Objective To determine the content of ursolic acid and oleanolic acid in Xiakucao(Spica Prunellae) produced from different areas.Methods The HPLC procedure was performed on the chromatographic column of Diamonsil C18(4.6 mm×250 mm,5 μm),and the mobile phase was methanol-0.5% phosphoric acid solution(86∶ 14) in gradient elution.The flow velocity was 1.0 mL/min,the detection wavelength was 210 nm and the temperature was 35 ℃.Results Ursolic acid showed a good linear relationship with peak area at…
