Resumen
Moringa oleifera has been reported to possess a high number of bioactive compounds;
hence, several food supplements are commercially available based on it. This work aimed to analyze
the phytochemical composition and antioxidant activity of commercial food supplements. The
phenolic composition of methanolic extracts was determined by using high-performance liquid
chromatography with diode-array and electrospray ionization mass spectrometric detection (HPLCDAD-
ESI-MSn), and the antioxidant activity was assessed by ABTS + and DPPH assays. Thirty-three
compounds were identified, and all the main compounds were quantified, observing that the main
contribution to the phenolic profile was due to kaempferol and quercetin glucosides. The antioxidant
activity in both assays agreed with the phenolic content: the higher the phenolic levels, the higher the
antioxidant activity. The obtained results were compared with those previously published regarding
Moringa oleifera leaves to establish the potential benefits of food supplement consumption in the diet.
