In vitro Evaluation of Curcumin and Quercetin in Combination on Oxidative Stress
Indian Journal of Pharmaceutical Education and Research
Abstract
Background: Flavonoids are the natural product belongs to an important class of plant secondary metabolites. They are polyphenolic compounds and known for decades as a potent natural antioxidant. Curcumin (flavonoid polyphenol) and quercetin (flavonol) both are popular natural antioxidants and contributes a major role as an individual in the treatment of oxidative stress. This research study is more focused in their combination effect against oxidative stress. Materials and Methods: In this present research, we focused on hydro-alcoholic maceration of Curcuma longa rhizomes and Morinda citrifolia fruits to extract the curcumin and quercetin respectively. Also, their role in oxidative stress was studied using in vitro techniques. Results: The percentage (%) yield of hydro-alcoholic extract attained from Curcuma longa rhizomes and Morinda citrifolia fruits were found to be 23.06% and 21.08% respectively. Conclusion: Additionally, through DPPH (2,2-diphenyl-l-picrylhydrazyl) and Lipid peroxidation (LPO) assay, it was observed that curcumin and quercetin in combination gives the highest antioxidant activity when compared with their individual response at same concentration.
