Abstract:

Some artificially synthesized anti-diabetic drugs are frequently found in health products to enhance their curative efficacy. Based on the specific recognition characteristics of molecularly imprinted technology, two kinds of molecularly imprinted composite membranes were prepared with dummy template of guanidine hydrochloride and 4-(2-aminoethyl)-benzene sulfonamide. The adsorption capacities of these two membranes to metformin hydrochloride, phenformin hydrochloride and glibenclamide were studied. Meanwhile, surface enhancement Raman spectrometry(SERS) to determine the target chemicals was established and employed in the membrane detection after infiltrated in the health products extract solution. The influence of nano-silver particles on the membrane to SERS was also studied. The detection limits of metformin hydrochloride, phenformin hydrochloride and glibenclamide are 5, 5 and 10 mg/mL, respectively. This method was also proved by several pieces of real samples.
