Determinação de concentração de princípios ativos em cinnamomum verum utilizando imagens hiperespectrais

Abstract

This work deals with the determination of concentration of active compounds in Cinnamomum verum. The goal of this work is to determine the concentration of the active compounds Gallic acid, Catechin and Resveratrol, in samples of Cinnamomum verum, using hyperspectral images. The determination of the concentration of the active compounds is performed by the methods of Partial Least Squares and Discriminant Analysis (PLS-DA). Three PLS-DA models were created for the active principles Gallic acid, Catechin and Resveratrol, the models obtained accuracy of 95.40%, 90.79% and 86.72%, respectively. Through the results obtained it is possible to confirm that the determination of the concentration of active compounds can be performed using hyperspectral images.
