Espectroscopia no infravermelho na análise da composição química de diferentes genótipos de Trifolium repens.
Abstract: White clover, Trifolium repens L., is a perennial legume with large forage importance. In the Embrapa Southern Livestock four genotypes has been studied (CPPSUL, Entrevero, Sintético 1 and Sintético 2) which none chemical characterization has been done. For another point of view, the infrared spectroscopy is a quickly, low cost method for identification of chemical compounds. Thereby, this work was made valuation of spectroscopy application and analyses composition of silica, condensates tannins and cellulose. Four genotypes were dry, 20 samples of which one were analyze separately on infrared spectrometer (Spectrum Perkin Elmer) and the graphical examined OriginLab software. The samples showed different intensity, therefore distinct compositions. The silica composition of Entrevero, Sintético 1 e Sintético 2 cooperating to CPPSUL was respectively 1.16, 1.14 e 1.37, for cellulose was 1.51, 1.08 e 2.07, and for condensates tannins 1.58 e 0.96 e 2.45. The infrared spectroscopy demonstrate like interesting analytical instrument for identification chemical composition being quickly, reproducible, without preparation and does not destroy the samples.
