| Research Abstract |
In order to investigate anti-diabetic constituents from medicinal foods, we examined following screening tests : (1) inhibitory effects on high glucose-induced triglyceride (TG) accumulation in HepG2 (2) effects on TG metabolism in high glucose pre-treated HepG2 (3) effects on glucose consumption in HepG2. As the results, acylated flavonol glycosides, tiliroside and helichrysoside, reduced TG contents in high glucose pre-treated HepG2 and enhanced glucose consumption in HepG2. In addition, administration of helicrysoside improved glucose tolerant in ddY mice. Furthermore, we found that isopteryxin, a khellactone-type coumarine, improved insulin-induced glucose consumption in HepG2 cells, and that neosedumoside II, a megastigmane glycoside, reduced TG contents in high glucose pre-treated HepG2.
