A limited number of mosses has ever been studied regarding antioxidant activity among which only a few are European species. As a part of our ongoing screening of new promising bryophyte resources of natural antioxidants, a relevant biological activity investigation was conducted on the moss Bryum moravicum Podp. (Bryaceae) collected in Germany. The antioxidant activity of an aqueous extract of the species was evaluated in vitro by analysing its ABTS [2,2'-azino-bis(3-ethylbenzthiazoline-6-sulphonic acid)] cation scavenging activity and total phenolic content. The study led to the detection of a moderate antioxidant activity: 1 mg of the extract was equivalent to 84.56 ± 7.93 µg of ascorbic acid. The total phenolic content in 1 mg of the extract was equivalent to 356.44 ± 9.56 µg of ferulic acid used as a standard. These results have indicated for the first time potential importance of B. moravicum in searching for novel antioxidant agents.
对具有抗氧化活性的苔藓植物进行了有限的研究，其中只有少数是欧洲物种。作为我们正在进行的筛选新的有前途的天然抗氧化剂苔藓植物资源的一部分，对在德国采集的藓类 Bryum moravicum Podp.（Bryaceae）进行了相关的生物活性研究。通过分析其 ABTS [2,2'-azino-bis(3-ethylbenzthiazoline-6-sulphonic acid)] 阳离子清除活性和总酚含量，评估了该物种的水提物的抗氧化活性。研究结果表明该提取物具有中等的抗氧化活性：1mg 提取物相当于 84.56±7.93µg 抗坏血酸。1mg 提取物中的总酚含量相当于 356.44±9.56µg 用作标准的阿魏酸。这些结果首次表明 B. moravicum 在寻找新型抗氧化剂方面具有潜在的重要性。
