Antioxidant, Antibacterial activity and Brine shrimp toxicity test of some Mountainous Lichens from Nepal
A total of twenty four lichen species belonging to six families were collected from mountainous region of Nepal. The methanol extracts of each species were tested for antimicrobial and antioxidant activitiesin vitro. It was found that extracts of twenty one lichen species were active againstB. subti...
