Physical Characterization-Chemistry of Essential Oil of Oregano in 6 Communities of the Municipality of Rodeo, Dgo.

Abstract

The municipality of Rodeo is one of the largest oregano producers in the state of Durango, reporting an average of 100 tons per year, which are used as a condiment and there is no use in its entirety. The objective of the present work was Physicochemical Characterization of Essential Oil of Oregano (AEO) in 6 communities of the municipality of Rodeo Durango, the methodology was carried out by dragging with water vapor, where quality and quantity of oil were controlled, using the leaves of The oregano plant, the density, was determined by means of a pycnometer and the index of refraction by means of a refractometer (Master Refractometer). The results obtained for the index of refraction of the oils of the 6 localities circle between 1.47-1.50 which indicates an acceptable purity in the (AEO). The density of oils circle between 0.91-0.92. The chemical components were read by gas chromatography and a Flame Ionization Detector (FID), where a higher percentage of concentration on the carvacrol compound was reported, which circulated between 60-70% while the compound Thymol was between 30-40%. A statistical analysis was performed to determine if there was a significant difference between the concentration of the analytes based on the height of the sample obtaining a significance >5, which indicates a difference between the data.
