Abstract:
In this study, Xanthoceras sorbifolia seed oil was extracted by a two-step method . At the first step, Xanthoceras sorbifolia was roughly extracted at low temperature by oil press, and the bottom oil in the seed cake was 15.23%. At the second step, the seed cake was soaked in diethyl ether under the following conditions: solvent-material ratio of 5:1, extracting time of 6h, and extracting times of 4, under which the bottom oil was 1.34%. The contents of fatty acids in the final extracts were analysed by gas chromatograph. Results showed that the extracted oil contained oleic acid and linoleic acid and the total content of unsaturated fatty acid reached 92.12%.
