Abstract
The olive leaf extract silver nanoparticles may be synthesized by extracting olive leaves and using the extract to synthesize AgNPs. Olive leaves may be washed, dried, and ground to a powder. The olive leaf powder may be mixed with a first solvent to form a first olive leaf extract. The first olive leaf extract may then be separated and/or concentrated by centrifugation and filtration to form a filtrate. The filtrate may be evaporated to form a residue. The residue may then be resuspended in ethanol to form a second olive leaf extract. The second olive leaf extract may be mixed with AgNO3 to form a mixture including the AgNPs.
Claims11
A method of synthesizing olive leaf extract silver nanoparticles, comprising:
- providing olive leaves;
- grinding the olive leaves to provide an olive leaf powder;
- mixing the olive leaf powder with a first solvent to form a first olive leaf extract;
- concentrating the first olive leaf extract to provide a filtrate, wherein concentrating the first olive leaf extract to provide a filtrate comprises:
- i) centrifuging the first olive leaf extract at about 16,000×G, at a temperature of 4° C., for about 10 minutes to provide a pellet;
- and
- ii) filtering the pellet through a 0.45 μm syringe filter to provide the filtrate;
- evaporating the filtrate to provide a residue;
- dissolving the residue in a second solvent to provide a final olive leaf extract;
- and
- mixing the final olive leaf extract with AgNO3 to form a mixture including the silver nanoparticles.
