Medical plants have received a lot of attention lately for preserving human health due to their less adverse effects. Phytochemical metabolites are what give traditional plants their medicinal qualities. This paper examines the ultrasonic parameters of Jatropha leaf extract in n-hexane, a non-polar solvent. The structural alterations linked to molecule interaction in liquid mixtures are shown by variations in ultrasonic velocity and associated parameters like as viscosity, acoustic impedance, adiabatic compressibility, intermolecular free length, and relaxation time.
