摘要：Quercetin is a flavonoid widely distributed in nature. It is rich in foods including fruits, vegetables,leaves and grains. It has been used in medicine to control the capillary fragility and blood breeding. It showspharmacological activities like anti-oxidant, anti-cancer, anti-viral and anti- inflammatory activities etc. The presentstudy was intended for the optimization of extraction of Quercetin from pine apple peel and its various physicochemicalparameters have been studied. For the extraction of Quercetin the optimum results were observed for theeffect of different solvents, soaking time, different solvent percentages, effect of pH, different volumes of hexane withmethanol as solvent, extraction time with hexane were methanol, 1day, 80% (v/v), 7.0, 1:1 ratio and 1hr respectively.The highest Quercetin concentration for optimized condition was 37μg/ml. Methanol was found to be the best solventfor the extraction of Quercetin from pineapple peel by soxhlet extractor. It was carried out for 90 min and an optimumconcentration obtained at 50 min with a concentration of 50μg/ml .This Solvent extraction using soxhlet extractor wasconduct to verify the mathematical model proposed in this work. The final form of proposed models were E(t) =At2+Bt+C Where A,B&C are constants,Es=yield extract(μg/ml of quercetin) and t=extraction time(min). The finalform of proposed equation is E (t)= -0.018t2+1.591t with R2=0.894.
