【摘要】 为了开发和利用紫薇籽油,采用冷榨法从紫薇种子中榨取了油脂,并采用GC/MS对堇薇、红薇、银薇3个不同品种群紫薇籽油的脂肪酸组成进行了测定。分析结果表明,不同品种群紫薇籽油均含有相同的17种脂肪酸,不同品种群脂肪酸含量有差异,其中堇薇品种群不饱和脂肪酸总含量最高,为86.57%,该品种群饱和脂肪酸总含量最低,为13.05%;不饱和脂肪酸的主要成分是亚油酸和油酸,其中亚油酸含量最高,堇薇、红薇、银薇3个品种群亚油酸含量分别为71.62%、70.91%、72.87%;从紫薇籽油中检测出奇数碳脂肪酸类二十三烷酸,该脂肪酸具有抗癌活性,表明紫薇籽油是一种值得开发的保健油脂。更多还原

【Abstract】 The Lagerstroemia indica was an important flower species in summer,which was widely cultivated in China.In order to develop and use L.indica seed oil,cold pressed method was used to extract the oil from the L.indica seed,the fatty acids composition of the seed oil of L.indica Amabilis Group,L.indica Rubra Group and L.indica Alba Group were determined by GC/MS.The results showed that different varieties of L.indica seed oil contained the same 17 kinds of fatty acids;there were differences between the fatty acid content of different variety groups.The total unsaturated fatty acids content of L.indica Amabilis Group was highest,which content was 86.57%;the total saturated fatty acid content of L.indica Amabilis Group was lowest,which content was 13.05%.The main components of the unsaturated fatty acid were oleic acid and linoleic acid.The linoleic acid content of L.indica Amabilis Group,L.indica Rubra Group and L.indica Alba Group were 71.62%,70.91% and 72.87% respectively.The odd number carbon fatty acids which had antitumor activity were determined out from L.indica seed oil.It indicated that L.indica seed oil was health oil that worth to develop.更多还原
