Introduction

Alzheimer is a type of dementia that causes problems with memory and thinking. the most important factors of alzheimer,s disease are the accumulation of beta amyloid proteins and free radicals in the brain. the purpose of this investigation is analyzing the anti alzheimer’s properties of hydro alcoholic extract of clove leaf by anti nano amyloid fibrils and antioxidant methods.

Methods

At first, the leaves of clove were powdered and with the help of 96% ethanol, the hydro alcoholic extract of clove leaves was prepared. anti alzheimer effect of clove extract were measured with investigating by the presence of amyloid strands which done with congored spectroscopy method and by the antioxidant method which done with dpph method.

Results

After preparing the extract with a concentration of 10 mg/ml, the anti alzheimer’s properties of eucalyptus hydro alcoholic extract were measured. the highest antioxidant activity was observed at the concentration of 5 mg/ml. the anti amyloid activity was observed at the concentration of 0.4 mg / ml of extract.

Conclusion

Due to the antioxidant and anti amyloid properties of the hydro alcoholic extract of clove leaves, this medicinal herb can be a perfect alternative for preventing and treating alzheimer’s disease.
