In recent years, there has been an ever-increasing interest in the research of polyphenols obtained from dietary sources, and their antioxidative properties. The purpose of this study was to determine the effect of boiling buckwheat and barley groats on the antioxidant properties and dietary fiber composition. Antioxidative properties were investigated using methyl linoleate model system, by as...

Ma Lin, Fan Ye, Fang Yun* (MOE Key Laboratory of Food Colloids and Biotechnology, School of Chemical & Material Engineering, Jiangnan University, Wuxi, Jiangsu 214122, China) Abstract: Conjugated linoleic acids (CLAs) are a group of positional and geometrical isomers of conjugated octadecadienoic acids, which are naturally unsaturated fatty acid with conjugated double bonds. CLAs have been wide...

Ellagitannins from red raspberries (Rubus idaeus) and cloudberries (Rubus chamaemorus) were isolated by using column chromatography and preparative HPLC. The berry phenolic isolates consisted of 80% (cloudberry) and of 60% (raspberry) of ellagitannins, with raspberries also containing anthocyanins. The main ellagitannins of both raspberries and cloudberries were identified by ESI-MS to consist ...

Essential fatty acid deficiency has been widely studied but the extent to which its effects are attributable specifically to deficiency of linoleate as opposed to deficiency of all unsaturated fatty acids is unknown. Our objective was to evaluate the effect of pure linoleate deficiency on growth as well as changes in the metabolism and oxidation of n-6 polyunsaturates. The diets contained 20 en...

Abstract Mango stem bark extracts (MSBE) have been used as bioactive ingredients for nutraceutical, cosmeceutical, and pharmaceutical formulations due to their antioxidant, anti-inflammatory, analgesic effects. We performed the MSBE preparative column liquid chromatography, which led resolution identification by GC-MS of 64 volatile compounds: 7 hydrocarbons, 3 alcohols, 1 ether, aldehydes/keto...

This study examines the effect of UV irradiation on yield and physical characteristics biodiesel from candlenut oil using a TiO 2 -K O/natural zeolite composite. Natural was activated with KOH impregnated . The formed composite analyzed an X-ray diffractometer. Biodiesel synthesized to methanol molar ratio catalyst loading (w/w oil) 1:4, 1:6, 1:8, 2, 4, 6%, respectively. XRD analysis shows peak...
