Forty Ricinus communis collections were obtained from RDA National Agrobiodiversity Center for knowing the possibility of the use as a bio-diesel possibility crop. These are analysis results about crude fat and fatty acid. Gas chromatogram of seed collections analysis showed 6 peaks and retention time of ricinoleic acid was about 17.1 minute. Average oil content of collections were ranged from 44.6 to 49.4% and the difference was between maximum 52.5% and minimum 41.4%. Fatty acid composition was almost unsaturated fatty acid of 97.6% and saturated fatty acid showed low content of 2.4%. Ricinoleic acid was 87.3% and the content of oleic acid and linoleic acid in fatty acid was 4.6%, and 5.2%, respectively. The content of palmitic acid and stearic acid was about 1% and the difference was insignificant. The content of linolenic acid was extremely low as 0.6%.
