Comparison of the Chemical Composition and Antimicrobial Activity of Two Types of Cosmos (Cosmos bipinnatus Cav. and Bidens ferulifolia (Jacq.) Leaf Essential Oils Introduced in Bangladesh

Cosmos is an aromatic plant with Essential Oils (EOs) used in food, flavouring, and medicine. A comparative investigation of the chemical composition and antimicrobial activities of the leaf EOs of Cosmos bipinnatus Cav. (cultivated) and Bidens ferulifolia (Jacq.) (wild) from Bangladesh has been conducted, whereas the composition of wild EO is being studied for the first time. Both EOs were extracted using the hydro distillation method, and the chemical composition of both EOs was identified by Gas Chromatography–Mass Spectrometry (GC-MS). The antimicrobial activity of cultivated EO was tested against ten pathogenic bacteria and six pathogenic fungi using the disc diffusion method. Even at 2 g disc-1, cultivated EO was able to inhibit all of the test microorganisms from growing. The value of EO was evaluated for the minimum inhibitory concentration (MIC, 100-30.. View More»
