Abstract

Borage seed oil (BSO; Borago officinalis L.) has great medicinal and nutritional potential owing to its bioactive components. In this study, we compared the lipid composition, micronutrient content, free radical scavenging capacities, and cellular antioxidant and antiproliferative activities of BSO from eight provinces in China. The Gansu sample had the highest levels of γ-linolenic acid, accounting for 18.66%. We detected more than 17 triacylglycerols in BSO. Among micronutrients, δ-tocopherol and Δ5-avenasterol were the main components of tocopherol and phytosterol, respectively. The highest cellular antioxidant activity values were found in the Shanxi and Gansu samples; the concentration cytotoxicity 50% values were higher than 200 mg/mL, and the median effective dose ranged from 18.34 ± 0.52 to 70.65 ± 1.76 mg/mL. In addition, we tested the free radical scavenging capacity of BSO and found significant differences in antioxidant capacity between samples from different regions, and the Gansu sample had a better antioxidant capacity.

中国八省琉璃苣籽油的脂质组成、微量营养素和细胞抗氧化特性

琉璃苣籽油（BSO；Borago officinalis L.）因其生物活性成分而具有巨大的药用和营养潜力。在这项研究中，我们比较了来自中国八个省份的琉璃苣籽油的脂质组成、微量营养素含量、自由基清除能力以及细胞抗氧化和抗增殖活性。甘肃样本中的γ-亚麻酸含量最高，达到18.66%。我们在 BSO 中检测到了 17 种以上的三酰甘油。在微量营养素中，δ-生育酚和Δ5-芒甾醇分别是生育酚和植物甾醇的主要成分。山西和甘肃样品的细胞抗氧化活性值最高；浓度细胞毒性50%值均高于200 mg/mL，有效剂量中值为18.34 ± 0.52至70.65 ± 1.76 mg/mL。此外，我们还检测了 BSO 的自由基清除能力，发现不同地区样品的抗氧化能力存在显著差异，甘肃样品的抗氧化能力更强。

期刊介绍： The Journal of the American Oil Chemists’ Society (JAOCS) is an international peer-reviewed journal that publishes significant original scientific research and technological advances on fats, oils, oilseed proteins, and related materials through original research articles, invited reviews, short communications, and letters to the editor. We seek to publish reports that will significantly advance scientific understanding through hypothesis driven research, innovations, and important new information pertaining to analysis, properties, processing, products, and applications of these food and industrial resources. Breakthroughs in food science and technology, biotechnology (including genomics, biomechanisms, biocatalysis and bioprocessing), and industrial products and applications are particularly appropriate. JAOCS also considers reports on the lipid composition of new, unique, and traditional sources of lipids that definitively address a research hypothesis and advances scientific understanding. However, the genus and species of the source must be verified by appropriate means of classification. In addition, the GPS location of the harvested materials and seed or vegetative samples should be deposited in an accredited germplasm repository. Compositional data suitable for Original Research Articles must embody replicated estimate of tissue constituents, such as oil, protein, carbohydrate, fatty acid, phospholipid, tocopherol, sterol, and carotenoid compositions. Other components unique to the specific plant or animal source may be reported. Furthermore, lipid composition papers should incorporate elements of yeartoyear, environmental, and/ or cultivar variations through use of appropriate statistical analyses.
