长林系列油茶籽含油率和脂肪酸组成分析研究

Analysis of Oil Content and Fatty Acid Composition of Changlin Series Camellia oleifera's Seeds

对长林系列11个油茶良种油茶籽含油率进行了测定,并采用GC/MS分析油茶籽油的脂肪酸组成结果表明：油茶籽含油率大部分集中在30%-45%,平均含油率为37.94%;含油率最高为46.41%,最低为22.80%。油茶籽油脂肪酸主要由油酸、亚油酸、棕榈酸、硬脂酸等9种脂肪酸组成;油酸含量为71%-78.96%,均值为74.82%,标准偏差为2.72%。亚油酸含量在7.02%-14.3%,均值为11.49%,标准偏差为2.59%。棕榈酸含量在8.75%-11.80%,均值为9.94%,标准偏差为0.98%;硬脂酸含量在1.66%-3.79%,均值为2.57%,标准偏差为0.71%。

The oil contents of Changlin series Camellia oleifera＇s seeds from 11 varieties were determined, and the fatty acid compositions of the C. oleifera seeds＇ oil were analyzed by GC/MS. The results indicated that： the oil content was between30% and 45%, and the average oil content was 37.94%; the highest oil content was 46.41%, and the lowest oil content was22.80%. The fatty acid was mainly composed of oleic acid, linoleic acid, palmitic acid, stearic acid and other 5 kinds of fatty acid. The content of oleic acid was 71%-78.96%, and the average value was 74.82%, the standard deviation was 2.72%; the content of linoleic acid was 7.02%-14.3%, and the average value was 11.49%, the standard deviation was 2.59%; the content of palmitic acid was 8.75%-11.80%, and the average value was 9.94%, the standard deviation was 0.98%; the content of stearic acid was 1.66%-3.79%, and the average value was 2.57%, the standard deviation was 0.71%.
