[Oil contents and fatty acid composition in Jatropha curcas seeds collected from different regions].
OBJECTIVE
To compare the oil contents and fatty acid composition among the samples of Jatropha curcas L. seeds collected from China (Guangdong, Hainan, and Guizhou Provinces) and India.


METHODS
Soxhlet extraction method and gas chromatography-mass spectrometry (GC-MS) were employed to determine the oil contents of Jatropha seeds and the fatty acid composition of Jatropha oil.


RESULTS
The seed oil contents (dry basis) were 32.43% (Guangdong), 31.41% (Hainan), 37.56% (Guizhou) and 41.04% (India), respectively. Twelve different fatty acids were detected by GC-MS, and the content of total unsaturated fatty acids accounted for 80.93%, 79.53%, 77.24% and 78.22% of the total fatty acids in the samples collected from Guangdong, Hainan, Guizhou and India, respectively.


CONCLUSIONS
There are differences in the oil contents and fatty acid composition among the J. curcas seeds collected from different regions, and attention should be given to these differences in the introduction and breeding of J. curcas.
