종려과실%총황동%항양화작용
palm fruits%total flavonoids%antioxygenation
为给棕榈的综合利用及开发提供依据，采用分光光度计法和DPP H法测定棕榈果实的总黄酮含量及其抗氧化活性。结果表明：当棕榈果实中总黄酮的含量为1728．15μg/g，棕榈果实总黄酮提取液浓度为772μg/mL时，对DPPH自由基的清除率为69．98％；而总黄酮提取液浓度为0．5058μg/mL时，对油脂的过氧化值为0．052。
為給棕櫚的綜閤利用及開髮提供依據，採用分光光度計法和DPP H法測定棕櫚果實的總黃酮含量及其抗氧化活性。結果錶明：噹棕櫚果實中總黃酮的含量為1728．15μg/g，棕櫚果實總黃酮提取液濃度為772μg/mL時，對DPPH自由基的清除率為69．98％；而總黃酮提取液濃度為0．5058μg/mL時，對油脂的過氧化值為0．052。
위급종려적종합이용급개발제공의거，채용분광광도계법화DPP H법측정종려과실적총황동함량급기항양화활성。결과표명：당종려과실중총황동적함량위1728．15μg/g，종려과실총황동제취액농도위772μg/mL시，대DPPH자유기적청제솔위69．98％；이총황동제취액농도위0．5058μg/mL시，대유지적과양화치위0．052。
To provide the basis for comprehensive utilization and development of palm,the content and antioxidant activity of total flavonoids from palm fruit were determined by spectrophotometry and DPPH method.Results:The total flavonoids content of palm fruit was 1 728.15 μg/g.The free radical scavenging rate was 69.98% when the total flavonoids extract concentration was 772μg/mL,The oil antioxidant POV achieved 0.052 when the total flavonoids extract concentration was 0.505 8μg/mL.
