Abstract:Objective A fast and accurate method was developed for the determination and conformation of buformin and glibornuride illegally added in traditional Chinese medicines and health foods by ultra-performance liquid liquidtandem mass spectrometry (UHPLC-MS/MS). Methods The samples were extracted with methanol by ultrasonic processing and separated on a ACES C18 (150 mm×2.1 mm, 1.7 μm) column with 0.1% formic acid-10 mmol/L ammonium acetate (A) and acetonitrile (B) solution by gradient elution. The chemical drugs were determined by UHPLC-MS/MS in positive ionization ESI and selected reaction monitoring mode. The obtained molecularions, fragment ions, and retention time for SRM channels were used to identify the two kinds of drugs, and quantitative analysis was conducted with external standard method. Results This method had a good separation effect, the two kinds of chemical drugs, including Buformin and Glibornuride showed good linearity in the range of 50-2000 ng/mL with the correlation coefficients (r≥0.9997). The limits of detection were 0.65 μg/g and 0.56 μg/g. The recoveries were 98.06% and 97.54%, and the RSDs were 2.43% and 3.84%. Conclusion This method is simple, accurate with high sensitivity, which was suitable for rapid determination of the two kinds of chemical drugs which illegally added in traditional Chinese drugs and health foods.
