Technological Evaluation of Emulsions Containing The Volatile Oil from Leaves of Lour.

Background: Lour is a species which is widespread throughout tropical countries where it is widely used against respiratory tract disorders such as bronchodilator, antitussive, and expectorant conditions.

Objective: This study aims to characterize the essential oil of (PaEO) and produce and evaluate emulsions containing PaEO.

Materials And Methods: The essential oil was characterized by physical-chemical analyses for density, refractive index, 90% ethanol solubility, color, appearance, and identification by gas chromatography coupled to mass spectrometry detection.
