methanol, and the content of chlorogenic acid was analyzed by HPLC. A Diamonsil C18 column (4.6 mm x 150 mm, 5 μm) was used as the analytical column. The mobile phase was methanol, water and phosphoric acid (47:53:0.2). The detection wavelength was 280 nm to determine the content of baicalin. The baicalin showed linearity over the range of 0.12-1.2 &mu;g. Its average recovery was 98.6% and RSD was 0.78%.
