摘要:
拟测定黄秋葵水提物主要功能成分,并系统研究其水提物的体外抗氧化作用,为黄秋葵今后的开发利用提供相应的理论基础。试验得到水提烘干与冻干2种样品,对其中的功能成分进行测定,通过不同自由基[2,2′-联氮-二(3-乙基-苯并噻唑-6-磺酸)二铵盐自由基(ABTS+·)、1,1-二苯基-2-三硝基苯肼自由基(DPPH·)、羟自由基(·OH)、超氧阴离子自由基( O-2 · )]清除能力的测定,以及铁离子还原/抗氧化能力(ferric ion reducing antioxidant power,简称FRAP)和氧化自由基吸收能力(oxygen radical absorbance capacity,简称ORAC)的测定,系统地对水提物的体外抗氧化活性进行研究。结果表明,黄秋葵水提物抗氧化能力和浓度有一定的量效关系,对ABTS+·、DPPH·、·OH、 O-2 · 的EC50分别为0.1、0.2、8.3、0.9 mg/mL,FRAP为(365.5±5.30)μmol/g(以Trolox计),ORAC为180.2 μmol/g(以Trolox计)。由结果可知,黄秋葵具有良好的抗氧化性,有极好的开发前景。
