摘要

目的 研究杜仲籽中主要脂肪酸的积累过程。方法 采用气相色谱法对华仲6号杜仲种子发育过程中脂肪酸组分的变化进行了检测分析。结果 杜仲种子中脂肪酸主要由棕榈酸、硬脂酸、油酸、亚油酸和α-亚麻酸5种成分组成,α-亚麻酸含量最高,其次是油酸,含量最低的是硬脂酸。结论 种子发育过程中,棕榈酸和油酸在籽粒发育初期含量较高,但随着籽粒的逐渐发育成熟却下降,硬脂酸也随着籽粒的逐渐发育成熟而下降,亚油酸和α-亚麻酸则随着籽粒发育成熟其含量呈上升趋势。

Abstract

OBJECTIVE To study the accumulation process of main fatty acids in Eucommia ulmoides seeds. METHODS Gas chromatography was used to determine the change of the fatty acid composition in Huazhong No.6 Eucommia ulmoides seeds in the process of development. RESULTS The fatty acids in Eucommia ulmoides seeds were mainly composed of palmitic acid, stearic acid, oleic acid, linoleic acid, and α-linolenic acid, among which α-linolenic acid had the highest content followed by oleic acid, and stearic acid had the lowest one. CONCLUSION During seed development, the contents of palmitic acid and oleic acid are higher in the early period of grain development, but gradually drop with the maturation of the grains. The content of stearic acid also declines with the gradual maturation of the grain. On the contrary, the contents of α-linolenic acid and linoleic acid keep rising as the grains mature.
