Antioxidant activity of leaves of calophyllum rubiginosum
Calophyllum species have been used in traditional medicine for their therapeutic values for many years. This use was explained by several previous studies where antimicrobial, antifungal, anti-HIV and anti-cancer and antioxidant compounds were isolated from several Calophyllum species. Approach: The...

Calophyllum species have been used in traditional medicine for their therapeutic values for many years. This use was explained by several previous studies where antimicrobial, antifungal, anti-HIV and anti-cancer and antioxidant compounds were isolated from several Calophyllum species. Approach: The leaves were extracted with n-hexane (hexane), dichloromethane (DCM) and methanol using soxhlet apparatus. Total phenolic contents of each extract were evaluated using Folin Ciocalteau Reagent (FRC) while Ferric Thiocyanate (FTC) and 2,2-Diphenyl-1-Picrylhydrazyl (DPPH) were used for lipid peroxidation and free radical scavenging activity respectively. Results: As the results, methanol extracts (5 mg mL-1) has higher phenolic contents of 66.2 µg mg-1 Gallic Acid Equivalent (GAE) compared to n-hexane and DCM extracts with phenolic content of 50.5 and 52.5 µg mg-1 GAE respectively.
