Popis: The goal of this study was to point out the effect of parameters (solvent, solid to solvent ratio and extraction time) on the extraction of condensed tannins from Rosa canina feedstock, using conventional methods such as room temperature extraction (RTE) and heat reflux extraction (HRE). Moreover, the extraction kinetics behaviour for HRE has been extensively studied in order to foreshadow a scale up process. The second order rate model was applied to estimate the extraction kinetics of a conventional heat reflux extraction (HRE) at different solid to liquid ratios, concentrations of solvent extraction times. Results showed that the second order rate model was the rate-governing step of the extraction process, and the predicted and experimental data fits very well.
