Goiânia: Sociedade Brasileira de Química, 2016. Resumo T00514-1.c2016  aShikimic acid is a natural compound, precursor of the antiviral Oseltamivir used against influenza A. It is a scarce and expensive chemical, obtained mainly from seeds of shrubs natives in China and Japan. In this study we propose a fast and clean procedure for the quantification of shikimic acid in B. plantaginea, an alternative source of shikimic acid, using NIR spectroscopy combined with PLS regression.  ashikimic acid  aBrachiaria Plantaginea  aChemometric analysis  aNIR spectroscopy  aPLS regression1 aMATALLO, M.
