Antioxidant activity of Grewia villosa
Oxidative stress is one of the main cause in improvement of side effects and infectious conditions in body. So, there is a need to identify more antioxidants to reduce oxidants and their easy availability. Natural resources like medicinal plants are easily available sources as antioxidants because of their edibility and less side effects. In this point of view, the present work was carried out to identify antioxidant activity of Grewia villosa root part and preliminary phytochemical analysis. The antioxidant activity was carried out on superoxide, hydroxyl and DPPH free radical for ethyl acetate and hydro-alcoholic extracts of Grewia villosa root. The extracts of Grewia villosa showed presence and absence of different phytochemical constituents and showed concentration dependent percentage reduction on tested free radicals. The hydro-alcoholic extract showed more activity compared to ethyl acetate extract and the extract showed more activity on DPPH free radical compared to other free radicals. The current research confirms antioxidant activity of Grewia villosa root extracts and further research is worth full to identify responsible bioactive compounds from these extracts on reduction of oxidative stress and other harmful diseases.
