| 摘 要： | 为了解谷子的抗氧化功效,以5个谷子品种为研究对象,测定了谷子醇提物中抗氧化活性物质的含量,比较了不同谷子品种醇提物的抗氧化能力,并分析了抗氧化能力与活性成分含量的相关性。结果显示,5个谷子品种总酚、黄酮、α-生育酚含量分别为369.9~793.1、162.1~459.3、7.1~17.1 mg/kg;谷子醇提物的DPPH自由基清除率、OH自由基清除率、还原力的IC50值分别为0.09~0.24、0.41~0.74、0.98~2.35 mg/mL。其中,张杂谷9号的黄酮含量最高,总酚、α-生育酚含量最低,DPPH自由基清除能力最强;8311总酚和α-生育酚含量最高,黄酮含量最低,OH自由基清除能力最强;张杂谷3号提取物的还原力高于其他4个品种。相关性分析结果显示,谷子提取物对DPPH自由基的清除能力与总酚、α-生育酚含量呈显著正相关,与黄酮含量呈显著负相关;对OH自由基的清除能力与总酚、α-生育酚含量呈显著负相关,与黄酮含量呈显著正相关;还原力与α-生育酚含量呈显著负相关。

| Abstract: | In order to study the antioxidant activity of millet,5 millet cultivars were used to determine the content of antioxidative substance,the antioxidant capacity of alcohol extract from different millet cultivars were compared, and the relationship between the antioxidant capacity and the content of antioxidative substance was analyzed. The results showed that the content of the total phenol, flavonoid and alpha tocopherol ranged from 369. 9 to 793. 1 mg/kg, 162. 1 to 459. 3 mg/kg and 7. 1 to 17. 1 mg/kg, respectively. The IC50 of DPPH free radical scavenging, OH free radical scavenging and the power of reducing ranged from 0. 09 to 0. 24 mg/mL,0. 41 to 0. 74 mg/mL and 0. 98 to 2. 35 mg/mL respectively. Zhangzagu No. 9 had the lowest contents of polyphenols,alpha tocopherol,the highest flavonoid content, and the DPPH free radical scavenging capacity was the highest in all test cultivars. 8311 had the highest total polyphenols and alpha tocopherol contents,the lowest flavonoid content,the strongest OH free radical scavenging capacity. Zhangzagu No. 3 had the highest power of reducing. The correlation analysis showed that the DPPH free radical scavenging capacity was positively correlated with the contents of total polyphenol and alpha tocopherol, negatively correlation with flavonoid content. The OH free radical scavenging capacity was negatively correlated with the contents of total polyphenol and alpha tocopherol, postively correlated with flavonoid content. The reducing power was negatively correlated with alpha tocopherol content. |
