基于文献分析的中国猕猴桃属植物亚麻酸资源研究

Research on Linolenic Acid Resources from Actinidia Plants in China Based on Literature Analysis

通过调查和文献整理,对中国猕猴桃属植物资源中含α-亚麻酸的猕猴桃种类、分布特点以及α-亚麻酸含量、提取方法进行统计分析。结果表明,我国已报道富含亚麻酸的猕猴桃属共有11个物种、10个栽培品种;富含α-亚麻酸的猕猴桃植物资源主要分布在长江流域,少量分布在东北和西南地区;猕猴桃籽油中α-亚麻酸含量总体集中在40%~70%之间,属于高含量亚麻酸资源植物;不同提取方法对猕猴桃亚麻酸的提取效果有较大影响,以尿素包合法和分子蒸馏技术分离纯化的提取效果较好,提取的α-亚麻酸含量高达87.20%。

The species and distribution of Actinidia enriched in α-linolenic acid, content and extraction methods of α-linolenic acid in Actinidia were summarized. In China, there were 11 species and 10 cultivars of Actinidia enriched in α-linolenic acid. Most species distributed in Yangtze River, only a few in northeast and southwest regions of China. Seed oil of Actinidia showed relative high content of α-linolenic acid （about 40%-70% of total fatty acids）. Importantly, different extraction methods had great influence on extraction effect of α-linolenic acid. The content of α-linolenic acid separated and purified by Urea adduction fractionation and molecular distillation was up to 87.20%.
