Étude d'une méthodologie de prédiction de la caractérisation chimique de plantes tropicales riches en tanins condensés par chimiométrie

Abstract : Plant Condensed tannins may have multiple biological effects in farmed small ruminants in terms of food, health and environment. These effects vary according to the type and quantity of tannins. In order to incorporate condensed tannins into the diet of ruminants, it is necessary to be able to analyze them simply and quickly. However, current methodologies remain complex and difficult to implement. In this study, we evaluated the chemometric method of near infrared spectroscopy, as an alternative to conventional assays, for a rapid qualitative and quantitative analysis of condensed tannins of 3 tropical plants. Using SNV and SG1 spectral pretreatments and PLS regression, we have thus been able to develop a quantitative method applicable to Cassava and Pigeon Pea plants, with a calibration curve correlation and SECV of respectively 0,64 and 3,16 for Cassava, and of 0,87 et 2,95 for Pigeon Pea. Work is still to be done to reach a qualitative analysis for these plants.
