Thus, quantitative and qualitative analysis of the petroleum ether fraction was conducted by GC-MS. Among identified components, four unsaturated fatty acids had never been reported in natural products before, together with 19 known components. In addition, 17 compounds were isolated and elucidated from other active fractions. Compounds 2, 9, 15, and 17 were isolated for the first time from Mangifera genus. Compounds 1 and 2 exhibited prominent DPPH radical scavenging and \u03b1-glucosidase inhibitory effects. In order to further explore their mechanism of \u03b1-glucosidase inhibition, their enzyme kinetics and in silico modeling experiments were performed. The results indicated that 1 inhibited \u03b1-glucosidase in a noncompetitive manner, whereas 2 acted in a competitive manner. In molecular docking, the stability of binding was enhanced by \u03c0-\u03c0 T-shaped, \u03c0-alkyl, \u03c0-\u03c0 stacked, hydrogen bond, and electrostatic interactions. Thus, compounds 1 and 2 were determined to be new potent antioxidant and \u03b1-glucosidase inhibitors for preventing food oxidation and enhancing hypoglycemic activity.<\/jats:p>","DOI":"10.1155\/2020\/8858578","type":"journal-article","created":{"date-parts":[[2020,12,29]],"date-time":"2020-12-29T16:35:08Z","timestamp":1609259708000},"page":"1-15","source":"Crossref","is-referenced-by-count":15,"title":["Antioxidant
