In vitro antioxidant activity and potential inhibitory action against α-glucosidase of polysaccharides from fruit peel of tea (Camellia sinensis L.)

Abstract: Abstract:The conditions for extracting polysaccharides from tea (Camellia sinensis L.) fruit peel (TFPPs) were studied. Three parameters (temperature, time, and liquid/solid ratio) affecting the extraction of TFPP were optimized using response surface methodology (RSM). Under the optimized conditions, the yield of TFPP was predicted to be 4.98%. The physicochemical properties, in vitro antioxidant activities, and inhibitory effects on α-glucosidase of fractionated TFPPs (TFPP-0, TFPP-20, TFPP-40, and TFPP-60) … Show more

“…Theaflavins, a major component in black tea and oolong tea extracts, have been shown to inhibit -glucosidase activity. 20 Polysaccharides also had excellent inhibitory potential against -glucosidase 21 and the polysaccharide contents were in the order of oolong tea > black tea > green tea. 22 Therefore, oolong tea had the best inhibitory potential against -glucosidase.…”
