γ-linolenic acid (GLA, 18:3n-6) is a bioactive fatty acid (FA) that exerts several healthy actions; however, its occurrence is restricted to a few oils. The goal of this study was to detect GLA-rich Ribes species and cultivars (cv), and to achieve this the seeds of 7 Ribes taxa and 50 Ribes cv were surveyed for FA profiles. The highest GLA percentages were found in R. nigrum cv 'Plotnokistnaya', 'Volshebnica', 'Atlant' and 'Nara' (22.6, 22.1, 20.9, and 20.0% of total FA, respectively) and also in R. komarovii (19.6%) and R. nigrum var. sibiricum (18.3%). Stearidonic acid (SDA, 18:4n-3) had the highest values in both R. rubrum 'Konstantinovskaya' and R. niveum 'Smolyaninovskaya' (4.8%). GLA content ranged from 0.4 in some R. rubrum cv and R. niveum 'Smolyaninovskaya' to 3.5 g/100 g seeds in R. nigrum 'Plotnokistnaya'. Principal component analysis (PCA) was performed using PUFA profiles, which allowed grouping Ribes sections as well as black currant cv derived from different pedigree within the section Coreosma. All taxa and cv checked here are valuable by-product sources, given the high GLA percentages contained in their seed oils. Such cv could be used for healthy oils production, as well as for breeding to obtain new cv with improved GLA concentrations.

来自五十七种葡萄品种和栽培品种的γ-亚麻酸

γ-亚麻酸 (GLA, 18:3 n -6) 是一种具有多种健康作用的生物活性脂肪酸 (FA)；然而，它的出现仅限于少数油。本研究的目的是检测富含 GLA 的Ribes物种和栽培品种 (cv)，并为此对 7 个Ribes分类群和 50 个Ribes cv的种子进行 FA 概况调查。在R. nigrum cv 'Plotnokistnaya'、'Volshebnica'、'Atlant' 和 'Nara'（分别占总 FA 的 22.6、22.1、20.9 和 20.0%）和R. komarovii（19.6 ）中发现了最高的 GLA 百分比%) 和R. nigrum var 。西伯利亚(18.3%)。硬脂酸 (SDA, 18:4 n-3) 在R. rubrum 'Konstantinovskaya' 和R. niveum 'Smolyaninovskaya'中均具有最高值(4.8%)。GLA 含量范围从一些红色红蔷薇cv 和R. niveum 'Smolyaninovskaya' 中的0.4到R. nigrum 'Plotnokistnaya' 中的3.5 g/100 g 种子。使用 PUFA 配置文件进行主成分分析 (PCA)，这允许对Ribes部分以及来自Coreosma部分内不同谱系的黑醋栗 cv 进行分组. 鉴于种子油中含有高 GLA 百分比，此处检查的所有分类群和 cv 都是有价值的副产品来源。这种 cv 可用于健康的油生产，也可用于育种以获得具有改进 GLA 浓度的新 cv。
