Abstract: (Show)
In this study, 71 species of edible medicinal plants belonging to 49 families were identified. These medicinal plants (beside therapeutic applications in Sowa Rigpa medicine) are used as food, fruit and vegetables in Bhutan. Five Himalayan medicinal plants were further studied for their phenolic content and antioxidant activity. Hypecoum leptocarpum Hook. f. & Thompson contained maximum phenolic content. The antioxidant activities were determined by DRSA and FRAP assays from water and methanol extracts. Overall, among five plants investigated, Lepisorus contortus (Christ) Ching, H. leptocarpum and Podophyllum hexandrum Royle gave good yield of phenolics content and best antioxidant activity. This study demonstrates that edible medicinal plants could be a potential source of natural antioxidants that can boost the immune system.
