摘要
Antioxidant potential of three brown seaweeds, Anthophycus longifolius, Sargassum plagiophyllum, and Sargassum myriocystum, obtained from the Gulf of Mannar region of India were evaluated utilizing different in vitro systems. Ethyl acetate (EtOAc) fraction of Anthophycus longifolius registered significantly greater hydroxyl radical scavenging ability (IC50 0.19 mg/mL) and was effective in stabilizing the 2,2′-azino-bis-3-ethylbenzothiozoline-6-sulfonic acid (IC50 1.23 mg/mL) and 1,1-diphenyl-2-picryl-hydrazil (DPPH) radicals (IC50 0.48 mg/mL) (p < 0.05). No significant differences in hydrogen peroxide (H2O2) scavenging and ferrous ion chelating properties of the EtOAc extracts of the seaweeds were apparent. The utilities of the reverse-phase high-performance liquid chromatography (RP-HPLC) method hyphenated to diode-array detection for analyzing the fingerprints of phenolic constituents in the solvent extracts and fractions of the seaweeds were denoted. High-performance liquid chromatographic analysis indicated the presence of phenolic acids in the solvent extracts of seaweeds. This study demonstrated the potential use of A. longifolius as candidate species to be used as a nutritional food supplement/functional foods to increase the shelf life of food items for human consumption.

三种褐藻，Anthophycus longifolius，Sargassum plagiophyllum和Sargassum myriocystum的抗氧化潜力，使用不同的体外系统评估从印度曼纳尔湾获得的。Anthophycus longifolius的乙酸乙酯（EtOAc）级分具有显着更大的羟自由基清除能力（IC 50 0.19 mg / mL），有效稳定了2，（IC 50 1.23mg / mL）和1,1-二苯基-2-吡啶基 - 肼（DPPH）基团（IC 50 0.48mg / mL）（p 0.05）。海藻的EtOAc提取物的过氧化氢（H 2 O 2）清除和亚铁离子螯合性质没有显着差异。表征了溶剂提取物和海藻馏分中酚类成分指纹图谱的二联体阵列检测方法。高效液相色谱分析表明在海藻溶剂提取物中存在酚酸。本研究证明了A的潜在用途。longifolius作为候选物种用作营养食品补充剂/功能性食品，以增加人类消费食品的保质期。
