ABSTRACT: Antioxidant capacities and phenolic contents of medicinal plants namely Usnea
longifolia, Cetraria nepalensis, Parmelia 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 differences (P R. anthopogon among
the plants tested.
