查询词典 flavonoid

The highest total flavonoid rate was 1.127%. An all-round evaluation for the antioxidant activity of the flavonoids extract from zizania-bract was carried out with that of ascorbic acid as the control. The evaluation indexes included the cleanup rate of the polyphenolic extract towards superoxidized anionic radicals, hydroxyl radicals, DPPH free radicals, the deoxidizing ability, and the antioxidant activity towards the peroxidize of lipids and edible oils.
