Simultaneous Determination of Five Components in Fufang Heishen Oral Liquid by Dual-wavelength HPLC / 医药导报

ABSTRACT

Objective To establish a method that could detect 5 components of Fufang Heishen oral liquid simultaneously. Methods The component was performed by high performance liquid chromatography ( HPLC) equipped with Agilent Hypersil ODS (4.6 mm×250 mm,5 μm).The mobile phase consisted of acetonitrile-0.1% Phosphoric acid with gradient elution.The flow rate was 1.0 mL·min-1with the 210 nm and 270 nm detection wavelength,20 μL injection volume and 30 ℃column temperature. Results A good linear relationship was observed with the range of 7.12-85.44 mg·L-1for Harpagide (r＝0.999 9),2.50-30.00 mg·L-1for Harpagoside(r＝0.999 8),25.35-304.20 mg·L-1for Cinnamic acid(r＝0.999 7),0.73-8.70 mg·L-1for Tectoridin(r＝0.999 7)and 1.20-14.40 mg·L-1for Irisflorentin(r＝0.999 8).The average recovery of each detected component of Fufang Heishen Oral Liquid was 98.8%,102.7%,98.8%,99.3%,99.9% the RSD were 1.23%,2.89%, 2.60%,1.44%,2.84%(n＝6). Conclusion The method is simple,rapid and accurate and can be used to detect the content of Harpagide,Harpagoside,Cinnamic acid,Tectoridin and Irisflorentin of Fufang Heishen Oral Liquid.
