Abstract

Africa is home to the tropical fruit plant known as Thespian garckeana. Its seeds are thrown, but its edible fruit is used as food or as herbal remedy. One kilogram of the powdered material was utilized, and a Soxhlet extraction method was performed to obtain the plant material's methanol crude extract. Alkaloid was not detected in the methanol extract of T. garckeana, despite screening for the presence of secondary metabolites in varied amounts. Folin-Ciocalteu, Aluminum Chloride colorimetric tests, and Folin's Phenol reagent were used to determine the total phenolics, total flavonoids, and total tannin content (TPC, TFC, and TTC). For total phenolics, total flavonoids, and total tannins, the internal standards were gallic acid, quercetin, and tannic acid. TPC was found at the highest concentration in the methanol extract of T. garckeana (54.00 ± 0.02 (mgGAE/g)), followed by TTC (24.67 ± 0.01 (mgTAE/g)) and TFC (11.99 ± 0.01 (mgQE/g)) in the quantitative study.The fruit (T. garckeana) demonstrated good antioxidant activity because the percentage inhibition increased as the concentration increased. The results of the three antioxidant models were reported as follows: (78.50 ± 0.01) for DPPH scavenging activity, (100.56 ± 0.03) for total antioxidant capacity, and (82.68 ± 0.01) for nitric oxide. The Gas Chromatography-Mass Spectrometry (GC-MS) was done and fifteen peaks were detected from the GC-MS spectra, corresponding to fifteen bioactive chemicals and the majority of the chemicals that were found were esters and carboxylic acids. According to this study, T. garckeana fruit possesses a substantial abundance of phenolic compounds and strong antioxidant properties in vitro. The fruit may potentially be used as a source of traditional medicine because the bioactive chemicals have key biological properties.
