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.

采用抗坏血酸作为对照，全面测定了茭白苞叶总黄酮对超氧阴离子自由基、羟基自由基、DPPH自由基的清除率，以及还原能力、抗脂质过氧化活性和对食用油脂的抗氧化性的影响，结果表明，白苞叶中的总黄酮是一种有开发价值的天然抗氧化剂。
