The purpose of this project was to evaluate the antibacterial potential phytochemicals rutin, syringic acid, and Ziziphus mucronata extract on Chromobacterium violaceum quorum sensing. Z. extracts were imported from South Africa, then extracted in lab; a SEM imaging series conducted for contamination further develop portfolio it. null hypothesis if plant compounds are tested individually, they ...

This study investigated the effects of some plant extracts on the bacterial communication system, expressed as quorum sensing (QS) activity. Quorum sensing has a directly proportional effect on the amount of certain compounds, such as pigments, produced by the bacteria. Alcohol extracts of 23 ornamental and medicinal plants were tested for anti-QS activity by the Chromobacterium violaceum assay...

A methanol-soluble extract of the bark of Myristica cinnamomea was found to exhibit anti-quorum sensing activity, and subsequent bioassay-guided isolation led to the identification of the active compound malabaricone C (1). Compound 1 inhibited violacein production by Chromobacterium violaceum CV026 when grown in the presence of a cognate signaling molecule, N-3-oxohexanoyl-homoserine lactone. ...
