Synthesis of adansonia digitata nanoparticles

A method of synthesizing Adansonia digitata nanoparticles, comprising:

• dissolving Adansonia digitata plant powder in an organic solvent selected from the group consisting of at least one of methanol, ethanol, dichloromethane, and chloroform to form a solution;
• adding about 1 ml to about 4 ml of the solution to about 50 ml to about 100 ml of boiling water under ultrasonic conditions to form a mixture;
• and;
• stirring the mixture at a speed of about 200 rpm to about 800 rpm to obtain Adansonia digitata nanoparticles,
• wherein the ultrasonic conditions include sonication for about 10 minutes to about 20 minutes with an ultrasonic power of 100 W and a frequency of 30 kHz prior to being stirred, and
• wherein the Adansonia digitata nanoparticles have a mean diameter in the range of from about 50 nm to about 300 nm.
