Abstract: This study discussed the method for determination of fructose, glucose, sucrose and maltose content in honey by reverse-phase high performance liquid chromatogram refractive index detector (HPLC-RID). Results indicated that not only the carbohydrate can be extracted from the honey effectively, but also the mobile phase relative coherence can be guaranteed by dissolving sample (2.5 g) with distilled water (30 ml) and then diluting to 50 ml with acetonitrile. Soluble mechanism was also presumed. The excellent stability and repeatability are obtained by the developed pretreatment method. The spiked recoveris is in the range of 97%～103% with relative standard deviation of 0.8%～1.6%. Eight different honey samples were detected and good results are obtained.
