Elateriospermum tapos contains high unsaturated fat and phytochemicals with many health benefits. This paper focuses on activities and inhibitory effects of E. tapos on digestive enzymes. Cold water, hot water and 70% ethanol extracts of the seed and shell of the fruit of E. tapos were used in this study. The extracts were screened for antioxidant activity, total phenolic content, total flavonoid content, and inhibitory effects on α-amylase, α-glucosidase and pancreatic lipase. Hot water extraction of shell of the E. tapos fruit had the highest total phenolic content (1298.60 ± 4. 24 μg GAE 100 g⁻¹), total flavonoid content (16685.58 ± 487.77 μg CE 100 g⁻¹) and antioxidant activity by 2, 2-diphenyl-2-picrylhydrazyl and β-carotene methods (84.16 and 122.17% respectively). The seed cold extract showed maximum α-amylase inhibition with IC₅₀ (half maximal inhibitory concentration) of 0.03 mg mL⁻¹. The lowest IC₅₀ (0.02 …
