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。
The radish seed oils rich in isothiocyanate were extracted with dichloromethane from eight kinds of radish seeds. The fatty acid composition, sulforaphene content and antioxidant activity of the oils were analyzed. The results showed that the oil yield was 34.65% -37.91%, and there were many fatty acids in the oils and the main fatty acid were mustard acid（29.45% -35.01% ）, oleic acid （21.99% - 29.59% ）, linoleic acid（9.53% - 13.63% ）, eicosadienoic acid（8.88% - 10.52% ）, linolenie acid （5.30% -8.35% ）, palmitic acid （5.37% -5.92% ）, and the unsaturated fatty acid was 88.08% - 89.73%. The sulforaphene content in the oils was 28.39 -114.73 mg/kg, and that of the Baiyuchun radish seed oil was the highest, the sulforaphene content in the spring radish seed oils were higher than that of the autumn radish seed oils. In the test of FRAP, the Shengfeng radish seed oil showed the highest antioxidant activity.
