Abstract

Unsaturated fatty acid was obtained from Antinidia chinensis Planch seeds.The contents of each fatty acid component in product are as follows:palmitic acid 4.82%,stearic acid 3.72%,oleic acid 13.11%,lindeic acid (10.36%),linolenic acid 64.99%,arachidonic acid 2.03%,respectively.The optimum conditions of extraction by (orthogonal) tests are:temperature 60 ℃,time 30 min,ratio of liquor to material:petroleum ether(mL)∶seeds(g) (4.0∶1.0),extract 3 times.Under such conditions,the yield of the extraction is 29.70%.
