Abstract

Object To develop a method for the determination of scutellarin in Erigeron breviscapus (Vant.) Hand. -Mazz. and its extract (dengzhanhuasu) by capillary electrophoresis. Methods Separation was carried out in an uncoated fused silica capillary 57 cm ×50 μm (ID). Meanwhile, a running voltage 20 kV, 40 mmol/L borax (pH 8.50 with H 3PO 4) buffer and a UV detector at 280 nm were adopted. Results The calibration curve showed good linearity over the range of 0.1-4.0 mg/mL (r=0.998 5). The average recovery was higher than 98.0%. Conclusion The method is proved to be simple, rapid and accurate, and can be used for quality control of E. breviscapus and its extract (dengzhanhuasu).
