Biological Activities
Compounds
Blechnum tabulare, also known as Lomariocycas tabularis, has been identified as one of the rare fern species containing rosmarinic acid. This specific phenolic compound was found in only four investigated species belonging to the Blechnoideae subfamily. The presence of such derivatives is significant, as these compounds often contribute to the medicinal properties of various land plants. While caffeoyl-5-O-quinic acid was found across all studied species, the distribution of rosmarinic acid remains relatively limited within the Blechnaceae family. These findings highlight the complex chemical diversity present in ferns, a group that remains largely under-investigated regarding its natural products.
