Objective To establish a HPLC method for the simultaneous determination of artemisinin,arteannuin B,chrysosplenetin and chrysosplenol-D in the water extract of Artemisia annua L.Methods The analysis was performed on Agilent ZORBAX SB-C18(250 mm×4.6 mm,5 μm)column with a mobile phase of acetonitrile(A)-water(B)and the flow rate of 0.8 mL·min-1 in a gradient elution manner.The column temperature was 30℃.The injection volume was 10 μL,and the detection wavelength was 210 nm.Results Artemisinin,arteannuin B,chrysosplenetin and chrysosplenol-D were correlated well linearly with peak area in their respective ranges 1.608 8-16.088 μg(r=0.999 9),0.014 1-0.141 4 μg(r=1),0.185 1-1.850 9 μg(r=0.999 9),0.144 1-1.441 4 μg(r=0.999 9),the average recovery rate(n=6)were 102.44%,97.82%,95.07%,95.55%,and the RSD values were 1.12%,1.44%,1.29%,1.53%.Conclusion This method is convenient and accurate.It has good stability and repeatability,and can be used to simultaneously determine the content of artemisinin,arteannuin B,chrysosplenetin and chrysosplenol-D in the water extract of Artemisia annua L.
