| 摘 要： | 利用不同的方法检测葡萄籽超微粉经体外消化后的抗氧化能力。通过对总酚和原花青素含量的测定、及抗脂质过氧化能力、清除羟自由基能力、清除DPPH(1,1-Diphenyl-2-picrylhydrazyl)、ABTS(2,2'-azino-bis(3-ethylbenzthiazoline-6-sulphonic acid))自由基能力、铜离子还原能力的测定,得出:葡萄籽超微粉具有很高的自由基清除能力、还原能力和抗脂质过氧化的能力。在利用透析袋模拟抗氧化活性物质的吸收实验中,大量的抗氧化活性物质能够以被动吸收的方式进入透析袋内,透析液具有很强的抗氧化能力。

| Abstract: | We used several different methods to determin the antioxidant capacity of ultra-fine powder of grape seeds after in vitro digestion.The antioxidant potential of the extract was assessed by performing different in vitro assays,such as the total content of phenonic and the procyanidins,CUPRAC,DPPH.,ABTS and OH radical scavenging capacities and peroxidation inhibiting activity.The results showed that the sample exhibited strong antioxidant activity.Dialyzing bag was used to simulate the gastrointestinal assimilation;much of strong active antioxidants permeated into the dialyzing bag by passive absorption. |
