Comparative In vitro Antioxidant Properties of Dialium guineense Pulp and Seed

Abstract

Background: Plants rich in antioxidants are implicated in disease prevention, cellular protection, inflammation modulation, boosting immune function, supporting gut health, enhancing skin, and aiding wound healing. Objectives: The study was designed to investigate the comparative antioxidant properties of Dialium guineense pulp and seed. Methods: The extracts were assayed for scavenging activity against 1, 1-Diphenyl-2-picrylhydrazyl (DPPH), 2,2'-azino-bis- 3-ethyl benzthiazoline-6-sulphonic acid (ABTS), superoxide, hydrogen peroxide, hydroxyl radicals, and ferric reducing antioxidant property (FRAP) using standard laboratory methods. Results: The seed extract showed higher antioxidant potential scavenging DPPH free radical, ABTS free radical, superoxide radical and hydroxyl radical when compared to the pulp extract. Conversely, the pulp extract exhibited higher antioxidant potential scavenging hydrogen peroxide, as well as strong ferric reducing antioxidant property when compared to seed extract. Conclusion: Both the seed and pulp of Dialium guineense can be useful in combating diseases and cellular damage.
