Abstract

|
We investigated α-amylase, α-glucosidase and lipase inhibitory activity of extracts collected from wild plants in Gangwon-do. 90 wild plants were collected and their water and ethanol extracts were obtained. Results of measuring α-amylase inhibitory activity indicated more than 80% of activity inhibition in 10 ㎎/㎖ concentration for ethanol extracts of three plants and water extracts of two plants. For α-glucosidase inhibitory activity, ethanol extracts of thirteen plants and water extracts of three plants showed more than 80% of activity inhibition in 10 ㎎/㎖ concentration. In the experiment of inhibiting lipase activity, ethanol extracts of seven plants and water extracts of one plants showed above 80% of activity inhibition in 10 ㎎/㎖ concentration. These results suggest that the selected extracts could be potentially used as a resource of bioactive materials for health functional foods.
