Obtención y determinación de la composición química y enantiomérica del aceite esencial de Piper subscutatum de la provincia de Zamora Chinchipe

Abstract

Abstract:In the present investigation, the essential oil and floral water was analyzed, obtained from steam distillation, of leaves of Piper subscutatum (Piperaceae), The qualitative and quantitative analysis was carried out by the technique, (CG-EM) and to (CG-FID) with the use of chromatographic columns, HP-INNOWAX and DB-5M, it was possible to identify 66 essential oil compounds, of which the majority groups the hydrocarbon sesquiterpenes with 73.71%, oxygenated sesquiterpenes 10.29% followed by 8.41% hydrocarbon monoterpenes and the minority group of oxygenated monoterpenes with 1.4%, in turn the most representative compounds were; (E)-Caryophyllene 25.6%, β-Chamigrene 9.15%, (E) -Nerolidol 7.9%, β-Selinene 7.55%, while in the floral water analysis identified 13 compounds, with the ketones and oxygenated monoterpenes the majority groups with 84.25% and 13.75% respectively and those with the lowest proportion, the group of sesquiterpenes oxygenated with 3.21%, the main major components were Hepten-2-one 6-methyl-5 with 84.25% and Linalool with 8.62%. Finally, the enantiomeric analysis of the essential oil was carried out by CG-enantioselective, and the pairs of enantiomers corresponding to the components of α-Pinene, β-Pinene, Limonene and α-Copane were determined.
