紫苏种子脂肪酸组成及合成代谢研究进展

Research Advances on Fatty Acid Component and Fatty Acid Biogynthesis Metabolism in Perilla Seed

紫苏是一种新型油料作物,种子含油量为35%左右,紫苏籽油脂肪酸组成丰富,含有棕榈酸(16∶0)、硬脂酸(18∶0)、油酸(18∶1)、亚油酸(18∶2)和α-亚麻酸(18∶3)等,其中α-亚麻酸(ALA)含量高达60%,广泛用于功能性保健食品、药物及油脂化工业。介绍紫苏种子脂肪酸组成及合成代谢基本途径,对近年来脂肪酸合成代谢基因工程研究进行概述与展望。

Perilla is a new oil crop.The perilla seed oil takes about 35% by weight and consists of palmitic（16∶ 0）,stearic（18∶ 0）,oleic（18∶ 1）,linoleic（18∶ 2）,and α-linolenic（18∶ 3）.The content of linolenic acid is 60%,which is the highest.Perilla oil has been used for functional health food,medicine and oil chemical industry.In this paper,the fatty acid component and the basic pathway of fatty acid biosynthesis metabolism in the perilla seed were introduced,and the recent progress about the manipulation of fatty acid biosynthesis metabolism was also reviewed.
