Phenolic acids in the genus Lycopodium
Abstract
The dihydric phenolics from the leaves of 170 Ecuadorian Lycopodium specimens representing 49 species and varieties have been examined as semiquinones by EPR spectroscopy. An ester of dihydrocaffeic acid was observed in 137 extractors of specimens all confined to the subgenus Urostachya. The ester was not present in the subgenera Lycopodium and Lycopodiella, where the dominant phenolic acid was chlorogenic acid. The concentrations of the "Urostachyaester" were found to increase with increasing altitude. Hydroquinone and protochatechuic acid have been observed in a few specimens.
