The quorum sensing inhibition (QSI) activities of ethanolic extracts of selected Philippine ethnobotanicals against Pseudomonas aeruginosa BIOTECH 1335 were evaluated in the study. Ethnobotanicals tested were Bidens pilosa L. (Anwad), Cestrum nocturnum L. (Dama de Noche), Sarcandra glabra (Thunb.) Nakai (Hag-ob), Oreocnide trinervis (Wedd.) Miq. (Lal-latan), Derris elliptica Benth. (Opay), Alstonia scholaris (L.) R. Br. (Palay), Ageratina adenophora (Spreng.) R. M. King & H. Rob (Panawel) and Ayapana triplinervis (Vahl) R. M. King & H. Rob (Pantallion).Ethanolic extracts were subjected to assays on the phenotypic expression of virulence factors for P. aeruginosa: pyocyanin production and swarming motility.The ethanolic extracts of O. trinervis, C. nocturnum and A. triplinervis showed presence of QSI in both virulence assays of P. aeruginosa; whereas the ethanolic extracts of S. glabra, D. elliptica, A. scholaris and A. adenophora showed presence of QSI only on the swarming motility but not in pyocyanin production. All ethanolic extracts of the ethnobotanicals showed great potential in the development of anti-quorum sensing drugs as new strategy to combat bacterial infections and inhibition of quorum sensing related virulence processes.

Key words: Quorum sensing inhibition, Virulence factors, Ethnobotanicals, Pseudomonas aeruginosa.
