| 中文摘要: |
| 采用气相色谱法对不同地区多个品种油菜籽的脂肪酸组成及含量进行分析。结果表明：不同地区各油菜籽品种所含脂肪酸组成基本相同，均含有17种脂肪酸，脂肪酸种类比较丰富；油菜籽中含量较多的脂肪酸有油酸、芥酸、亚油酸、亚麻酸和花生一烯酸，各品种油菜籽间油酸、芥酸和花生一烯酸含量差异较大，亚油酸和亚麻酸含量差异较小；杂交、丰油10号和杂双5号油菜籽可作为丰富的油酸、亚油酸来源，搏优6号和皖油13油菜籽可作为丰富的花生一烯酸来源，南阳红、秦优9号、花菜子和四月红油菜籽可作为丰富的芥酸来源，杂双5号油菜籽可作为低芥酸菜籽油的原料来源；种植土壤对杂交油菜籽脂肪酸含量影响较大，而丰油10号油菜籽脂肪酸含量不受种植土壤的影响，无论是杂交油菜籽还是丰油10号油菜籽，在相同种植土壤条件下，即使来自不同地区，同品种油菜籽脂肪酸含量均无明显差异。 |
| 英文摘要: |
| The fatty acid composition and content of rapeseed in different areas was detected by GC. The results showed that the fatty acid composition of the rapeseed varieties in different areas was basically the same, which contained 17 fatty acids, and the types of fatty acids were relatively rich. The rapeseed was rich in oleic acid, erucic acid, linoleic acid, linolenic acid and eicosenoicacid. The contents of oleic acid, erucic acid and eicosenoicacid were quite different and the contents of linoleic acid and linolenic acid were less different. The Zajiao, Fengyou No.10 and Zashuang No.5 rapeseed could be used as rich sources of oleic acid and linoleic acid. Boyou No.6 and Wanyou No.13 rapeseed could be used as rich sources of eicosenoicacid. Nanyanghong, Qinyou No.9, Huacaizi and Siyuehong rapeseed could be used as rich sources of erucic acid. Zashuang No.5 rapeseed could be used as a source of raw material for canola oil. The planting environment would affect the fatty acid content of Zajiao rapeseed. The fatty acid content of Fengyou No.10 rapeseed was not affected by the growing environment. For Zajiao rapeseed and Fengyou No.10 rapeseed, there was no significant difference between the same varieties of rapessed coming from different areas in fatty acid content as long as the planting environment was the same. |
