Studies on the Composition of Sapindus Mukurossi Seeds

무환자(無患子)나무 종자(種字)의 성분(成分)에 관(關)한 연구(硏究)

The composition of fatty acids and sterols from Sapindus Mukurossi oil were analyzed by gas liquid chromatography and amino acids from Sapindus Mukurossi seed oil cake were determined by amino acid autoanalyzer. The results obtained were summarized as follows; 1. Oil content (45.7%) was higher in Sapindus Mukurossi seed than in other plant seeds such as soybean, sesame and peanut. 2. From the analysis of fatty acids, it was found that oleic acid(61.6%) and gadoleic acid(20.4%) were major fatty acid and that high monoenoic acid content(82%) could be a characteristic of sample seed oil. 3. Glutamic acid contained the most amounts among all amino acids determined, and isoleucine, leucine, lysine, phenylalanine, threonine and valine were relative high amounts compared with content of other amino acids. 4. The sterol compositions of 4-desmethyl sterol, 4-monomethyl sterol and 4,4-dimethyl sterol fraction were found to be similar to those of higher plant oil, but 4-monomethyl sterol fraction was characterized by containing the unknown sterol (31.5%) with RRT 1.27.

1. 무환자(無患子)나무종자중(種字中)의 유지함량(油脂含量)은 45.7%로서 콩, 참깨, 땅콩에 비해서 많은 편에 속한다. 2. 지방산(脂肪酸)은 Oleic acid(61.6%)와 Gadoleic acid(20.4%)로서 주요성분(主要成分)을 이루고 있고 monoene산(酸)이 전체지방산(全體脂肪酸)의 82%를 차지하고 있는것이 특징적(特徵的)이다. 3. Amino산조성(酸組成)은 Glutamic acid의 함량(含量)이 6.673%로서 가장높고 대체적으로 필수(必須) amino산(酸)인 Isoleucine(1.255%), Leucine(2.145%), Lysine(2.191%), Phenylalanine(1.536%), Threonine(1.171%), Valine(1.772%)등이 함량(含量)이 높았다. 4. Sterol조성(組成)은 4-desmethyl sterol, 4-monomethyl sterol fraction에서 다 같이 일반고등식물중(一般高等植物中) 성분(成分)과 대차(大差)가 없었으며 단지 4-monomethyl sterol fraction에 있는 RRT 1.27(31.5%)의 미동정물질(未同定物質)이 있다는 것이 특이(特異)하였다.
