摘 要:以薜荔果为研究对象,采用超声波辅助法提取薜荔果总黄酮,通过单因素实验和正交试验设计确定最佳提取工艺条件,并从对·OH、DPPH·及·NO的清除效果研究薜荔果总黄酮的抗氧化活性。结果表明,薜荔果总黄酮的最佳提取工艺条件:60%乙醇、1∶25(g/mL)料液比、提取温度60℃及提取时间120 min,在此条件下薜荔果总黄酮提取率为8.87%。薜荔果总黄酮对·OH、DPPH·及·NO的清除效果与浓度间存在量效关系,其中对DPPH·的清除效果较好,IC_(50)值为0.0033 mg/mL,表明薜荔果中的总黄酮具有一定的抗氧化活性。The fruits of Ficus pumila were taken as the research object,the total flavonoids were extracted from Ficus pumila fruit by ultrasonic-assisted extraction.The optimum extraction conditions were investigated based on orthogonal design.The antioxidant activity of Ficus pumila fruit total flavonoids was evaluated from scavenging effects on·OH,DPPH·and·NO.Results showed that the optimum extraction conditions were 60%ethanol,1∶25(g/mL)ratio of material to liquid,extraction temperature of 60℃and 120 min of extraction time,respectively.Under this condition,the extraction rate of total flavonoids from Ficus pumila fruit was 8.87%.The scavenging effects of Ficus pumila fruit total flavonoids on·OH,DPPH·and·NO showed dose-effect relationship with the total flavonoids concentration.And the scavenging effect of DPPH·was better,the corresponding IC_(50)value was 0.0033 mg/mL.The results showed that the total flavonoids in Ficus pumila fruit had certain antioxidant activity.
