Background: Different parts of wild fruit varieties grown in North East India have a diverse range of functional components that impart several health benefits. With a focus to stimulate maximum utilization of fruit crops, the aim of the research work was to estimate the composition of phytochemicals, screen functional compounds, and determine the biological properties of pulp and peel extracts of Docynia indica. Materials and methods: Phytochemicals were quantified using standard methods. Antioxidant activity was analyzed using DPPH, Fe3+ reducing and phosphomolybdenum reduction method. Antibacterial activity was determined using a well diffusion assay against 6 bacterial strains. Active compounds were identified using GC-MS. Results: Peel extract exhibited remarkable antioxidant activity. Polyphenols function as oxidizing and reducing agents. Peel extract had a higher concentration of phenol and flavonoid. TPC was 313.35±4.03μg/mg GAE and TFC was 121.55±3.66μg/mg QE. Compounds such as coumarin, phenols, fatty acids, pyrazole, flavone and flavone derivates were identified in peel extract. On comparing the results of antibacterial activity, the pulp extract possessed a stronger ability to inhibit the growth of pathogenic bacteria. Maximum inhibition was observed for Staphylococcus aureus with a ZOI of 29 mm at 625µg/mL. Conclusion: The study supports the likelihood of using wild edible fruits as potential functional foods. Furthermore, the peels of wild edible fruits can be efficiently utilized as a natural antioxidant and antimicrobial agents.
