Abstract

The fatty acids composition of Lactuca sativa L.seed oil was analyzed by GC/MS.The physicochemical properties of the oil were also determined,such as acid value,saponification value,iodine value,refractive index and relative density according to national standards.The results showed that 10 kinds of fatty acids were identified such as linoleic acid(53.18%),oleic acid(17.22%),palmitic acid(11.58%),and the contents of unsaturated fatty acids in the Lactuca sativa L.seeds oil were up to 75%.
