Abstract
The present study is focused to assess the efficiency of avocado fruit peel waste in different in vitro activities in order to explore the possibility of utilizing waste as a value-added product in various applications. Preliminary phytochemical screening confirmed the presence of alkaloids, flavonoids, phenols, tannins, glycosides, and absence of sterols, saponins, resins, and thiols. Remarkable free radicals scavenging ability was observed in all the tested radicals namely, DPPH.(IC50 = 71.96 ± 0.44 μg/ml), nitric oxide (NO.) (IC50 = 149.46 μg/ml), hydroxyl (.OH) (107.91 ± 3.59 μg/ml), Superoxide (O2.−) (IC50 = 103.05 ± 2.19 μg/ml). In the antibacterial assay, the zone of inhibition was recorded as 9.5 ± 0.5, 12.0 ± 1.21, 7.5 ± 0.35, 6.0 ± 0.5 and 10.0 ± 1.0 for the strains of Escherichia coli, Klebsiella pneumonia, Pseudomonas spp., Staphylococcus aureus, and Bacillus spp. respectively. The Fourier Transform Infrared (FTIR) profiling indicated the existence of resilient functional groups and the gas chromatography–mass spectrometry (GC–MS) profiling was exhibited the presence of eighteen major components highly accountable for its pharmaceutical activities.
