| Summary: | Plant extracts especially medicinal plants used as alternative treatment due to minimal side effect and danger to human health. The present study focuses on the phytochemical analysis and antimicrobial properties of medicinally recognized known plant of Catharanthus roseus.In this research, the bioactive secondary metabolites and antimicrobial activities of organic extracts of C. roseus flowers parts were investigated.The phytochemical screening of both ethanol and ethyl acetate plant extracts revealed the presence of various secondary metabolites such as alkaloids, flavonoids, protein, phenol, saponins and other phytochemicals.However, agar well diffusion method was used for antimicrobial testing of organic extracts against multidrug resistant (MDR) food-borne Gram-positive (Staphylococcus hominis) and Gram-negative (Citrobacter freundii, Escherichia coliand Aeromonascaviae) bacteria. The study revealed that the flower extracts of C. roseus showed highest (15.5± 0.50 mm) antibacterial activity againstCitrobacter freundii BTGE-K_4but the lowest (5.67± 0.58 mm) antibacterial activity against S hominisBTGE-K_11. Moreover, the lowest minimum inhibitory concentration (MIC) value was 125μg/mL which showed against the tested MDR bacteria.Moreover, this study supports the importance of using medicinal plants as an alternative source for the treatment of bacterial diseases and other pharmaceutical purposes such as preservatives due to minor side effects, cost effectiveness and development of resistance to antibiotics. |
