Evaluación de la capacidad antioxidante de los aceites esenciales y extractos de tres quimiotipos de Lippia origanoides, por los métodos TEAC y ORAC, y su efecto protector en una matriz portadora de vitamina f (aceite de seje)

Abstract

The present investigation consisted in determine the antiradical capacity of the essential oils (AE) and extracts from three chemotypes of Lippia origanoides species, cultivated and harvested in the area of planting CENIVAM, located on the main campus of the Universidad Industrial de Santander ( UIS), Bucaramanga by ORAC and TEAC methods in a microplate reader Turner Biosystems Inc., ModulusTM II Microplate Multimode Reader microplate poly (styrene) of 96 wells and equipped with modules of absorbance UV-Vis and fluorescence (Sunnyvale , CA, USA) and by monitoring the hexanal as product of oxidative degradation of linoleic acid present in seje oil, for which was used the solid phase microextraction head-space mode (HS-SPME ), and gas chromatography with detector of micro-capture's electron (μ-GC-ECD) for measuring the derivative obtained by derivation hydrazonic with pentafluórfenilhidracina hexanal (PFPH).
