A rapid and simple method for the determination of scutellarin and rutin in Shenfukang capsules has been developed using reversed-phase high performance liquid chromatography. Scutellarin and rutin were first extracted by ultrasonic extraction with methanol-water (1:1, v/v). The resulting extracts were separated on a C18 column (4.6 mm i.d. x 150 mm, 5 microm). The mobile phase consisting of 0.02 mol/L KH2PO4 solution containing 1.0% glacial acetic acid-methanol (63:37, v/v) was run at a flow rate of 1.0 mL/min. The detection wavelength was 330 nm and the injection volume was 20 microL. Good linearity in the range of 10 mg/L to 300 mg/L was obtained for scutellarin and rutin. The method was successfully used for the quantification of scutellarin and rutin of Shenfukang capsules.
