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 mg/mL 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 mg/mL 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 mg/mL concentration. These results suggest that the selected extracts could be potentially used as a resource of bioactive materials for health functional foods. Source

In this study, we investigated the anti-obesity activity of Aceriphyllum rossii ethanol extract on rat fed a high fat diet. Male SD rats were divided into four groups. Group 1 was the control. Group 2 was fed a high-fat diet. Group 3 was the positive control, fed a high-fat diet supplemented with Garcinia Cambogia extracts. Group 4 was fed a high fat diet supplemented with ethanol extracts of Aceriphyllum rossii (EEAR). Precisely 166 mg/kg of powdered Garcinia Cambogia extracts was used for Group 3. Also, 250 mg/kg of EEAR was used for Group 4. The Body weight increased Group 2, but decreased Group 4. The serum total cholesterol in Group 2 increased by 15.26% when compared to Group 1, but only increased 5.29% in Group 3 and 4.29% in Group 4. The liver and mesenteric adipose tissue weights of Group 2 increased compared to Group 1, whereas they decreased in Group 3 and Group 4. As a result of measuring the concentration of triglycerides in extracted livers, Group 2 showed a significant increase compared to the Group 1, and Groups 3 and 4 showed significant decrease compared Group 2. These results suggest that Aceriphyllum rossii ethanol extracts may be useful as an anti-obesity agent. Source

This study investigated the physiochemical characteristics of Xanthoceras sorbifolia seed oil. Xanthoceras sorbifolia seed oil was extracted by supercritical fluid extraction (420 atm, 50°C), hexane extraction and heatpressed extraction (160°C, 180°C). Acid values and peroxide values were evaluated, as well as the degree of lipid oxidation. The heat-pressed (160°C) extraction gave a 53.5±2.5% higher yield of oil, compared with the other extraction methods. The acid values from the super critical fluid extraction were the highest, while peroxide values were highest from the heat-pressed extraction at 160°C (3.10 meq/kg). The contents of linolenic acid and oleic acid were 38.63~41.13% and 26.29~26.85%, respectively. Contents of stigmasterol and β-sitosterol were 6.01~6.49 mg/100 g and 58.19~59.85 mg/100 g, respectively. These results indicate that Xanthoceras sorbifolia seed oil can possibly serve as new edible oils. Source
