Abstract

The antioxidant and antimicrobial properties of two Hawaiian marine algae (Ulva fasciata and Gracilaria salicornia) were evaluated. Ethanolic extracts of these two algae exhibited intracellular reactive 1,1-diphenyl-2-picrylhydrazyl, 2,2'-azino-bis(3-ethylbenzthiazoline)-6-sulfonic radical, nitric oxide, superoxide radical, and hydroxyl radical scavenging activities. In addition to the antioxidant activity these algae possessed appreciable antimicrobial activity and total phenolic contents. The overall results have established that these two marine algae could be used to derive bioactive compounds for a possible role as nutraceutical agents.

摘要

评估了两种夏威夷海洋藻类（石莼和龙须菜）的抗氧化和抗菌特性。这两种藻类的乙醇提取物表现出细胞内活性 1,1-二苯基-2-苦基肼、2,2'-联氮基-双（3-乙基苯并噻唑啉-6-磺酸）自由基、一氧化氮、超氧自由基和羟基自由基清除活性。除了抗氧化活性外，这些藻类还具有相当的抗菌活性和总酚含量。总的结果表明，这两种海洋藻类可用于提取具有潜在营养作用的生物活性化合物。
