Antibacterial Activity and Bioactive Compounds of the Adoyo Beverage

Adoyo beverage is an herbal drink consumed in Nigeria that offers medicinal benefits. This study aimed to assess antibacterial activity and bioactive compounds of the adoyo beverage. The antibacterial potential, antioxidant, flavonoid, vitamin C content, and chemical composition of the adoyo beverage were evaluated. The adoyo beverage was inhibitory against the test pathogen with a zone of 1.4 to 9.5 mm. It had total antioxidant, total flavonoid, and vitamin C content of 84.18%, 56.77 mg/mL, and 42.01 mg/mL, respectively. The chemical compounds were elucidated by gas chromatography– mass spectrometry (GC-MS) and yielded 21 peaks. The highest occurring compound was quinolinecarboxylic acid, while the lowest was benzisothiazole. Adoyo beverage had appreciable antibacterial activity and several bioactive compounds, hence can serve as a medicinal beverage.
