Determination of Crude Fat of Seeds of Jatropha curcas L. in Different Areas

Crude fat of Jatropha curcas L.which was from Yuanmou,Lianghe,Yongsheng and Yuanyang of Yunnan,Lao and Rwanda was determined by soxhlet extraction in the paper.The experimental results showed that crude fat content in the hulls,kernels and seeds of Yuanmou Jatropha curcas L.was 2.30%,43.46%,34.50%,respectively.Crude fat content in the hulls,kernels and seeds of Lianghe Jatropha curcas L.was 2.97%,58.32%,32.57%,respectively.Crude fat content in the hulls,kernels and seeds of Yongsheng Jatropha curcas L.was 0.98%,55.48%,33.45%,respectively.Crude fat content in the hulls,kernels and seeds of Yuanyang Jatropha curcas L.was 1.16%,47.42%,31.47%,respectively.Crude fat content in the hulls,kernels and seeds of Lao Jatropha curcas L.was 1.11%,64.69%,37.75%,respectively.Crude fat content in the hulls,kernels and seeds of Rwanda Jatropha curcas L.was 1.99%,51.02%,30.56%,respectively.
