Optimization of the extraction process for flavonoids from basil (Ocimum basilicum) using response surface methodology

Basil (Ocimum basilicum), an edible and medicinal plant with high nutritional value and therapeutic efficacy, was used as a potential source of total flavonoids in this study. Heat reflux extractions were performed using aqueous ethanol. The optimized extraction conditions of total flavonoids from O. basilicum were determined by Box-Behnken design with response surface methodology. Response surface plots showed that the optional...
