ResumoThe leonurus contents in Herba Leonuri was determined by high performance liquid chromatography(HPLC),in which the mobile phase was 0.00125 mol/L KH2PO4∶CH3OH(87∶13,V/V) with a flow rate 1 mL/min and the UV detection wavelength was at 276 nm.The regression equation of the calibration curve for lenurine was y=227 394x+1 292 605(r=0.9999,n=5).The result showed that HPLC is a convenient and feasible method for determination of the alkaloid content in Yimucao.
