[Determination of oil contents and fatty acids in seeds of Torreya Arn. in China].
OBJECTIVE
To analyze the oil contents and fatty acid composition in the seeds of Torrreya in China.


METHODS
The contents and composition were determined by gravimetric analysis and GC respectively.


RESULTS
The oil contents in the seeds were 42.67%-54.39%. Among the fatty acids, linoleic acid and oleic acid were dominant. The unsaturated fatty acids accounted for 76.1%-82.0% of the whole fatty acids, and the major saturated fatty acids were behenic acid and palmitic acid.


CONCLUSIONS
The oil in the seeds of Torreya is of high-quality, and the higher contents of bdhenic acid are characteristic for the oil. The development and utilization values of the seed oil in Torreya are evaluated.
