Methods HPLC method was carried out on Zorbax SB-C18 (5 μm, 4.6 mm×250 mm), with detection wavelength at 320 nm. The mobile phase was composed of methanol-0.3% aqueous acetic acid (35∶65), the column temperature was 35 ℃ and the flow rate was 1.0 mL/min. Results The calibration curve was linear in the range of 0.031～0.310 μg (r＝0.999 9). The average recovery was 95.82% (RSD＝0.63%). Conclusion This method is si
