摘要

A speedy and selective ultra-HPLC-MS/MS method for simultaneous determination of deoxynivalenol (DON), 3-acetyldeoxynivalenol (3-ADON), 15-ADON. nivalenol and fusarenon X in traditional Chinese medicines (TCMs) was developed. The method was based on one-step sample cleanup using reliable homemade cleanup cartridges. A linear gradient mobile-phase system, consisting of water containing 0.2% aqueous ammonia and acetonitrile/methanol (90:10, v/v) at a flow rate of 0.4 mL/min, and an Acquity UPLC HSS T3 column (100 mm x 2.1 mm, 1.8 mu m) were employed to obtain the best resolution of the target analytes. [C-13(15)]-DON was used as the internal standard to accomplish as accurate as possible quantitation. The established method was further validated by determining the linearity (R-2 >= 0.9990), sensitivity (LOQ, 0.29-0.99 mu g/kg), recovery (88.5-119.5%) and precision (RSD <= 15.8%). It was shown to be a suitable method for simultaneous determination of DON, 3-ADON, 15-ADON, nivalenol and fusarenon X in various TCM matrices. The utility and practical impact of the method was demonstrated using different TCM samples.
