15 صفحه اولTea Polyphenols – Their Antioxidant Properties and Biological Activity – a Review
Tea is the most widely consumed beverage in the world. Tea leaves are a source of polyphenols, especially catechins, a decisive group for their antioxidative activity. This paper reviews what is known of green tea species, its leaves processing and changes occurring in tea components. The main green tea polyphenols are catechins: (±)-catechin C, (-)-epicatechin EC, (+)-gallocatechin GC, (-)-epi...
متن کاملStudy on Barley and Malt Polyphenoloxidase. I. Chromatography of Barley, Steeped Barley, and Malt Polyphenoloxidase
A comparative chromatography of polyphenoloxidase isolated from barley, steeped barley, and green malt was made. It consisted ofextraction, precipitation, ion-exchange chromatography, gel filtration, and electrofocusing. Polyphenoloxidase was resolved into a high-molecularweight enzyme and a low-molecular-weight one. The proportion of the two enzymes underwent variations during malting. An incr...
متن کاملAntioxidant and cytoprotective properties of partridgeberry polyphenols.
Partridgeberry (Vaccinium vitis-idaea) is a polyphenol-rich berry of the Ericaceous family, grown in Newfoundland and Labrador province of Canada. The aims of this study were to identify extraction solvents for the maximum recovery of polyphenols, to establish fractionation technique for isolation of major sub-classes of polyphenols, and to evaluate antioxidant and cytoprotective properties of ...
متن کاملAntioxidant Properties of Polyphenols and Their Potential Use in Improvement of Male Fertility: A Review
There has been a growing interest in the use of plant bioactive substances, such as polyphenols, as antioxidants in assisted reproduction technologies. Previous studies have focused on the use of vitamins C and E as potent antioxidants for semen cryopreservation in mammals [1,2]. However, some polyphenols such as quercetin, a secondary metabolite in plants, have been found to exhibit higher ant...
