Antioxidant and Anti-malarial Properties of Catechins

Aims: This research was performed to evaluate the antioxidant and anti malarial activities of various catechins including catechin (C), epicatechin (EC), catechin-gallate (CG), gallocatechin-gallate (GCG), epigallocatechin (EGC), epicatechin-gallate (ECG), epigallocatechin gallate (EGCG).
Study Design: The antioxidant activity was measured by 1,1-diphenyl-2-picryl-hydrazyl (DPPH) scavenging activity and anti-malarial activity was determined by In vitro assay against P. falciparum culture, antioxidant activity was analyzed using linear regression analysis, and was continued by determining Inhibitory Concentration 50 (IC50). The anti-malarial activity was analyzed by probit analysis and IC50 determination.
Place and Duration of Study: Medical Research Center, Faculty of Medicine, Maranatha Christian University, Bandung. Pharmacognicy Laboratory, Airlangga University, Surabaya. Biomolecular and Biomedical Research Center, Aretha Medika Utama, Bandung, Indonesia from March 2013 to October 2013.
Results: The results showed that EC has the highest antioxidant activity with IC50 = 0.41μg/ml while ECG and GCG with IC50 = 0.52 μg/ml. For anti-malarial activity, CG has the highest anti malarial activity (IC50 = 0.37 μM).
Conclusion: Catechins have high antioxidant activity and CG has highest anti-malarial activity.
