The main use parts of the tree are fruit, stem, and leaf that can be eaten as vegetables. This study aims to (1) identify several bioactive chemical compounds in the stems and leaves of bitter melon trees in the forests in the district of Mang Yang, Gia Lai province; (2) evaluate the nutrient composition, antioxidant activity, and antimicrobial ability of fresh juice and extract with ethanol 70°. The results indicated that fresh juice and ethanol 70° extract currently inhibited the growth of experimental strains of microorganisms, in which ethanol 70o extract gives the highest antimicrobial effect. The qualitative results determined that the chemical components of wide bitter melon consist of flavonoids, saponins, tannins, free reducing sugar, organic acids, starch, and fatty acids as the basis for the standardization of exploitation of medicinal resources this material. |
