紫薇籽油脂肪酸组成的GC_MS分析_黄建民 . The Fatty Acid Composition of Lagerstroemia indica Seed Oil Determined by GC/MS

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.
