    Author: Wang ZY, Lin JM, Xu ZF.
    Journal: Nan Fang Yi Ke Da Xue Xue Bao; 2008 Jun; 28(6):1045-6. PubMed ID: 18583260.
    Abstract:
    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. CONCLUSION: 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.
