The 70% ethanolic extracts from eight neglected fruits; , , , , , , and were evaluated for their 2,2-diphenyl-1-picrylhydrazyl (DPPH) free radical scavenging, α-glucosidase inhibitory activities as well as total phenolic content. The results of this study revealed that fruit extract demonstrated the most potent radical scavenging activity. Among the fruits examined for α-glucosidase inhibitory activity, and exhibited strong activity with no significant difference. The Pearson correlation indicated that the activities of and contributed by phenolic compounds. A total of 65 metabolites were tentatively identified by using ultra-high-performance liquid chromatography tandem mass spectrometry (UHLPC-MS/MS). These findings suggested that the possible application of and as a functional food with antioxidant and α-glucosidase inhibitory properties.
