“…It is known that the hydroxyl radical is a powerful oxidant that can react with nearly all the biomacromolecules functioning in living cells (Santanam, Ramachandran, & Parthasarathy, 1998;Xie et al, 2012) and that oxidative stress can mediate a wide variety of degenerative processes and diseases (Dhalla, Temsah, & Netticadan, 2000;Sayre, Smith, & Perry, 2001). Among the reactive oxygen species, the hydroxyl radical is the most reactive and induces severe damage to adjacent biomolecules (Yuan et al, 2005).…”

In the present study, ultrasonic extraction technique (UET) is used to improve the yield of polysaccharides from Laminaria japonica (LJPs). And their antioxidative as well as glycosidase inhibitory activities are investigated. Box-Behnken design (BBD) combined with response surface methodology (RSM) is applied to optimize ultrasonic extraction for polysaccharides. The optimized conditions are obtained as extraction time at 54 min, ultrasonic power at 1050 W, extraction temperature at 80℃ and ratio of material to solvent at 1:50 (g mL −1 ). Under these optimal ultrasonic extraction conditions, an actual experimental yield (5.75% ± 0.3%) is close to the predicted result (5.67%) with no significant difference (P > 0.05). Vitro antioxidative and glycosidase inhibitory activities tests indicate that the crude polysaccharides (LJP) and two major ethanol precipitated fractions (LJP1 and LJP2) are in a concentration-dependent manner. LJP2 (30%60% ethanol precipitated polysaccharides) possesses the strongest α-glucosidase inhibitory activity and moderate scavenging activity against hydroxyl radicals (66.09% ± 2.19%, 3.0 mg mL −1 ). Also, the inhibitory activity against α-glucosidase (59.08% ± 3.79%, 5.0 mg mL −1 ) is close to that of acarbose (63.99% ± 3.27%, 5.0 mg mL −1 ). LJP1 (30% ethanol precipitated polysaccharides) exhibits the strongest scavenging activity against hydroxyl radicals (99.80% ± 0.00%, 3.0 mg mL −1 ) and moderate α-glucosidase inhibitory activity (47.76% ± 1.92%, 5.0 mg mL −1 ). LJP shows the most remarkable DPPH scavenging activity (66.20% ± 0.11%, 5.0 mg mL −1 ) but weakest α-glucosidase inhibitory activity (37.77% ± 1.30%, 5.0 mg mL −1 ). However, all these LJPs exert weak inhibitory effects against α-amylase. These results show that UET is an effective method for extracting bioactive polysaccharides from seaweed materials. LJP1 and LJP2 can be developed as a potential ingredient in hypoglycemic agents or functional food for the management of diabetes. This study provides scientific evidence and advances in the preparation technology and a hypoglycemic activities evaluation method for seaweed polysaccharides, especially glycosidase inhibition in combination with an antioxidative activity evaluation method.

“…The leaves of C. paliurus have been used to make tea in China because of its unique taste. The leaves possess several health benefits, such as antihypertensive activity, enhancement of mental efficiency and antioxidant activity (Kurihara et al, 2003;Xie et al, 2012). It is also used to inhibit inflammation and prevent hypolipidaemic and diabetes (Xie, Xie, Nie, Shen, Wang, & Li, 2010).…”
