[Objective] The aim was to promote the process and utilization of Canarium album deeply and provide the basis for better development and utilization of Canarium album resources.[Method] The flesh oil and kernel oil in Canarium album fruit were extracted by soxhlet extraction method and its fatty acid composition was analyzed comparatively by gas chromatography-mass spectroscopy(GC/MS).[Result] The fat in Canarium album fruit existed mainly in nucleolus and the fat content in flesh was less.The main fatty acid species in Canarium album kernel oil and flesh oil was basically same,but the relative content of every component had a little difference.13 fatty acids were detected in Canarium album kernel oil.Among them,the content of unsaturated fatty acid was 73.3% with the linoleic acid as the main.10 fatty acids were detected in Canarium album flesh oil. Among them,the content of unsaturated fatty acid was 70.4% with the oleic acid as the main.The relative content of oleic acid in Canarium album flesh oil and kernel oil was 55.2% and 30.5%,resp.and that of linoleic acid was 4.7% and 41.8%,resp.[Conclusion] The nutrition and health value of Canarium album was higher and it had better development and utilization prospect.
