| Abstract: |
| The compositions of fatty acid and amino acid of Koelreuteria bipinnata seed kernel were analyzed according to the national standard methods. The results showed that the content of crude fat in K. bipinnata seed kernel was 11.4%. Fifteen kinds of fatty acids were identified in K. bipinnata seed kernel oil, mainly including eicosenoic acid (45.4%), oleic acid (23.7%), linoleic acid (9.2%), palmitic acid (6.1%) and erucic acid (5.6%). Unsaturated fatty acids were up to 87.20%, and monounsaturated fatty acids accounted for 74.95%. The contents of crude protein and amino acid of K. bipinnata seed kernel were 26.2% and 19.29% respectively. At least sixteen kinds of amino acids were identified in the seed kernel protein of K. bipinnata, in which the content of essential amino acids accounted for 33.59% and medicinal amino acids accounted for 70% of the total amino acids. The research showed that K. bipinnata seed kernel had broad prospects for utilization, because it could not only be used as raw material of biodiesel, medical supplies and cosmetic, but also be used as good resources of nutritional protein and edible oil. |
