Abstract
The present study was carried to evaluate antioxidant and antibacterial activity of two macrolichens Parmotrema pseudotinctorum (des. Abb.) Hale and Ramalina hossei H. Magn & G. Awasthi individually and in combination with honey. The powdered lichen materials were extracted with methanol solvent. Antioxidant activity was assessed using DPPH free radical scavenging assay and antibacterial activity was determined by performing Agar well diffusion method. Antioxidant activity of combination of honey and lichen extracts was not as effective as scavenging potential of individual lichen extracts. Extracts of P. pseudotinctorum and R. hossei exhibited marked antibacterial activity individually than in combination with honey. Among all, honey showed less antioxidant and antibacterial activity. Thus, combination of lichen extracts and honey was not found to exert any synergistic action.
