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 determinec by amino acid autoanalyzer.
The results obtained were summarized as follows;
1. Oil conient (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.
