Sara Amrouche, Ratiba Derriche, Saida Messaoudi & Naima Lahouazi
Extraction of polyphenols from Inula viscosa (L.) leaves has been studied using water as a green solvent. Optimization of the process was performed using response surface methodology (RSM) in order to investigate the effects of three operating parameters, temperature, solid to liquid ratio and stirring speed (ω) in the following ranges : (28-56 ° C), (2-58 g.L-1) and (60-341 rpm), respectively. The efficiency of extraction was assessed by measuring polyphenols, flavonoids, and anthocyanins contents as...
