The purpose of this current research is quantitative determination of glucose, fructose and sucrose in various grapes. Grape is one of the most important commercial crops and widely consumed. Green, black and red grapes are used for present study which is easily available in the market. Simultaneous determination of sugars was performed using High performance liquid chromatography equipped with ELSD detector. The concentration of fructose and glucose ranged from 8.70-10.44% and 6.17-9.18% respectively. It was found that fructose to glucose ratio varied among variety of grapes. Red grapes contain increased concentration of glucose than fructose. Sucrose, maltose, xylose and lactose were found to be below limit of detection. Fructose and glucose are the major sugars found in all samples.
