Nephelium lappaceum cv. ‘Sri-Chompoo’ (rambutan) fruit showing different colors at four different maturity stages were collected: green-yellow, orange-yellow, orange-pink, and red-pink rind. At harvest and during post-harvest storage at 25°C for 6 days, the glucose, fructose and sucrose contents in the arils of rambutan fruit of different maturity stages were investigated using high performance liquid chromatography and invertase activity was also determined. At harvest, glucose was the most abundant sugar in ‘Sri-Chompoo’ rambutan fruit except at the red-pink stage in which sucrose was the dominant sugar. During post-harvest storage of fruit from four stages of maturity, glucose content decreased slightly while fructose content increased during the first 4 days of storage in green-yellow and orange-yellow fruit. Orange-pink and red-pink fruit had a nearly similar trend of glucose and fructose contents which did not differ much from that at harvest. Besides, during storage changes in sugar components in the fruit of different maturity stages were not directly related with those in invertase activity.
