| Summary: | 碩士 === 東海大學 === 食品科學系 === 104 === In Taiwan, there are three new varieties of pigeon pea with high productivity and quality have been successfully bred, named Pigeon Pea Taitung 1, 2, and 3 respectively. In the previous papers, pigeon pea has potential benifit in the treatment of type II diabetes. Nevertheless, the active components of the antidiabetic activities in pigeon pea have not yet been fully documented. Hence the purpose of this study was to evaluate the antioxidant activities as well as type II diabetes relating enzymes inhibitory activity α-amylase, α-glucosidase and aldose reductase) and advanced glycation end-products (AGEs) formation inhibitory capacity of the Pigeon Pea Taitung 1, 2 and 3. The results showed that Pigeon Pea Taitung 3 had the highest total phenolics contents, total flavonoid contents, total antioxidant activity, and type II diabetes relating enzymes inhibitory activities among the three pigeon pea species. Furthermore, the effects of germination time 0-11 days of Pigeon Pea Taitung 3 on α-glucosidase, aldose reductase and AGEs were also investigated. The result indicated that the 7th day of germination for Taitung 3 Pigeon Pea had significantly higher inhibitory activities of type II diabetes relating enzymes than the other germination time. According to HPLC analysis, cyanidin-3-glucoside with the amount of 5.04 mg/g extract was the major flavonoid at the 7th day of germination for Taitung 3 Pigeon Pea.
