Complementación del análisis químico y enantiomérico de la Fracción Volátil Destilada desde la Especie Ecuatoriana Piper subscutatum (Miq.) C. DC. (Piperaceae)

Abstract

Abstract: In the present research work, a chemical analysis was carried out complementing a previous study of the volatile fraction distilled from leaves of the Piper subscutatum species, collected in Numbani, Zamora Chinchipe, Ecuador. The analysis consists on hydrodistillation and the use of gas chromatography with polar and apolar, columns. We found 42 common compounds between both studies. Most of them were hydrocarbon sesquiterpenes (55.65%), oxygenated sesquiterpenes (8.55%) and hydrocarbon monoterpenes (8.25%), and in a smaller proportion, oxygenated monoterpenes ( 1.25%) and others (2.5%). We also made a standard deviation for each compound and a qualitative-quantitative chemical profile of the essential oil. Helped by a bibliographic review on species of the same gender, we determined possible applications of the essential oil studied, and that sesquiterpene E-caryophyllene, β- chamigreno and E-nerolidol were the most abundant compound which hasp harmacological applications. Other present compounds were the monoterpenes: α-pinene, β-pinene and terpinolene, and the sesquiterpenes: β-selinene and α-humulene with proven pesticidal and repellent activities. We concluded that Piper subscutatum has a great potential in two chemical areas of great importance: Pharmaceutical and Agrochemical.
