Antioxidant activity of the commercial Casearia sylvestris Swartz extract

Abstract

This research aimed to evaluate the total antioxidant capacity of commercial Casearia sylvestris extract. Two different methods (Folin-Ciocalteau and Fast Blue) were used to quantify the content of total phenolic compounds. The ABTS⁺, Beta Carotene/Linoleic Acid, Phosphomolybdenum Complex, DPPH^-, and FRAP assays were used to evaluate the total antioxidant activity. The HPLC technique was used to identify and quantify bioactive compounds in the plant extract. Total phenolic compound levels were quantified in both assays used, with the Fast Blue method being able to quantify higher levels of these substances (526.18 ± 41.35). Twelve bioactive compounds were identified and quantified by HPLC. The major phenolic compound found in C. sylvestris extract was caffeic acid. This research indicates that the commercial C. sylvestris extract has strong bioactive potential.
