HPLC-CAD法测定口服五维赖氨酸葡萄糖中葡萄糖含量
Determination of Glucose in Oral Five-Vitamin and Lysine Glucose Preparations by HPLC-CAD
摘要
Abstract
Objective:To establish a high-performance liquid chromatography-charged aerosol detector(HPLC-CAD)method for determining the glucose content in oral five-vitamin and lysine glucose preparations,and to compare the results obtained by this method with those of the iodometric method recorded in the current quality standards.Methods:HPLC-CAD is used;the chromatographic column is Waters XBridge BEH Amide(4.6 mm ×250 mm,5 μm).The mobile phase is 0.2%triethylamine aqueous solution and acetonitrile(25∶75);the flow rate is 1.0 mL·min-1.Clumn temperature is set at 30 ℃;the injection volume is 20 μL.Results:In the system suitability solution,baseline separation was achieved between glucose and sucrose,fructose,and lactose.The linear relationship of glucose is good within the range of 0.490 8 to 0.981 6 mg·mL-1(r=0.999 6).The quantification limit of the method is 0.2 μg,and the recovery rate is 100.82%to 102.58%(RSD=0.8%,n=6).The glucose content in 96 batches of samples from 4 production enter-prises across the country was determined using HPLC-CAD and iodometry,and the results were analyzed and compared.Due to the inter-ference of excipients in the 4 enterprises on the iodometry method,the true content of glucose could not be reflected.The HPLC-CAD method resulted in a lower glucose content than the iodometry method,indicating a more accurate result.Conclusion:This method is simple to operate,exhibits good specificity and high sensitivity,and can accurately determine the glucose content in oral five-vitamin and lysine glucose preparations.关键词
