【摘要】Objective:To develop a novel approach for the green synthesis of silver nanoparticles using aqueous leaves extracts of Catharanthus roseus(C.roseus) Linn.G.Don which has been proven aclive against malaria

parasite

Plasmodium

falciparum(P.falciparum).Methods:Characterizations were determined by using ultraviolet-visible(UV-Vis) spectrophotometry,scanning electron microscopy(SEM).energy

dispersive

X-ray

and

X-ray

diffraction.Results:SLM showed the formation of silver nanoparticles with an average size of 35-55 nm.X-ray diffraction analysts showed that the particles were crystalline in nature with face centred cubic structure of the hulk silver with the broad peaks at 32.4.46.4 and 28.0.Conclusions:It can be concluded that the leaves of C.roseus can he good source for synthesis of silver nanoparticle which shows aiitiplasmodial activity against P.falciparum.The important outcome of the study will he the development of value added products from medicinal plants C.roseus lor hionicdical and nanotechnology based
