Particulate matter is a major contribution of air pollution and detrimental to human health. The in vitro antioxidant activities of a brown seaweed, Sargassum horneri ethanol extract (SHE) against particulate matter-induced oxidative stress were investigated by measuring 1,1-diphenyl-2-picrylhydrazyl (DPPH) free-radical scavenging activity, hydrogen peroxide (H2O2) scavenging activity, superoxide anion (O·2) inhibition, hydroxyl radical (·OH) scavenging activity, reducing power, and the metal ion-chelating effect. All in vitro antioxidant activities were increased as the concentration of SHE increased (0–1000 μg/mL). When treated with particulate matter at 0–1000 μg/mL, the DPPH free radical, and H2O2 scavenging activities, reducing power, and metal ion-chelating abilities of SHE were significantly decreased (p < 0.05). These results indicate that Sargassum horneri, which is a rich source of bioactive compounds, can be used as a natural source of antioxidants in the food industries.

马尾藻提取物对城市颗粒物引起的氧化的抗氧化潜力。



颗粒物是空气污染的主要来源,对人类健康有害。通过测量 1,1-二苯基-2-三硝基苯肼 (DPPH) 自由基清除活性、过氧化氢 (H 2 O 2 )清除活性、超氧阴离子(O · 2 )抑制、羟自由基( · OH)清除活性、还原力和金属离子螯合作用。所有体外抗氧化活性均随着 SHE 浓度(0-1000 μg/mL)的增加而增加。当用0-1000 μg/mL的颗粒物处理时,SHE的DPPH自由基和H 2 O 2清除活性、还原力和金属离子螯合能力显着降低( p < 0.05)。这些结果表明,马尾藻是生物活性化合物的丰富来源,可以用作食品工业中抗氧化剂的天然来源。
