The study aimed to analyze the oil content in seed kernel and the components of fatty acid in the seed oil of Koelreuteria bipinnata Var.integrifolia T.Chen.[Method] The seed oil of K.bipinnata was extracted with soxhlet extraction and the oil content in seeds was calculated.The component of fatty acid in seed oil was detected with gas chromatograph-mass spectrometer after the fatty acid being methyl esterified.[Result] The oil content in seed kernel of K.bipinnata reached 54.04%.There were 5 saturated fatty acids and 3 unsaturated fatty acids in seed oil,among which,the content of unsaturated fatty acid reached 75.26%,and the unsaturated fatty acid mainly contained oleic acid(31.07%),eicosenoic acid(35.07%) and erucic acid(9.12%). The nutrition value of seed oil of K.bipinnata was higher,but in which there were no polyunsaturated fatty acid with more higher nutrition value and there were erucic acid and arachidic acid that indigestible in the oil.[Conclusion] The seed oil of K.bipinnata had higher nutrition value,but whether it could be used as edible oil needs to make the toxicological study.
