It is used as a cure for diarrhoea, dysentery, cholera, burns, boils, high blood pressure, sprains and body pains. Silver and gold nanoparticles were synthesized from the extracts of the leaves of this plant as the some biomolecules, known as secondary metabolites, present in plant extracts can be used to reduce metal ions to nanoparticles. The contents of the leaves were extracted in various solvents and the tests for the presence of secondary metabolites were carried out. The gold and silver nanoparticles synthesized using the plant extracts and characterized using TEM, SEM techniques and the phytochemical screening tests were done for different extracts. The anti-oxidant studies of the several extracts were carried out. (C) 2020 Elsevier Ltd.
