摘要：

为了研究油茶生长发育过程中脂肪含量及脂肪酸成分的变化，分析测定2个油茶品种在不同生长时期油茶籽中的脂肪酸成分。采用索氏提取法提取油茶籽中的脂溶性成分，经甲酯化处理后用气象色谱分离和鉴定，运用面积归一法确定各成分的相对百分含量。结果表明，在整个发育过程中油脂形成有两个高峰，分别在9月上旬和10月上旬；种子种脂肪酸的主要组成是不饱和脂肪酸，油酸含量最高，其次是亚油酸和油酸，饱和脂肪酸以棕榈酸和硬脂酸为主，其中油酸呈明显上升趋势，棕榈酸和亚油酸呈明显下降趋势，硬脂酸呈小幅上升趋势，亚麻酸呈小幅下降趋势。

Abstract:

The aim was to research the changes of fat content and fatty acid composition in the growth and development of Camellia. The fatty acids compositions of two oil-tea species in different growth stages of camellia seeds were analyzed and determined in this present. The fat-soluble ingredients of camellia were extracted using the Soxhlet extractor. Then the fatty acids compositions were separated and analyzed after methyl processing meteorological by gas chromatograph, using area normalization method to determine the relative contents of each ingredient. The results indicated that there were two peaks of grease forming in the whole development process, in early September and early October, respectively. The main components of seed fatty acids are unsaturated fatty acids, and the content of oleic acid were the highest in the unsaturated fatty acids of them, followed by linoleic acid and oleic acid. Saturated fatty acids main had palmitic acid and stearic acid, while oleic acid was obviously a rising trend, palmitic acid and linoleic acid showed a downward trend clearly, stearic acid showed a slight upward trend, linolenic acid showed a slight downward trend.
