Methods for Determination of Content in Quality Standard of Mongolian Medicine Powder of Menggenqiaoji
Abstract:Objective:To establish a method for the determinations of quercetin,isorhamnetin and catechin in mongolian medicine preparation Menggenqiaoji.Methods:A Diamonsil-C18(250 mm×4.6 mm,5 μm)column was used with the mobile phase of methanol-0.4 % phosphoric(47∶53),the flow rate was 1.0 mL·min-1,detecting wavelength 370 nm,the column temperature 25 ℃ for the determination of quercetin and isomarin.A Agilent ZORBAX-C18(250 mm×4.6 mm,5 μm)column was used with the mobile phase A of acetonitrile-acetic acid-0.03 mol·L-1 ethylenediamine tetra acetic acid-water(9∶2∶0.2∶88.8),the mobile phase B being acetonitrile-acetic acid-0.03 mol·L-1ethylenediamine tetra acetic acid-water(80∶2∶0.2∶17.8)with gradient elution,the flow rate was 1.0 mL·min-1,detecting wavelength 278 nm,the column temperature 35 ℃ for the determination of catechin.Results:The linear response ranged from 0.283 8-1.419 1 μg,0.280 9-1.404 6 μg and 0.115 5-1.155 5 μg(r= 0.999,n=6)of quercetin,isorhamnetin and catechin,the average recoveries(n=9)of the methods were 92.05 %,94.00 % and 91.25% with RSD 0.69%,0.96% and 0.71%,respectively.Conclusion:The methods are quick,accurate,reproducible and stable,and can be used for the quality control of Mongolian medicine preparation Menggenqiaoji.
