Phenolic Compounds and Antioxidant Activity of Some Citruses

Abstract

Citrus fruits (Rutaceae) are important source of phenolic compounds and their glycosides. These compounds are phenolic acids for bioactive responsible for the antioxidant and many other biological activities. Five citrus extracts were analyzed for total phenolic content and antioxidant activity using spectrophotometric and molybdenum reduction methods. Total phenolic content ranged from 0.192 to 0.747 mg GAE/mL, with antioxidant IC50 values between 6.00 and 78.11 mg/mL.
