[Objective]To establish a method to determine the contents of glucase and fructose in extracts of leaves of Lonicera hypoglauca Miq. using HPLC-ELSD, and apply this method to study the content change of glucose and fructose in different solvents extracts in leaves of Lonicera hypoglauca Miq. [Methods] The chromatographic separation was achieved on Lichrospher NH2 column using a mobile phase composed of a mixture of acetonitrile and water(90:10) at a flow rate of 0.8mL·min-1 and the column temperature was 25℃.The ELSD drift tube temperature was set at 70℃ and the carrying gas was N2 and the flow rate of the gas was 1.6L·min-1. [Results] Glucose and fructose from extracts of the leaves of Lonicera hypoglauca Miq. could be wel separated, and the linearity ranges of glucose and fructose were shown at the concentration of 0.5840~1.168mg·mL-1 and 0.8256~1.8576mg·mL-1, the average recovery rate of glucose and fructose were 96.88%(RSD=1.11%) and 97.55%(RSD=1.15%), the stability of glucose and fructose was 2.12%and 0.38%, and the repeatability was 1.31% and 0.24%. Among the water extract,50% alcohol extract and 95% alcohol extract,the content of the glucose and fructose in the water extract was highest,which was 2.19mg·mL and 4.10mg·mL-1, the 50% alcohol extract was second, which was 1.13mg·mL-1 and 2.12mg·mL-1, and the 95% alcohol extract was lowest, which was 0.45mg·mL-1 and 0.65mg·mL-1.[Conclusion] The method is simple, accurate and has good repeatability, and can be used to determine the contents of glucose and fructose in the extract of leaves of Lonicera hypoglauca Miq. In this batch of leaves of Lonicera hypoglauca Miq., the contents of fructose and glucose were of water extract>50%ethanol extract>95%ethanol extract.
