Abstract

The phenolic and antioxidant constituents in Acacia nilotica fruits have become an important source of medicinal and therapeutic benefit with powerful biological properties. This study investigated the phenolic content and antioxidant capacity of powdered Acacia fruits with seeds and without seeds. The phenolic content and antioxidant capacities in them were determined using Folin–Ciocalteu and DPPH free radical-scavenging assays. The total phenolic and antioxidants of A. nilotica with seeds were spectrophotometrically determined to be 47.61 and 6.18% greater than when the seeds were removed from the dried fruits, respectively. The LC–MS/QTOF analysis shows the presence of 282 and 214 phenolic compounds in the methanol extracts of A. nilotica with seeds and without seeds, respectively. The present study, therefore, revealed that dried A. nilotica fruits with seeds have higher total phenolic content, antioxidant capacity, and bioactive constituents, which indicated that they have more medicinal value than fruits without seeds.
