Journal ArticleDOI
Phenolic profiles of 20 Canadian lentil cultivars and their contribution to antioxidant activity and inhibitory effects on α-glucosidase and pancreatic lipase.
Bing Zhang,Zeyuan Deng,D. Dan Ramdath,Yao Tang,Peter X. Chen,Ronghua Liu,Qiang Liu,Rong Tsao +7 more
TL;DR: It was the flavonols, not the flavanols, which showed the inhibitory activities against α-glucosidase and pancreatic lipase, thus contributing significantly to the control of blood glucose levels and obesity.
Journal ArticleDOI
Characterisation of phenolics, betanins and antioxidant activities in seeds of three Chenopodium quinoa Willd. genotypes.
TL;DR: Findings of these phenolics, along with betacyanins in this study add new knowledge to the functional components of quinoa seeds of different cultivar background.
Journal ArticleDOI
Characterisation of fatty acid, carotenoid, tocopherol/tocotrienol compositions and antioxidant activities in seeds of three Chenopodium quinoa Willd. genotypes.
Yao Tang,Xihong Li,Peter X. Chen,Bing Zhang,Marta Hernandez,Hua Zhang,Massimo F. Marcone,Ronghua Liu,Rong Tsao +8 more
TL;DR: The antioxidant activities of lipophilic extracts were positively correlated with polyunsaturated fatty acids, total carotenoids and total tocopherols, and the concentration of zeaxanthin was also the highest in black seeds.
Journal ArticleDOI
Bound Phenolics of Quinoa Seeds Released by Acid, Alkaline, and Enzymatic Treatments and Their Antioxidant and α-Glucosidase and Pancreatic Lipase Inhibitory Effects.
Yao Tang,Yao Tang,Bing Zhang,Bing Zhang,Xihong Li,Peter X. Chen,Peter X. Chen,Hua Zhang,Ronghua Liu,Rong Tsao +9 more
TL;DR: Carohydrases, that is, pectinase, xylanase and feruloyl esterase, which effectively liberated bound phenolics are known to be secreted by colonic bacteria, suggesting potential antioxidant and anti-inflammatory effects by these compounds in the large intestine during colonic fermentation.
Journal ArticleDOI
Characterization of free, conjugated and bound phenolics and lipophilic antioxidants in regular- and non-darkening cranberry beans (Phaseolus vulgaris L.)
TL;DR: Results from this study can contribute to the development of cranberry bean cultivars with increased health benefits and addresses specific phenolic contributors to antioxidant activity.
