Abstract: Quercetin flavonoid are family of herbal plant compounds shows various pharmacological activities. In the present study, quercetin extraction show best results in the fermentation process than compare to extraction process due to biotransformation process. The highest concentration of quercetin was found to be 8.8µg/ml from the extraction process, and the concentration was found to be 9.6µg/ml from the fermentation process. The Extracts of the fermented process are shown with the maximum specific growth rate and the maximum yield factor (Yx/s) of Bacillus cereus are 0.3541 hr-1 and 0.234µg/ml. The extracts of non fermentation process (extraction) are shown the modelling equation for the quercetin yield extract was Es = 0.0733(1 – e-0.2767t). The model allowed fit accordance with the experimental data by producing average absolute relative deviation about 9.53%.
