Determination of nine effective constituents in Chenxiang-Huaqi tablets by quantitative analysis of multi-components by single marker / 国际中医中药杂志

ABSTRACT

Objective To develop a method of quantitative analysis of multi-components by single marker for nine effective constituents in Chenxiang-Huaqi tablets. Methods Using HPLC method, the mobile phase was acetonitrile -0.2% physcion acid in gradient elution program, the flow rate was 1.0 ml/min. The detection wavelength was set at 230 nm for liquiritin, ammonium glycyrrhizinate, costunolide and dehydrocostus lactone, and 283 nm for narirutin, naringin, hesperidin and neohesperidin, and 310 nm for pogostone. The column temperature was 30 and the injection volume was 10 μl.℃ Using Hesperidin as the internal standard, the relative correction factors among liquiritin, ammonium glycyrrhizinate, costunolide, dehydrocostus lactone, narirutin, naringin, neohesperidin, pogostone were detected by QAMS and their contents were calculated. The content difference of the above nine components with the external standard method were compared. Results The calculated values of hesperidin, liquiritin, ammonium glycyrrhizinate, costunolide, dehydrocostus lactone, narirutin, naringin, neohesperidin, pogostone were not statistical significance from those measured by external standard method (P>0.05). Conclusions The method offered reference for quality standard of Chenxiang-Huaqi tablets.
