Abstract A natural polyphenolic compound Quercetin was extracted from widely available and consumed plant Allium fistulosum which has shown promising chemo preventive and chemotherapeutic activities in cancer. In this study‚ quercetin is encapsulated and loaded onto PLGA (Poly lactic glycolic acid) microspheres using double emulsification methodology for improving its efficiency in cancer therapy. Quercetin is extracted and purified using chromatographic and nuclear magnetic resonance (NMR) techniques
