Phytochemical and Antibacterial Properties of Ethanolic SeedudExtracts of Chrysophyllum albidum (African Star Apple)

摘要

ABSTRACTudPhytochemical and antibacterial properties of ethanolic extract of the seeds of African StarudApple (Chrysophyllum albidum) were investigated.The phytochemical resultrevealed the presenceudof saponins, carbohydrates, flavonoids, quinones, cardiac glycosides, fatty acids and terpenoids.udThe antibacterial activity was studied using agar well diffusion method at different concentrationsudagainst six pathogenic bacterial strains, three Gram-positive(Staphylococcus aureus, Micrococcusudvariansand Bacillus cereus) and three Gram-negative (Escherichia coli, Pseudomonas aeruginosaudand Proteus vulgaris). Significant inhibitory activities were exhibited by the ethanolic seed extractsudfor all test organisms except Bacillus cereus. Zone of inhibition of the crude ethanolic extract wasudcorrelated with that of a standard antibiotic Gentamicin, for antibacterial activity. The results indicateduda notable inhibition of the bacterial growth.udKeywords: Chrysophyllum albidum, Seed extract, Cotyledon, Phytochemicals, Antibacterial
