Abstract:

The essential oil from the fruits of Vismia baccifera Triana & Planch. (Gutttiferae), collected in June 2009, was analyzed by GC/MS. A yield of 0.6% oil was obtained by hydrodistillation. Twenty-seven components were identified by comparison of their mass spectra with those in the Wiley GC-MS Library data base. The major components were trans-cadin-1,4-diene (36.6%), cis-cadin-1,4-diene (18.8%) and β-caryophyllene (11.9%). The essential oil showed a broad spectrum of antibacterial activity against the important human pathogenic Gram-positive and Gram-negative bacteria Staphylococcus aureus

Background: Dental caries is an oral disease generated by pathogenic bacteria, Enterococcus faecalis, which is most frequently found in teeth with pulp necrosis. On the other hand, the use of the medicinal plant to treat pathogenic disease, including caries is an alternative option, which consumes synthetic drug having a side effect. Objective: The purpose of this study is to isolate antibacterial agents from Buah Merah (Pandanus conoideus Lam) and to test the antibacterial activity of those compounds against Enterococcus faecalis ATCC 29212.
