The effects of the lichenicolous fungus Heterocephalacria bachmannii on the antimicrobial potential of the lichen Cladonia foliacea demonstrated that the extracts investigated have antimicrobial potential against gram-positive and negative bacteria, and yeast, and inhibit the germination of fungal spores. Inhibition activity varied considerably depending on the extract, the bacterial species, and the absence or presence of H. bachmannii; unparasitised C. foliacea has a higher antimicrobial activ...

The phenolic composition and antioxidant capacity of four Tunisian lichen species, Cladonia rangiformis, Flavoparmelia caperata, Squamarina cartilaginea and Xanthoria parietina, were determined in order to provide a better understanding of their lichenochemical composition. Powdered material of F. caperata was the richest in total phenolic content (956.68 μg GAE g-1 DW) and S. cartilaginea in proanthocyanidin content (77.31 μg CE g-1 DW), while the acetone extract of X. parietina showed the high...

Since lichens have been recognised as a potential natural source of bioactive substances, the aim of this study was to investigate the antimicrobial, lysozyme and antifungal effects of methanol, acetone and quencher extracts from four lichens: Diploschistes ocellatus, Flavoparmelia caperata, Squamarina cartilaginea and Xanthoria parietina. The results showed that the tested extracts had antimicrobial activity against Gram-positive and Gram-negative bacteria and anti-candida, and inhibit the spor...

: This study, the first to assess the total phenolic, flavonoid, tannins, and proanthocyanidin content of the Tunisian lichen Diploschistes ocellatus, determined the antioxidant capacity in scavenging 2,2 diphenyl-1-picrylhydrazyl (DPPH), as well as the ferric-reducing and iron-chelating powers. The phenolic compound content of D. ocellatus was shown to be related to antioxidant activity. The highest phenolic and flavonoid contents of extracts were obtained with acetone (286.3 μg GAE/g DW and 3....
