摘要
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 < 0.01). This study indicated the strong antioxidant potential of R. anthopogon among the plants tested.
