Abstract

Thenutritionalcompositions,antioxidantcapacities,andphenoliccompoundsof Alternanthera sessilis red (ASR) and green (ASG) in water and ethanolic extracts were compared. Nutritional compositions were determined according to anAOAC method.Total phenolic content was evaluated by a colorimetric reduction using the Folin–Ciocalteu method. Highperformance liquid chromatography combined with diode array and electrospray ionization mass spectrometric detection was used to the study phenolic compounds.Antioxidant capacities were evaluated by five different methods.The results showed that ASR contained significantly (p < 0.05) higher protein, fat, carbohydrate and mineral contents compared to ASG. The ethanolic extracts of both ASR and ASG presented significantly greater antioxidantcapacitythanthewaterextractsat p<0.05.Thetotalphenoliccontentexhibitedapositive correlation with the antioxidant capacities, which could be one of the critical contributors to the antioxidant activity of ASR and ASG.
