Fig. 6From: Screening and characterization of bioactive compounds from two epiphytic microlichen and evaluation of their in vitro antioxidant activityA Ferric-reducing antioxidant power assay of P. nitida was carried out taking 100–1000 μg/ml concentration of lichen extract in X-axis and reducing activity (absorbance at 700 nm) in Y-axis. The experiment was carried out in triplicate, while the error bars indicate standard deviation among the replicates. B Ferric-reducing antioxidant power assay of G. scripta was carried out taking 100–1000 μg/ml concentration of lichen extract in X-axis and reducing activity (absorbance at 700 nm) in Y-axis.
