Abstract : Mango (Mangifera indica L.) is one of the most important tropical plants. Most studies on the exploitation of mango have been dealing with mango peels, juices and stem bark, however a little attention has been given to mango leaves. The main objective of this study was to develop a commercially phenolic-enriched product from mango leaves to be used as a nutritional supplement or as herbal tea. In this study, contents of total phenolics and total flavonoids were determined in ethyl acetate fraction prepared from mango leaves and were measured as 386.3 and 127.3 mg gallic acid and rutin equivalents per gram of extract, respectively. By using GC-MS, eight phenolic compounds including benzoic acid, pyrogallol, p-hydroxybenzoic acid, vanillic acid, syringic acid, ferulic acid, ethyl gallate and gallic acid were detected in the EtOAc fraction. It was concluded that mango leaves contain high amounts of total phenolics and flavonoids that assess the possibility to utilize mango leaves as a natural source for phenolic compounds in food and beverage industry.
