“…They also bind to adhesins, complex with cell wall and inactivate proteolytic macerating enzymes used by plant pathogens (Mohanta et al, 2007;Gurjar et al, 2012). From this it can be presumed that phenolic compounds act at two different points (cell membrane and cell wall), affecting the growth and metabolism of bacteria (Taguri et al, 2006;Stefanovic et al, 2012). Similar results have also been reported in other studies (Rajeshwar et al, 2005;Kuete et al, 2007).…”

“…There was bacteria growth on the surface or behind the film. Melissa, are known for presenting antibacterial activity against this bacterium [48]. Thereby, in this case, this extract resulted effective embedded in the polyurethane-urea nanoparticles (in-situ method) where the extract activity is protected and favored [49], as well as free among nanoparticles in the film (post-method).…”

A B S T R A C TPolyurethane-ureas are a versatile family of polymers which can be employed in a wide range of applications. Among them, waterborne polyurethane-urea (WBPUU) dispersions are gaining relevance in the field of environmentally-friendly products since their productive process adopts green synthesis routes, avoiding the use of organic solvents. Furthermore, their waterborne character can be exploited to incorporate several water compatible ingredients able to confer functional properties to the final materials. Among them, plant extracts, which are known to have relevant bioactivities, can be viewed as interesting candidates. Therefore, in this work, two extracts known to present antimicrobial activity (Melissa officinalis L. and Salvia officinalis L.) were obtained by the infusion method and incorporated into the WBPUU (1, 3 and 5 wt%) following different incorporation routes comprising its adding during different phases of the productive process (post-, in-situ and pre-methods). Thereafter films were prepared by solvent-casting and characterized from the viewpoint of physicochemical, thermal, mechanical, thermomechanical and antibacterial properties and morphologically. The studied incorporation routes resulted in different intercalation mechanisms that varied from extract positioned among the polyurethane-urea nanoparticles (post-method) to extract partially embedded inside them (in-situ and premethods), which produced stiffening or flexibilizing effects in the produced films, enhancing in general the antimicrobial characteristics of films after 4 days of incubation comparing with base WBPUU, especially when the extract is embedded.

Nature has been a source of medicinal agents since times immemorial.The importance of herbs in the management of human ailments cannot be over emphasized. Different extracts from traditional medicinal plants have been tested to identify the source of the therapeutic effects. needs to be purified through antibacterial activity guided fractionation to isolate and identify the compounds responsible for the antibacterial activity. So, this study provides the platform to carry out further researches to give light upon specific compounds which are responsible for their antibacterial activities.
