To clarify the postprandial glucose suppression effect of flavonoids, the inhibitory effects of catechins and theaflavins against alpha-glucosidase (AGH) were examined in this study. It was initially demonstrated that theaflavins and catechins preferentially inhibited maltase rather than sucrase in an immobilized AGH inhibitory assay system. For the maltase inhibitory effects of theaflavins, the effects were observed in descending order of potency of theaflavin (TF)-3-O-gallate (Gal) > TF-3,3… Expand
Enzymatic Preparation of Methylated Theaflavins and their Antioxidant Activities
We investigated the antioxidant activities of two methylated theaflavins, theaflavin 3-O-(3-O-methyl) gallate (TF3MeG) and theaflavin 3-O-(3-O-methyl)gallate 3 -O-gallate (TF3MeG3 G), which wereExpand
Comparative evaluation of quercetin, isoquercetin and rutin as inhibitors of alpha-glucosidase.
The results indicated that Que, Iso and Rut could bind alpha-glucosidase to form a new complex, which exhibited a strong static fluorescence quenching via nonradiation energy transfer, and an obvious blue shift of maximum fluorescence, which would be significant for the development of more powerful antidiabetes drugs and efficacious utilization of tartary buckwheat.

In vitro and in vivo antihyperglycemic effect of 2 amadori rearrangement compounds, arginyl-fructose and arginyl-fructosyl-glucose.
Results indicate that AF and AFG, Maillard reaction products, may have antidiabetic effect by suppressing carbohydrate absorption in the gastrointestinal level, and thereby reducing the postprandial increase of blood glucose. Expand
Caffeic and chlorogenic acids inhibit key enzymes linked to type 2 diabetes (in vitro): a comparative study
The esterification of caffeic acid with quinic acid, producing chlorogenic acid, reduces their ability to inhibit α-amylase and α-glucosidase activities, which could be part of the possible mechanism by which the phenolic acids exert their antidiabetic effects. Expand
Antidiabetic potential of Asparagus racemosus Willd leaf extracts through inhibition of α-amylase and α-glucosidase
The significant inhibitory effect of α-amylase and α - glucosidase enzyme and exhibited lower inhibitory activity than acarbose was extracted by the ethyl acetate and aqueous extracts of the plant. Expand
In vitro α-glucosidase inhibitory activity of isolated fractions from water extract of Qingzhuan dark tea
Results indicated that Qingzhuan tea extracts exerted potent inhibitory effects against α-glucosidase, EGCG and ECG were likely responsible for the inhibitory activity in Qingzh Chinese dark tea. Expand
An alpha-glucosidase inhibitory activity of thermostable lectin protein from Archidendron jiringa Nielsen seeds
Inhibitors of α-glucosidase from natural resources that inhibit the digestion of carbohydrate polymers into monosaccharides in the gut are used in the treatment of insulin-independent diabetesExpand
Catechins play key role in green tea extract–induced postprandial hypoglycemic potential in vitro
Green tea is often associated with glycemic control benefit. However, the available evidence is not conclusive. In this study, we systematically assessed the contribution of main green tea extractExpand
In vitro antidiabetic potential of the fruits of Crataegus pinnatifida
The results suggest that the fruits of C. pinnatifida and its constituents have potential antidiabetic activity which might be used as a functional food for the treatment of diabetes and associated complications. Expand
