ABSTRACT
AIM:
To establish method of determing baicalin,chlorogenic acid and chlorpheniramine maleate in Cang'ebiyan Tablets(Fructus Xanthii,Herba Cemtipedae,Radix Astragali,Flos Chrysanthemi indici,etc).METHODS:
The VP-ODS C_(18) column(4.6 mm?250 mm,5 ?m) was used with a mobile phase of acetonitrile-0.4%H_3PO_4 0-9 min(14∶86),9-20 min(28∶72) gradient elution,the wavelength of detector was set at 0-9 min 327 nm for determining chlorogenic acid content,9-20 min 280 nm for determining baicalin.The VP-ODS C_(18) column(4.6 mm?250 mm,5 ?m) was used with a mobile phase of acetonitrile-0.5% sodium dodecylsulfate-H_3PO_4,the wavelength of detector was set at 262 nm for determining chlorpheniramine maleate.RESULTS:
The calibration curves were linear in the range of 0.21-3.14 ?g/mL(r=0.999 9) for baicalin,in the range of(0.05-0.81 ?g/mL)(r=0.999 9) for chlorogenic acid,in the range of 0.10-1.57 ?g/mL(r=0.999 9) for chlorpheniramine maleate,respectively.The average recoveries were 102.44%,RSD=0.57%(n=6);(98.68%,)RSD=0.30%(n=6);99.46%,RSD=0.70%(n=6),respectively.CONCLUSION:
The method is simple,realizable and reproducible and can be used effectively for the quality control of Cang'ebiyan Tablets.
