dc.description.abstractThe bark exudates of Lannea coromandelica and Mangifera indica are rich sources of health beneficial bioactive compounds. The bark extractions of these plants have been consumed and used in the traditional medicine for centuries. The objective of the present study was to investigate the total phenolic content and antioxidant capacity of the gum exudates of Lannea coromandelica and Mangifera indica and to evaluate the variation of physicochemical characteristics of a moderate respiratory fruit after applying the waxes. The application of these bark exudates for the food industry to develop a nutraceutical and functional fruit coating is promising. The waxes were prepared by dissolving 6 g of the exudates in 100 mL of water at 60 °C and then evaporating water to get the final volume of the wax to 40 mL. The waxes were further enhanced by adding Neem extract to the waxes. Antioxidant capacity was determined using the free radical 2, 2- diphenyl- 1- picrylhydrazyl (DPPH) method, the total phenolic contents were measured using Folin-Ciocalteu reagent assay. DPPH radical scavenging assay: 1050 value for gum exudates of Lannea coromandelica was 9.327±0.286 mg of Gallic acid equivalents per mL, IC50 value for gum exudates of Mangifera indica was 2.375±0.413 mg of Gallic acid equivalents per mL. Total phenolic contents in gum exudates of Lannea coromandelica and Mangifera indica were 6.49±1.88 ppm and 242.7 ± 34.2 ppm respectively. The gum exudates of Mangifera indica contained more antioxidants and phenols when compared to the gum exudates of Lannea coromandelica. Therefore, natural bark exudates of these plants can be recommended as a functional coating for low respiratory fruits.en_US
