| 摘 要： | 以丙烯酰胺为功能单体,葛根素为模板分子,马来松香丙烯酸乙二醇酯为交联剂,采用循环伏安法合成了葛根素分子印迹膜,并以此为识别元件制备了葛根素电化学传感器。该传感器对葛根素具有高度的选择性和良好的敏感度,葛根素氧化峰电流与其浓度在6.0×10-8～1.6×10-3mol/L范围内呈良好的线性关系,检出限为2.0×10-8mol/L。将此传感器用于葛根素注射液和木瓜葛根片中葛根素的含量测定,回收率为97.7%～106.4%。 |

| Abstract: | Using acrylamide as a functional monomer,puerarin as a template,maleic rosin acrylic acid glycol ester as the cross linking agent,molecularly imprinted polymer membrane is synthesized in solution by cyclic voltammetry.The sensor shows high selectivity and good sensitivity towards the target puerarin and it gives a linear correlation to puerarin concentration over a range from 6.0×10-8 to 1.6×10-3 mol/L with the detection limit of 2.0×10-8 mol/L.The sensor has been applied to the analysis of puerarin in puerarin injection and papaya﹠pueraria root tablet samples with recoveries ranging from 97.7% to 106.4%. |
