A limited number of mosses have ever been studied in regard to antioxidant activity, with only a few belonging to the European species. As part of our ongoing screening of bryo- phytes as natural antioxidant resources, a relevant biological activity investigation was conducted on three moss species, namely Brachythecium rutabulum (Hedw.) Schimp. (Bra- chytheciaceae), Calliergonella cuspidata (Hedw.) Loeske (Hypnaceae) and Hypnum mam- millatum (Brid.) Loeske (Hypnaceae), collected in Germany. The antioxidant activity of cor- responding aqueous extracts was evaluated on the basis of their ABTS (2,2'-azino-bis(3- -ethylbenzthiazoline-6-sulphonic acid)) cation scavenging activities. The total phenolic con- tents were determined as well. This study led to the detection of a moderate total phenolic content of the moss B. rutabulum, indicating for the first time its potential in searching for novel antioxidant agents
