Resumen
In last few decades, use of medicinal plants as remedial agents gain attention. The remedial properties of any plant or plant products based on their phytochemical constituents.The study of that phytochemical serve as a source of new drug development.The present paper provides information is for the first time about the investigation of Ultrasonic acoustic parameters of Ethanolic extract of leaves of Euphorbia Nivulia. Euphorbia Nivulia is thorny, xerophytic, succulent plant belong to spurge family, Euphorbiaceae. Ultrasonic studies provide valuable information about the nature of molecular interaction in binary or ternary liquid mixture. For these purpose Ultrasonic velocity, density, viscosity measured for pure liquid and its mixture with leaves extract of Euphorbia Nivulia. The acoustic parameter have been calculated from experimental data to analyse certain physiochemical properties of plant extract.
