Abstract

Fifty Ribes species and R. nigrum-based cultivars from eight Ribes sections were surveyed for γ-linolenic acid (GLA, 18:3, n-6)- and stearidonic acid (SDA, 18:4, n-3)-rich oils. R. pallidiflorum, R. glabellum and R. pubescens seed oils contain noticeable GLA amounts: 13.3, 11.8, and 11.9% of total fatty acids (FA), respectively. However, the highest GLA contents were found in the seed oils of several blackcurrant cultivars, highlining Ribes 'Myuryucheene' with 20.2% GLA of total FA. Principal Component Analysis showed that similarities in FA profiles allow grouping species as botanical criteria for Ribes sections do. The main GLA-taxa detected in this study correspond to blackcurrant cultivars, all of them native to Siberia. Considering that such cultivars are notable fruit-producers, its cultivation in Siberia besides producing fruits in very difficult agronomic areas, could produce a valuable by-product, i.e. the seeds, which will add economic value to agricultural systems if devoted to GLA-rich oils extraction.

摘要

对来自 8 个 Ribes 节的 50 种 Ribes 物种和基于 R. nigrum 的栽培品种进行了γ-亚麻酸（GLA，18:3，n-6）和硬脂酸（SDA，18:4，n-3）丰富油的调查。R. pallidiflorum、R. glabellum 和 R. pubescens 的籽油含有可观的 GLA 含量：分别为总脂肪酸（FA）的 13.3%、11.8%和 11.9%。然而，几种黑加仑栽培品种的籽油中发现了最高的 GLA 含量，Ribes 'Myuryucheene'的 GLA 含量最高，占总 FA 的 20.2%。主成分分析表明，脂肪酸图谱的相似性允许根据植物学标准将物种分组，这与 Ribes 节的分类标准一致。本研究中检测到的主要 GLA 类群与黑加仑栽培品种相对应，它们都原产于西伯利亚。考虑到这些栽培品种是显著的水果生产者，如果在西伯利亚种植，除了在非常困难的农业地区生产水果外，还可以生产一种有价值的副产品，即种子，如果用于提取富含 GLA 的油，将为农业系统增加经济价值。
