Title: Essential oil composition and antibacteral activity of Vismia baccifera fruits collected from Mérida, Venezuela. Author: Rojas J, Buitrago A, Rojas L, Morales A, Lucena M, Baldovino S. Journal: Nat Prod Commun; 2011 May; 6(5):699-700. PubMed ID: 21615035. 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-l1,4-diene (36.6%), cis-cadin-1,4-diene (18.8%) and beta-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 (ATCC 25923), Enterococcus faecalis (ATCC 29212), Escherichia coli (ATCC 25992), Pseudomonas aeruginosa (ATCC 27853) and Klebsiella pneumoniae (ATCC 23357) with MIC values ranging from 9 to 37 microg/mL.[Abstract] [Full Text] [Related] [New Search]
