ABSTRACT
<p><b>OBJECTIVE</b>To develop a quantitative method for the determination of four flavonoids in buds of Herba Artemisiae Scopariae.</p><p><b>METHOD</b>The sample was extracted by ultrasonic with ethyl acetate for 30 minutes and separated on kromasil ODS column with mobile phase of acetonitrile-tetrahydrofuran-1% acetic acid solution (2.5:21.5:76) and detection wavelength was 347 nm.</p><p><b>RESULT</b>The arcapillin, cirsiliol, cirsimaritin and cirsilineol in bud extract were well separated by this method. Linearities of arcapillin, cirsiliol, cirsimaritin and cirsilineol were good (r = 0.9992, 0.9999, 0.9997, 0.9997) in ranges of 0.035-0.56, 0.043-0.69, 0.040-0.64 and 0.040-0.64 microg, respectively. The average recoveries were 96.8%, 97.3%, 96.8%, 98.5% and RSD the values of repeatability were 2.5%, 3.0%, 1.5%, 3.2%, respectively.</p><p><b>CONCLUSION</b>The method validation data indicated that the method is reliable and it can be used for quality control of Herba Artemisiae Scopariae and its preparations.</p>
