Antioxidant capacities and phenolic contents of medicinal plants namely Usnea longifolia , Cetraria nepalensis , Par melia minarum , Everniastrum nepalense , Rhododendron anthopogon and Fritillaria delavayi were analyzed via Folin- Ciocaltau assay, Ferric reducing activity power assay and 2,2-Diphenyl-1-picrylhydrazyl assay. All the tested plants depicted the antioxidant activity with variation in extent of activity among the plants. The FRAP (F-value: 387.4), DPPH (F-value: 89.684) and TPC (F-value: 559.163) values between the extracts showed the highly significant differ ences ( P < 0.01). This study indicated the strong antioxidant potential of R. anthopogon among the plants tested .
