ABSTRACT
Objective:
To develop an HPLC method with solid nuclear particle chromatographic column to determine 13 anti-diabetic drugs illegally added in health food.Methods:
The analysis was performed by an HPLC system of Waters e2695, with Cortecs-C18 (100 mm × 4.6 mm, 2.7 μm) column. PDA was performed to identify and quantify tolbutamide, glibenclamide, gliclazide, glipizide, gliquidone, glimepiride, rosiglitazone, repaglinide, pioglitazone hydrochloride, metformin, phenformin, buformin hydrochloride, and glibomuride, which were extracted with methanol by ultrasonic.Results:
Thirteen linear calibration curves were obtained with r2 ≥ 0.998 7. The precision of the method was shown by RSD (n = 6) ranged from 0.6% to 1.5%. The recoveries were determined at three concentrations and ranged from 95.9% to 104.7%. The ranges of LLOQ were from 1.1 μg/mL to 3.3 μg/mL and the RSDs (n = 9) of inter-day precision were from 0.5% and 1.6%. Seventeen batches in 86 antidiabetic health foods were added the chemicals with positive rate of 20%. The glibenclamide, buformin hydrochloride, rosiglitazone, glimepiride, metformin, and pioglitazone hydrochloride were determined.Conclusion:
The method is specific, simple, and fast to detect 13 anti-diabetic drugs illegally added in health food.
