8(250 mm×4.6 mm
5 μm)column eluted with a mobile phase of methanal-water containing 0.2% phosphoric acid solution(V∶V=85∶15).The flow rate was 1.0 mL·min-1 and column temperature was 35 ℃.The detection wavelength was set at 254 nm.Results: The calibration curve was linear within the range of 1.012 5~16.2
1.025~16.4
1.025~16.4
1.025~16.4 and 0.625~10 μg for aloe-emodin
