| 中文摘要: |
| 采用GC-MS、原子吸收和常规分析法研究八月瓜果籽油的功能成分，通过测定过氧化值和自由基清除率考察八月瓜果籽油的抗氧化活性。结果表明，八月瓜果籽油的酸值（KOH）、皂化值(KOH)和碘值(I)分别为1.23、260 mg/g和83.02 g/100 g。八月瓜果籽油脂肪酸组成主要为棕榈酸（30.08%）和油酸（48.93%），其油中钾、钠、钙、镁、锌含量分别为2.57、5.12、3.15、0.23、0.21 mg/g。在芝麻油中添加八月瓜果籽油，分别用235 nm紫外光照射450 min和在80℃加热60 min，芝麻油过氧化值比添加BHT的分别降低11.46%和16.81%；比较八月瓜果籽油与芝麻油、VE、异VC-Na和BHT的自由基清除能力，结果发现八月瓜果籽油的还原能力、超氧阴离子自由基和H2O2清除能力最强。 |

| The functional components of Akebia trifoliate seed oil were analyzed by GC-MS, atomic absorption spectrometry and conventional analysis method, and its antioxidant activity was investigated by determining the peroxide value and free radical scavenging rate. The results showed that the acid value, saponification value and iodine value of Akebia trifoliate seed oil were 1.23, 260 mgKOH/g and 83.02 gI/100 g, respectively; the fatty acid composition of Akebia trifoliate seed oil was mainly palmitic acid（30.08%） and oleic acid（48.93%）, and the contents of potassium, sodium, calcium, magnesium and zinc in Akebia trifoliate seed oil were 2.57, 5.12, 3.15, 0.23, 0.21 mg/g, respectively.Akebia trifoliate seed oil was added to sesame oil to be irradiated by UV at 235 nm for 450 min and heated at 80℃ for 60 min respectively,and the peroxide values of sesame oil decreased by 11.46% and 16.81% respectively compared with those of sesame oil added with BHT; the free radical scavenging rate of Akebia trifoliate seed oil was compared with that of sesame oil, VE, D-sodium isoascorbiate and BHT, and the results indicated that the reducing power and scavenging activities on superoxide anion free radical and H2O2 of Akebia trifoliate seed oil were the strongest. |
