Spectroscopic characterization (Raman and infrared) of Aloe maculata from the north Argentina region

In this work we present the Fourier-transform infrared (FTIR) and Raman spectra of Aloe maculata ( A.maculata )(“ maculata” = with spots ) gel after elimination aloin fraction. The analyzed samples were harvested from two zones different heights in northern Argentina. From FTIR measurements it was possible to identify presence pectin gel, where an analysis degree esterification done on basis characteristic marker bands for aloe samples. effect storage time both also monitored revealing that undergoes a decrease upon all By way, determined A. collected high lands, higher pectins than those low lands. order better follow distribution spectral signals, performed mapping selected area. helped determine characteristics fibers gel. Furthermore, theoretical calculations carried out molecular model one important component, acemannan, aided assignment modes groups This investigation is assess influence harvesting place use commercialization products, since gives rise viscosity and, consequently, bioavailability.
