Chemical Composition and Antibacterial Activity of Essential Oil from (Rosmarinus Officinalis) and (Mentha Spicata) against Oral Pathogens

Article excerpt

Background: The microorganisms evaluated in this study are considered risk factors for oral diseases such as caries and periodontitis; they can also reach the bloodstream triggering other diseases in the human body, like endocarditis, brain abscesses, throat infections, respiratory and gastrointestinal system infections and bacteremia. Thus, this study carried out for antibacterial activity of essential oil from R. officinalis and M. spicata against some oral pathogens; Streptococcus mutans and Streptococcus sobrinus.

Methods: The chemical composition of the essential oils from leaves R. officinalis and M. spicata was determined by gas chromatography (GC) and gas chromatography-mass spec- trometry (GC-MS). Antibacterial activity of the essential oils of plants were determined in triplicate by using the microdi- lution broth method in 96-well.

Results: Carvon, Limonene and Menthone in leaf of M. spi- cata and 1, 8- cineol and alpha-pinene in leaf R. …
