Fig. 5From: Screening and characterization of bioactive compounds from two epiphytic microlichen and evaluation of their in vitro antioxidant activityA DPPH radical scavenging activity of Pyrenula nitida was carried out by taking 100–1000 μg/ml concentration of lichen extract in X-axis and scavenging activity (% of inhibition) in Y-axis, butylated hydroxy toluene (BHT) represented as standard. B DPPH radical scavenging activity of Graphis scripta was carried out by taking 100–1000 μg/ml concentration of lichen extract in X-axis and scavenging activity (% of inhibition) in Y-axis, butylated hydroxy toluene (BHT) represented as standardBack to article page
