Effect of plant growth temperature on antioxidant capacity in strawberry.

摘要: The influence of four day/night growing temperature combinations (18/12, 25/12, 25/22, and 30/22 °C) on phenolic acid, flavonol, anthocyanin content their antioxidant activities against peroxyl radicals (ROO•), superoxide (O2•-), hydrogen peroxide (H2O2), hydroxyl (OH•), singlet oxygen (1O2) in fruit juice Earliglow Kent strawberry (Fragaria × ananassa Duch.) cultivars was studied. Pelargonidin-based anthocyanins such as pelargonidin 3-glucoside (291.3−945.1 μg/g fresh wt.), 3-rutinoside (24.7−50.9 3-glucoside-succinate (62.2−244.0 wt.) were the predominant juice. cyanidin-based anthocyanins, cyanidin 3-glucoside-succinate, much lower than that pelargonidin-based anthocyanins. Strawberry growth high conditions significantly enhanced p-coumaroylglucose, dihydroflavonol, quercetin 3-glucoside, 3-...
