In the current investigation, total phenols and flavonoids contents of (Mill.) Urb. bulbs, leaves, and flowers were quantified by Folin-Ciocalteu's and borohydride/chloroquinone methods, respectively. Antioxidant activity of the plant extracts was evaluated by means of peroxide scavenging capacity assay and by cell antioxidation method. Antioxidant activity of bulbs, leaves, and flowers was correlated with total phenols and flavonoids. The total phenols and flavonoids of the bulbs of were higher than leaves and flower and its antioxidant activity was also stronger than leaves and flowers of . The higher content of flavonoids or total phenols, the stronger the antioxidant capacity in vitro. The antioxidant activity of extract showed it's certain nutritional value and therefore had the potential as a source of natural antioxidants.
在当前的研究中,分别采用福林-西奥尔特法和硼氢化物/氯醌法对(Mill.)Urb.的鳞茎、叶片和花朵中的总酚和黄酮含量进行了定量分析。通过过氧化物清除能力测定法和细胞抗氧化法对植物提取物的抗氧化活性进行了评估。该植物鳞茎、叶片和花朵的抗氧化活性与总酚和黄酮相关。其鳞茎中的总酚和黄酮含量高于叶片和花朵,其抗氧化活性也强于叶片和花朵。黄酮类化合物或总酚含量越高,体外抗氧化能力越强。该提取物的抗氧化活性表明其具有一定的营养价值,因此有潜力作为天然抗氧化剂的来源。
