AN ASSESSMENT OF THE RELATIVE ANTIOXIDANT ACTIVITY OF BARK EXTRACTS OF ACACIA CATECHU BY IN VITRO FREE RADICAL SCAVENGING ANALYSIS Original Article

International Journal of Pharmacy and Pharmaceutical Sciences, 2024

Objective: The objective of this research was to examine and compare the capacity of several bark extracts of Acacia catechu to scavenge nitric oxide (NO) free radicals. The study also examined the evaluation of variations in concentration that are reliant on both concentration levels and seasonal changes, using samples obtained throughout various seasons over a span of two consecutive years. Methods: In this study, six extracts were made utilizing solvents, including ethanol, methanol, aqueous solution, acetone, chloroform, and benzene. In the in vitro investigation, a nitric oxide (NO) assay was conducted to evaluate the free radical scavenging efficacy of the test samples. Results: Out of seven tested sample concentrations, 15.25 µg/ml was reported to be ineffective; higher than 500 µg/ml concentrations (i.e., 705 and 1000) were observed to be less effective than their lower concentrations, while 31.5-500 µg/ml drug concentrations were observed to be protective. Among these three, 125 µg/ml concentrations were found to be most effective (p<0.01 or more). In solvent-based results, methanolic, ethanolic, aqueous, and acetone extracts exhibited at least p<0.01 significant effective NO scavenging, but acetone extract was seen to have comparatively less protection (p<0.05) than the other three extracts. Chloroform and benzene extracts, respectively, showed less protection. Samples collected in the summer season showed greater protection than winter and Manson. Conclusion: This study provided a clear observation of the impact of extraction solvent, concentration of drug, and season of sample collection on in vitro free radical scavenging potential. These data could help provide possible applications for regional plants for medicinal purposes.

The aim of this research was to investigate the phytochemical composition and the antioxidant activity of the Acacia nilotica extracts. The samples (fruits and trunk bark of Acacia nilotica L.) were collected in Kayes (Mali). The phenolic compounds of the different plant extracts were assayed by spectrophotometry and identified by HPLC. The antioxidant efficacy of the extracts was evaluated by using 2, 2azinobis-3-ethylbenzothiaz oline-6-sulfonic acid (ABTS) and 2, 2-Diphenyl-1-Picrylhydrazyl (DPPH)radicals scavenging capacities. The obtained results revealed that all the extracts are rich on polyphenols, flavonoids, tannins and anthocyanins. The contents of total polyphenols varied from 147 to 215 mg EAG/100 g, of total flavonoids from 1123 to 3037 mg EC /100 g, of total tannins from 67 to 289 mg EC/100 g and of total anthocyanins from 57 to 144 mg ECG / 100g of dry matter (DM). The highest values of those compounds were recorded in fruit extracts with respectively 215 mg EGA, 3037 mg EC, 289 mg EC and 144 mg ECG/100g (MD).HPLC analysis of fruit extracts revealed the presence of a flavonoid, named rutin, and four phenolic compounds, gallic, protocatechuic, chlorogenic and caffeic acids, which are recognized as bioactive compounds. All of our studied extracts displayed highest ABTS and DPPH radical scavenging capacities. The values varied from 72 to 350 mg EVC/100g (DM). The antioxidant activities of extracts were significantly correlated to their high contents of total phenolic and total flavonoids compounds. These justify the medicinal properties of the plant.
