Antioxidative flavan-3-ol glycosides from stems of Rhizophora stylosa.
Two flavan-3-ol glycosides together with seven flavan-3-ols were isolated from stems of the mangrove plant, Rhizophora stylosa. Their structures were established as glabraoside A (7) and glabraoside B (8) by spectroscopic and chemical methods. The antioxidative activity of these isolated compounds evaluated by the diphenylpicrylhydrazyl (DPPH) radical scavenging reaction was higher than that of...
متن کاملChanges of flavan-3-ols with different degrees of polymerization in seeds of 'Shiraz', 'Cabernet Sauvignon' and 'Marselan' grapes after veraison.
Flavan-3-ols consist of flavan-3-ol monomers and polymers with different degrees of polymerization (DP). In this study, flavan-3-ol extracts from grape seeds were well separated into three fractions including monomers, oligomers (2 < DP < 10) and polymers (DP > 10), by means of normal-phase HPLC-MS. The different patterns of these three fractions were analyzed in three Vitis vinifera cultivars ...

متن کاملAntioxidant effects of grape vine cane extracts from different Chinese grape varieties on edible oils.
This study involved the determination of the peroxide value (POV) as a measure of the resistance of the oxidation of edible oil with grape vine cane additives to assess their antioxidation potential. The study demonstrated that grape extracts of canes could effectively inhibit the lipid oxidation of edible oils and that this ability varied significantly due to the different extraction solvents ...
متن کاملFlavan-3-ol Compounds from Wine Wastes with in Vitro and in Vivo Antioxidant Activity
It has been suggested that the dietary intake of antioxidant supplements could be a useful strategy to reduce the incidence of diseases associated with oxidative stress. The aim of present work is to study the possibility to obtain compounds with antioxidant activity from wine wastes using water as solvent. Results have shown that it is possible to obtain flavan-3-ol compounds from wine wastes ...
