    The number of diabetic patients is increasing especially in Asia according to change of life habits (1). In mild case of diabetes, many patients are left without medical treatments and the long period of none treatment causes serious complications that impair the quality of life of the patients (2). Diabetes is a chronic disease that is characterized by hyperglycemia caused by insufficiency of the insulin action (3). So, we considered that edible ingredients which can complement insulin action are useful to prevent and cure diabetes and complications associated with the disease.
    We tried to find the insulin mimic compounds from edible plants. We investigated the two insulin mimic activities of edible plant materials; (a) adipocyte differentiation activity and (b) enhancement activity of glucose uptake, using pre-adipocyte cell line 3T3-L1 (4,5). As a result, we found that ethanol extract of Angelica keiskei, a dropwort indigenous to Japan and called “Ashitaba”, has both activities (6). We tried to isolate active compounds from the extract, and we found that two major chalcons peculiar to Angelica keiskei, xanthoangelol (XA) and 4-hydroxyderricin (4HD) have both activities (a) and (b). Regarding adipocyte differentiation, XA and 4HD have the similar level of activities. On the other hand, regarding enhancement of glucose uptake, the activity of 4HD is several times as high as that of XA. Furthermore, the combination of XA and 4HD could complement insulin action (induction of adipocyte differentia ... 전체 초록 보기
