ENRIQUEZ, M. B. y ORRABALIS, C. J.. Chemical characterization of the essential oil obtained from the wood of Bulnesia sarmientoi Lorenz ex Griseb. (palo santo) collected in Matacos department, Formosa province, Argentina. Multequina [online]. 2019, vol.28, n.2, pp.59-66. ISSN 1852-7329.
Bulnesia sarmientoi Lorenz ex Griseb. known as "palo santo" is one of the most important trees within the field of aromatic species. From its wood, an essential oil known as "guayacol" is extracted, with great international demand. In the country, studies about the chemical characteristics of the essential oil are very few. The objective of the present study was to characterize the chemical composition of the essential oil contained in the wood. Trunk sections of healthy individuals at 1.30 m were used. The extraction of essential oil was carried out by steam distillation equipment at atmospheric pressure. The essential oil was analyzed using a gas chromatograph coupled to a mass spectrometry (GCMS). The results indicate the presence of three main components: bulnesol (58.18%), guaiol (28.71 %) and elemol (10.17 %). In smaller percentages, the presence of α-gurjunene, α-guaiene and β-caryophyllene was detected. A more precise knowledge of the composition of the essential oil is required for a better understanding of potential benefits of B. sarmientoi
