Abstract:Este estudo avaliou a ação do extrato etanólico das folhas de Myrciaria cauliflora (Mart.)O.Berg. sobre três culturas de Streptococcus formadoras do biofilme dental. A atividade antimicrobiana foi determinada pelo método de difusão em meio sólido. Os dados obtidos foram satisfatórios para todas as espécies ensaiadas (Streptococcus mutans ATCC 25175, Streptococcus sobrinus ATCC 27609 e Streptococcus sanguis ATCC 10557) gerando halos de inibição quando utilizado o extrato puro e diluições 1:2 e 1:4.

“…The use of medicinal plants for the treatment of various diseases including bacterial and fungal infections is common in Brazil (Carvalho et al, 2009;Pereira et al, 2007;Schubert et al, 2007). Worldwide, many search groups that use plants detect secondary metabolites with antimicrobial properties in an attempt to find new antimycobacterial or antifungals compounds (Cos et al, 2006;Soberón et al, 2007;Rangasamy et al, 2007).…”
Azadirachta indica A. Juss, known as neem (Meliacea family), has insecticide and pesticide properties, and many studies have shown their efficacy as antifungal, anti -inflammatory, among others. Studies for the development of drugs from plants are rising due to several factors such as bacterial resistance, indiscriminate use and the adverse reactions of antibiotics. In this study, phytochemical triage and thin layer chromatography analysis were performed, with similar results as the presence of flavonoids, tannins and terpenes. The antimicrobial activity showed that the ethyl acetate extract and butanol fraction presented greater activity against Streptococcus mutans and Streptococcus mitis presenting a MIC = 50 µg/ml for these strains, and the strain Enteroccocus faecalis, the hydroethanolic extract and aqueous fraction were most promising samples with a MIC = 50 µg/ml and MIC = 25 µg/ml, respectively. Therefore, it encourages the continuation of studies, aiming at the devel opment of cosmetics or toothpaste.

“…(Myrtaceae) is a native plant from Brazil and can be found throughout the country [135]. Tests performed in vitro using the alcoholic extract of this plant's leaves against S. mutans demonstrated that this extract acts on biofilm formation and could be an alternative for use in toothpastes [136,137].…”
Section: Myrciaria Cauliflora (Mart) O Bergmentioning
“…Myrciaria Cauliflora pertencente à família Myrtaceae, desempenha ações antiinflamatória, antiviral, hipolipidêmica, contribui na redução de doenças cardiovasculares e também antimicrobiana frente a Lactobacillus casei e Streptococcus mutans (CARVALHO et al, 2009). O objetivo do estudo foi desenvolver formulações de bala fitoterápica à base de os extratos da casca do fruto de Punica granatum Linn (romã) e de folhas de Myrciaria cauliflora (jabuticabeira) e avaliá-las quanto à atividade antibacteriana frente as bactérias cariogênicas.…”
Avaliar a ação dos extratos hidroalcóolicos de cascas de Punica Granatum Linn (Romã) e das folhas de Myrciaria cauliflora (jabuticabeira) incorporados a uma bala mastigável, também desenvolvida no estudo, sobre três linhagens de bactérias formadoras do biofilme dental, Streptococcus Mutans, Streptococcus Sanguinis, e Lactobacillus casei. Métodos: Trata-se de um projeto experimental quantitativo, cujas atividades foram realizadas nos laboratórios de tecnologia de alimentos, microbiologia de alimentos,
