Estudio comparativo por GC-MS de metabolitos secundarios volátiles de dos quimiotipos de lippia origanoides H.B.K., obtenidos por diferentes técnicas de extracción Fabián Tunarosa Jairo Martínez Carlos Ruiz Elena Stashenko Ingeniería extractos quimiotipos aceite esencial Lippia origanoides Se analizaron extractos de hojas de dos quimiotipos de Lippia origanoides.,cultivados en el Complejo Agroindustrial de CENIVAM (UIS). Se utilizaron lastécnicas de extracción: hidrodestilación asistida por radiación de micro-ondas,extracción con solvente - destilación simultánea y extracción con fluidosupercrítico. Los metabolitos secundarios fueron separados por cromatografíacapilar con detección de masas. La identificación se llevó a cabo porcomparación de espectros de masas con bases de datos, patrones e índices deKovàts. Los compuestos mayoritarios en los extractos para el quimiotipo Ifueron: p-cimeno (13%), y 1,8-cineol (9%). Para el quimiotipo II: timol (56%), yp-cimeno (10%). 2007 artículo científico 0122-1701 https://www.redalyc.org/articulo.oa?id=84903393 es http://www.redalyc.org/revista.oa?id=849 Scientia Et Technica application/pdf Universidad Tecnológica de Pereira Scientia Et Technica (Colombia) Num.33 Vol.XIII
