The fatty acid composition in the seed and flower of Ligustrun lucidum and olive oil was studied by Gas Chromatography. Results showed that the main components of seed oil were Palmitic (C16:0) 5,893% ,Palmitolic acid (C16:1)0,398%, Steaeic (C18:0)2,911% ,Oleic (C18:1)74,984%,Linoleic (C18:2) 12,959%,and Linolenic (C18:3) 0,997%. The proportion of unsaturated fatty acid was above 89,338%, so the seed oil of L. lucidum ait belonged to unsaturated oil which possessed promising application. The components of flower oil were Palmitic (C16:0) 65,674% ,Palmitolic acid (C16:1)6,516%, Steaeic (C18:0)2,641% ,Oleic (C18:1)14,707%,Linoleic (C18:2) 3,113%,and Linolenic (C18:3) 2,70%. The proportion of unsaturated fatty acid and saturated fatty acid was above 26,406%, 68,315%,respectively so the flower oil of ligustrun lucidum belonged to saturated oil . the main components of olive oil were Palmitic (C16:0) 13,364% ,Palmitolic acid (C16:1)0,834%, Steaeic (C18:0)3,860% ,Oleic (C18:1) 68,668%,Linoleic (C18:2) 12,586%,and Linolenic (C18:3) 0,687%. The proportion of unsaturated fatty acid was above 82,775%, so the olive oil of ligustrun lucidum ait belonged to. These values of seed oil are very similar to that found in the olive oil.

Abstract. Title of the paper: Analysis of the fatty acid composition of the raw fat from the feed of pigs which are examined to her performance (short communication) The raw fat of 14 examining feeds from 13 German performance testing centres for pigs was extracted 2001 and analysed for the fatty acid composition by means of gas chromatography. Besides a great variation of the raw fat content (s % = 42) was to state that with 14.4 g/kg feed on average the content of polyunsaturated fatty acids (PUFA) was high. Examinations of the raw fat of wheat, rye and barley showed that the high proportions in linoleic and linolenic acid are brought in the fattening rations primarily by the cereal components. A limitation of the PUFA proportions below 15 g/kg feed therefore doesn't seem to be practicable in the examining feed of performance testing centres for pigs. The additional variation in the fatty acid composition of examining feeds caused by added fats or oils should however be limited according to a better standardization.
