Hypoglycemic effect of abandoned Porphyra haitanensis polysaccharides in alloxan-induced diabetic mice
Publication date: Available online 4 June 2016 Source:Bioactive Carbohydrates and Dietary Fibre Author(s): Chunjie Cao, Meizhen Chen, Bin Liang, Jingyan Xu, Tianwen Ye, Zufeng Xia The therapeutic effects and preliminary mechanism of abandoned porphyra haitanensis polysaccharides (APHP) in diabetic mice induced by alloxan were studied in this paper. The intragastric administration of APHP for 21 days induced an obvious decrease (P<0.05) in blood glucose levels, compared with untreated diabetic mice. The data of total cholesterol (TC), total triglyceride (TG), low-density lipoprotein cholesterol (LDL),...

Identification of pivotal components on the antioxidant activity of polysaccharide extract from Ganoderma atrum
Publication date: Available online 22 April 2016 Source:Bioactive Carbohydrates and Dietary Fibre Author(s): Hui Zhang, Steve W. Cui, Shao-Ping Nie, Yi Chen, Yuan-Xing Wang, Ming-Yong Xie The pivotal components responsible for the antioxidant activities of polysaccharide from Ganoderma atrum (PSG) were identified by chemical composition and antioxidant activity analysis after separating PSG into different fractions. PSG was determined to be a mixture with neutral fraction and acidic fraction, as well as protein and phenolic compounds. The fractions with different ionic density were separated by anion exchan...

Anti-obesity effects of enzymatically-digested alginate oligomer in mice model fed a high-fat-diet
In this study, the anti-obesity effects of dietary acid-hydrolyzed (A-AO) and enzymatic-digested (E-AO) alginate oligomers were investigated in male mice fed a high-fat diet. E-AO showed stronger anti-obesity effects than A-AO, as judged by the reduction in body and adipose tissues weights. Further studies demonstrated that the anti-obesity effects of E-AO were superior to those of original alginate polymer (AP). E-AO also showed anti-obesity effects in female obese mice, in which E-AO suppressed the plasma leptin level. Dietary AP and E-AO suppressed the increase in serum triglyceride (TG) levels induced in mice by oral a...

Musa Obesity is a global health concern associated with high morbidity and mortality. Therapeutic strategies include surgery and synthetic drugs; however, these may cause severe complications and high costs. The anti-obese effects of dietary fiber have widely been accepted in literature. Gum arabic (GA, Acacia Senegal) considered as a dietary fiber that could reduce the body fat deposition, nevertheless, its anti-obese ...
