Perfilado Metabólico De Especímenes De Falso Pimiento (Schinus Molle) Introducidos En La Ciudad De Bogotá

Abstract

Schinus molle samples were collected at different locations in the city. They were studied on the one hand, fixed secondary metabolites and, on the other hand, volatile secondary metabolites. In the first case he made a cryogenic maceration and ultrasound assisted extraction in ethanol. The ethanolic extract obtained, the content of phenolic compounds was determined quantitatively through the Folin-Ciocalteu method and flavonoid content with AlCl3, in which a low Pearson correlation (CPC 0.08) was observed. chromatographic analysis by liquid chromatography coupled to high efficiency mass spectrometry in which compounds were identified tentatively 9, which is a compound meeting with important gender chemotaxonomic Schinus value, which is the Schinol was performed. In the second case is carried out supercritical fluid extraction and chromatographic analysis by gas chromatography mass spectrometry where 24 representative peaks, 17 of which were detected was performed were identified tentatively where 9 are the major compounds in the essential oil from the leaves of S. molle. Finally I was discriminated by OPLS-DA the presence or absence of flower and fruit, harvest time and geographical distribution identifying differences and similarities, and an analysis supervised quantitative data content of phenols and flavonoids, as well as the percentage and reaction yield identifying active compounds that explain the chemical variability of the plant. In conclusion it was evident, even though the plant is distributed in different environments and exposed to biotic and abiotic factors, presents a rich metabolome information given to studies that have been conducted in the species.
