Evaluación del aceite asencial extraído de dos especies de albahaca: comercial (Ocimum basilicum L) y silvestre (Ocimum campechianum Mill) aplicado a soporte de papel patrimonial. Aspectos químicos y microbiológicos

Abstract

This investigation has the purpose looking microbicide activity of essential oils obtained on two basil species: Ocimum basilicum L and Ocimum campechianum Mill, and its effects on heritage paper. For this, this developing work was divided in five stages: species recollection and taxonomic classification; extraction, control and physical properties of essential oils; characterization of essential oil components by GC-MS; microbicide activity evaluation of essential oils under heritage paper sample and determination of essential oils effects under heritage paper samples, which it was made in National Library of Colombia, Archive of Bogotá and the laboratory of Haerentia business. Obtained results shown essential oil of Ocimum basilicum L was fungicide activity with microorganisms of genus Sytachybotris, Fusarium and Penicillium. Essential oil of Ocimum campechianum Mill was fungistatic activity in the same evaluated microorganisms and this essential oil didn´t change physicochemical composition of paper as pH and color when it was subjected to accelerated aging.
