The property and composition of fatty acid of Camptotheca acuminate seed oil were studied, which was extracted by supercritical carbon dioxide extraction method. The result suggested that the C. acuminate seed oil was rich in unsaturated fatty acid. The relative content of oleic acid, linoleic acid, α-linolenic acid were 12.517 3%,28.263 9% and 45.684 4% respectively. The content of camptothecin is 0.125 9‰ in C. acuminate seed oil. The other property of C. acuminate seed oil is good.
