ABSTRACT
Objective To establish a method for the simultaneous determination of new mangiferin, mangiferin, artemisinin BⅡ, icariin and artemisinin A in Anemarrhenae Rhizoma by high performance liquid chromatography-evaporation light scattering detector (HPLC-ELSD). Methods The column was Agilent Poroshell 120 EC-C18. The mobile phase used acetonitrile-0.2% acetic acid water system with gradient elution. Column temperature was 30 ℃. Flow rate was 0.7 ml/min. Evaporative light scattering detector used nitrogen as atomizing gas. The atomizing gas temperature was 40 ℃ and the drift tube temperature was 90 ℃. The nitrogen volume flow rate was 2.00 L/min and the sample volume was 20 μl. Results The five components were able to achieve baseline separation. Neomangiferin, Mangiferin, Anemaponin BⅡ, Baohuoside I , Anemarrhena saponin AⅢwere determined as 24.1-386 μg/ml (r=0.999 3), 23.2-371 μg/ml (r=0.998 6), 54.2-867.2 μg/ml(r=0.995 6), 5.3-84.8 μg/ml (r=0.996 8), 10-160 μg/ml (r=0.998 9) respectively, which showed a good linear relationship within the concentration range. The average recovery rate of the five components was between 101.8% and 105.0%, and the repeatability RSD was less than 2.4%. The content of the above five components in Zhimu medicinal materials were 1.62%, 0.82%, 7.36%, 0.07%, 0.34%, respectively. Conclusion The method is simple, accurate, and highly sensitive, which could be used as the quantitative determination of multiple index components of Anemarrhenae Rhizoma.
