摘 要：
The physico-chemical properties and thermal oxidation stability of Akebia trifoliata var.australis seed oil extracted by hexane was evaluated in this paper.The results showed that the contents of crude fat and protein in the seeds of Akebia trifoliata var.australis were 39.33% and 17.97%,respectively.The acid value,peroxide value,p-anisidine value,iodine value and saponification value of the extracted oil were 1.28 mgKOH/g,0.57 mmol/kg,4.15,74.12 gI2/100 g and 198.6 mg KOH/g,respectively.Gas chromatographic analysis indicated that the seed oil was rich in palmitinic acid,oleinic acid and linoleic acid,which altogether accounted for 93.73% of total fatty acids.In addition,the extracted oil revealed an absorption maximum at 212 nm and excellent thermal oxidation stability below 220 ℃.
