Abstract

Phytochemicals in the medicinal plants are actually responsible for their healing properties in traditional practices. Present study assessed the antioxidative potential and phytochemical constituents in the leaf and stem extracts of Viburnum cotinifolium D. Don, Isodon rugosus (Wall. ex Benth.) Codd, Cotoneaster microphyllus Wall. ex Lindl., and Lonicera angustifolia Wall. ex DC. growing in the wild in Himachal Pradesh. Phytochemical screening confirmed the presence of important secondary metabolites such as flavonoids, phenols, tannins, cardiac glycosides, terpenoids, steroids, saponins, and proteins in all the test plants. C. microphyllus showed the presence of a highest amount of total phenolic content in both leaf and stem amongst all the plants analyzed. It also exhibited the maximum quantity of total flavonoid and tannins. Extract of all the plants confirmed concentration-dependent DPPH free radical scavenging and reduction of Fe3+ to Fe2+ in the reducing power assay. This study corroborates vitality of these plants being used consistently in the herbal medicines.
