西北地区6种卫矛科植物种子氨基酸分析

Amino Acid Analysis of Six Celatraceae Plant Seeds Produced in the Northwest of China

目的:对西北地区生长的扶芳藤(Euonymus fortunei)、陕西卫矛(E.schensianus)、苦皮藤(Celastrus angulatus)、疣枝卫矛(E.verrucosoides)、白杜(E.maackii)和冬青卫矛(E.japoni-cus)等6种卫矛科植物种子中的水解氨基酸进行了分析。方法:用石油醚将种子脱脂得到种粕,然后用盐酸水解,再经脱盐后用氨基酸分析仪对水解氨基酸进行测定。结果:18种氨基酸从这6种植物种子中检出,人体所需的8种必需氨基酸含量都在38 mg/g以上,占所含氨基酸总量的43%,并且对人体新陈代谢有重要作用的精氨酸含量特别高,苦皮藤、疣枝卫矛和白杜种子中高达22mg/g。结论:初步研究显示该类植物种子营养丰富,且有一定的药用价值。

To analyze amino acid in seeds of the Celastraceae plants Euonymus fortunei,E, schensianus, Celastrus angulatus,E, verrucosoides,E, maackii and E. japonicus produced in the Northwest of china. Methods： The degreased seeds were hydrolyzed by hydrochloric acid and analyzed by amino acid analysis system. Results： 18 kinds of amino acid were identified from the seeds six plants. The contents of essen tial amino acids were more than 38 mg/g accounting for 43% of the total. The content of arginine was very high, which plays an important role in the metabolism of human body. It was up to 22 mg/g in the seeds of C. angulatus,E, verrucosoides and E. bungeanus. Conclusion： The seeds of six plant are rich in nutri tients ,and show.some medicinal functions.
