Screening for antidiabetic activity and phytochemical constituents of common bean (Phaseolus vulgaris L.) seeds
Seeds of Phaseolus vulgaris were given individually at different doses to different batches of rats (both normal and hyperglicemic rats) after an overnight fast. Seeds contain the bioactive components – alkaloids, flavonoids, fiber, proteins, tannins, terpenoids, saponins, quercetin, anthocyanin and catechin. The blood glucose levels were measured at 0, 1, 2, 3, 4, 5 and 6 h after the treatment. Most...
