Synthesis of hesperetin nanoparticles
A method of preparing hesperetin nanoparticles includes dissolving hesperetin in an organic solvent to form a solution; spraying the solution in boiling water while applying ultrasonic energy to form a mixture; and stirring the mixture for at least about 15 minutes at a speed of about 200-800 rpm to obtain the hesperetin nanoparticles.
