Fatty acid composition of commercially available nutrition supplements

摘要

We analysed the fatty ac id (FA) composition of plant and fish oil supplements available in the Czech Republic. Total lipid FA composition was analysed by gas chromatography. A total of 62 plant and 50 fish oil supplements were analysed. Their FA composition ranged widely. Linoleic ac id wa s a dominant FA in soya lecithin (45–60%), e vening primrose (65–75%), amaranth (20–50%), pumpkin seed (45–55%), and borage oil supplements (40%). α-Linolenic acid ranged between 2% and 8% in soya lecithin and from 0.2% to 1% in the majority of the other plant oil supplements. Saw palmetto oil supple -ments were rich in saturated FA (40–90%). γ-Linolenic acid was found in evening primrose and borage oil supplements (10–20%). Se a buckthorn oil composition varied according to the part of the plant used. The majority of fish oil supple -ments contained 12–23% of eicosapentaenoic and 7–17% of docosahexaenoic acids. Oil supplements may be beneficial for patients with metabolic disorders because of their FA as well as antioxidant and phytosterol content
