Type 2 diabetes mellitus (T2DM), a worldwide disease that affects the quality of human life and social development. Glucose, fructose and 1,5-anhydroglucitol are closely related to diabetes mellitus. However, few methods have been reported to achieve these three carbohydrates in the blood simultaneously. In this study, a UPLC-MS/MS method allowing to quantify glucose, fructose, and 1,5-anhydroglucitol simultaneously in human plasma was developed. The analysis was performed by UPLC-MS/MS system with HILIC column. This new method provided satisfactory results in terms of calibration curves with good linearity (R2 > 0.99) over 3 order of magnitude range, precision (coefficient of variation of intra-day and inter-day: 0.72-10.23% and 2.21-13.8%), accuracy (results of intra-day and inter-day: 97-113%, 100-107%), matrix effects (87-109%), recovery (93-119%), carry-over (0.004-0.014%), as well as stability (0.04-6.9%) within the acceptance criteria. The reproducible, precise and accurate method with suitable dynamic ranges was successfully applied to the analysis of glucose, fructose and 1,5-anhydroglucitol in T2DM under different pathophysiological conditions.
