Abstract

With the seed of Nadina domestica T.as raw material,the seed oil was obtained by ultrasonic-assisted extraction.The physicochemical properties of Nadina domestica T.seed oil were determined and its fatty acid composition was analyzed by GC-MS.The results showed that the acid value,saponification value,peroxide value,iodine value,relative density(20 ℃) and refractive index(20 ℃) of Nadina domestica T.seed oil were 1.44 mgKOH/g,187.04 mgKOH/g,1.42 mmol/kg,114.51 gI/100 g,0.912 7 and 1.472 6,respectively.Thirteen kinds of fatty acids were identified form Nadina domestica T.seed oil and the main fatty acids were linoleic acid(60.96%),palmitic acid(15.55%),oleic acid(15.16%) and stearic acid(4.67%).The content of unsaturated fatty acids was up to 77.99%.
