Phyllanthus emblica is a traditional medicinal plant that is endowed with curative properties including anti-bacterial, anti-fungal, anti-viral, and analgesic properties. Bacteria make use of cell-cell signaling system known as quorum sensing (QS) and respond to their own population. In most gram-negative bacteria, the transcriptional regulators belonging to the Lux R protein play a crucial role in the QS mechanism by detecting the presence of signaling molecules known as N-acyl homoserine lactones (AHLs). In this present work, the anti-quorum sensing activity of Phyllanthus emblica was evaluated against Pseudomonas aeruginosa. Anti-quorum sensing efficacy of Phyllanthus emblica was estimated with reference to QS bio-monitoring strain Chromobacterium violaceum. The binding efficacy of the phytochemicals of Phyllanthus emblica against CviR protein from Chromobacterium violaceum and LasR protein from Phyllanthus emblica were studied.
