Extraction of essential oils from two forest species and two shrub species to determine their properties under laboratory conditions

Abstract

The philosophy of forestry engineering should not be solely focused on planning and executing forestry exploitation systems, but rather give emphasis as an alternative to environmental conservation to research into the extraction of essential oils that are useful in the industry. medicine, phytotherapy, perfumery, etc. Objectives: The objective of this research was to obtain essential oils from the forest species of Eucalyptus, Molle, edematous shrub species such as Rosemary and Cedrón, the determination of their composition. Using the steam extraction oil extraction technique, the following Results: The yield of Eucalyptus was 12%; Molle 7%; Kidron 2%; Rosemary 0.60%; Using the fine chromatography technique, it was determined that Eucalyptus has 0.39% Cineol; 0.50% Pinene, 0.65% Terpineol; Molle presents 0.23% Terpineol, 0.38% Phelandrene, 0.50% Methyl Pentanol; Rosemary presents 0.45% Pinene, 0.60% Cineol, 0.70% Bromeol, 0.82% Camphor; El Cedrón presents 0.48% Citral, 0.55% Berona. Conclusions: Essential oils are volatile phenolic and aromatic compounds, they have different degrees of refraction, specific weight, concentration, and purity, they are made up of organic molecules, presenting a different structure and special arrangement.
