芸苔属植物种子蛋白质及脂肪酸成分研究
A STUDY ON THE SEED PROTEINS AND FATTY ACID COMPOSITIONS OF SEED OILS FROM BRASSICA PLANTS
-
摘要: 本文对芸苔属(Brassica)19个植物种和变种的种子作了蛋白质、油脂及脂肪酸成分的系统分析。该属植物种子含蛋白质21.2—28.8%,油脂29.3—43.2%,均含有相同的至少13种脂肪酸成分,芥酸是其主要的也是特征脂肪酸,占总脂肪酸的24.2—52.0%。芥酸含量大于50%的种有紫菜苔、塌棵菜、白菜和花椰菜;笋子芥芥酸含量最低,为24.2—30.5%。Abstract: The seed proteins from 20 species(or varieties) of genus Brassica plants were determind and their fatty acid compositions in the seed oils were analysed by gas liquid chromatography. The seeds of genus Brassica plants studied contain 21.2—28.8% protein and 29.3—43.2% oil on dry base. All the seed oils of the plants contain same 14 fatty acid components, among them characteristic fatty acid is the erucic acid which makes up 24.2—52.0% of the seed oils. The other major fatty acids are oleic acid (8.4—20.6%), linoleic acid(8.8—20.4%), linolenic acid (5.2—12.5%) and gadoleic acid(4.4—11.7%). Contents of the proteins and fatty acid components in the different species of Brassica are different, but those in B. norinosa are similar to those in B. chinensis, This results support the view of Tsen et Lee who regard B. norinosa as a variety, B. chinensis var. rosularis, not a real species of Brassica.
