| Abstract: |
| In order to explore the potential of Kadsura coccinea seed as a new plant oil resource, the amino acids and lipids were detected and analyzed by widely targeted metabolomics. The results showed that under the classification based on the identified metabolite structure configuration, the Kadsura coccinea seed contained 121 lipid and 89 amino acid and derivative compounds, respectively, and the number and the relative content (30.7%) of the former was the highest among the 11 types of components, the number of the latter was the second, and the relative content (17.8%) was the third. 20 kinds of basic amino acids and 8 kinds of essential amino acids were identified. The contents of 7 kinds of medicinal amino acids (such as L-proline, L-aspartic acid and L-serine) and 5 kinds of essential amino acids (such as L-leucine, L-threonine, L-isoleucine, L-phenylalanine and L-lysine) were higher. Kadsura coccinea seed was rich in fatty acids such as linoleic acid, γ-linolenic acid and α-linolenic acid, as well as phospholipids dominated by lysophosphatidylcholines 18∶ 2 and 18∶ 2 (2n isomer). In conclusion，Kadsura coccinea seed is rich in amino acids and lipids, and a variety of highly enriched components have outstanding nutritional functions, activities and medicinal effects, and have high value in the development of high-quality vegetable oils and other fields. |
