In vitro study on screening antimicrobial and anti-oxidant potential of Ramalina fastigiata
The aim of the present study is to investigate the antimicrobial and anti-oxidant potential of lichen Ramalina fastigiata collected from Kolli hills, Eastern Gahts of Tamil Nadu, India. Phytochemical study revealed that acetone extract of Ramalina fastigiata confirmed the presence of flavonoids, glycosides and phenols. Acetone extract of Ramalina fastigiata was tested against human pathogens, which exposed antimicrobial activity against Klebsiella pneumonia and Candida krusei with the inhibition rate of 2.1 mm and 1.3 mm respectively. The acetone extract of lichen Ramalina fastigiata exhibited significant antioxidant activity as well. Radical scavenging ability of Ramalina fastigiata was reported in terms of 61.53 % inhibition.
