چکیده انگلیسی
Ethyl acetate extracts of seaweeds were chromatographically fractionated to yield 14-methyl pentyl tetrahydro-8-hydroxy-10-methylnaphthalene-8-carboxylate (1) and tetrahydro-4-isopropyl-9-(9, 14-dimethyldec-9-enyl)-pyran-1-one (2) from Sargassum ilicifolium, whereas Padina gymnospora afforded dihydro-2-(10-(hydroxymethyl)-7,15-dimethyl-9-oxoundec-11-enyl)-2-methyl-2H-pyran-1(4H)-one (3) and 1-(decahydro-1-hydroxy-7-methyl-8-vinylnaphthalen-2-yl)ethanone (4) as major constituents. Compound 1 displayed significantly higher antioxidant activity (IC50â¯<â¯1â¯mg/mL, pâ¯<â¯0.05) comparable to other analogues (IC50â¯>â¯1â¯mg/mL). The C20-22 polyunsaturated fatty acid (C20-22 PUFA) concentrate (CFA) prepared from the deep-sea dogfish liver oil was added with the studied compounds and physiochemical properties and fatty acid composition during an accelerated storage were evaluated. No significant reduction in C20-22 PUFAs (â¼6%) in the CFA treated with 1 as compared to that with the control (â¼35%) was recorded. A greater induction time was observed for the CFA supplemented with 1 (6.8â¯h) than other compounds (â¤6â¯h) and control (â¼1.6â¯h), maintaining the oxidation indices of the CFA within desirable limits.
