| 中文摘要: |
| 用二氯甲烷作提取剂提取了富含异硫氰酸盐的萝卜籽油,并分析了其脂肪酸组成、莱菔素(sulforaphene)含量及抗氧化性能。结果表明:8种萝卜籽油得率为34.65%～37.91%;8种萝卜籽油中含有多种脂肪酸,其中芥酸含量最高,为29.45%～35.01%,其次是油酸(21.99%～29.59%)、亚油酸(9.53%～13.63%)和二十碳一烯酸(8.88%～10.52%),再次是α-亚麻酸、棕榈酸,含量分别为5.30%～8.35%、5.37%～5.92%,不饱和脂肪酸含量达88.08%～89.73%;8种萝卜籽油含有28.39～114.73 mg/kg的sulforaphene,其中白玉春的含量最高,春萝卜籽油比秋萝卜籽油含量相对高。FRAP法抗氧化测定中,盛丰白萝卜籽油的活性最高。 |
