Abstract

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%.

수집종 아주까리 40종의 유전자원을 농촌진흥청 농업생명공학연구원 유전자원과로부터 분양받아 바이오디젤 가능 작물로서 조지방 및 지방산 분석결과는 다음과 같다. 수집종 아주까리 종자의 gas chromatogram은 6개의 피크를 보였고, ricinoleic acid의 retention time은 12.7분대이었다. 아주까리 수집종의 평균 기름 함량은 $44.6{\sim}49.4%$이었으며, 최저 41.4%와 최고 52.2%로 10.8%의 차이가 있었다. 지방산 조성은 불포화지방산이 97.6%로 대부분이었으며, 포화지방산은 2.4% 정도로 낮은 함량을 보였다. 지방산 조성은 87.3%가 ricinoleic acid이었으며, oleic acid와 linoleic acid가 각각 4.6%, 5.2%이었다. palmitic acid와 stearic acid의 함량은 1% 내외로 차이가 미미하였고, linolenic acid의 함량은 0.6% 정도로 가장 낮았다.
