Chemical composition and antimicrobial activity of the essential oils of leaves, roots and bark of Glossocalyx staudtii.
Nat Prod Commun. 2009 Aug; 4(8):1127-32.NP

Abstract

The chemical composition of the essential oils obtained by hydrodistillation from air dried leaves, bark and roots of Glossocalyx staudtii Engl. grown in Gabon was analyzed by GC and GC-MS. The essential oil content was 0.84% (w/w), 0.28% (w/w), and 0.74% (w/w), respectively. The leaf oil was characterized by a high content of monoterpene hydrocarbons (64.8%), with beta-pinene (30.6%) and alpha-pinene (22.6%) as the major constituents. The oil obtained from the bark contained 30.5% of oxygenated monoterpenes with cryptone as the main constituent (11.5%) and 28.9% of aliphatic compounds, with 9.3% of 2-tridecanone; in the roots oil, the main component was 2-tridecanone (55.2%). The antimicrobial activity of the oils was studied by means of the agar disc diffusion and broth microdilution methods. The Gram positive bacteria were the most sensitive to the essential oils. A significant anticandidal effect of the bark essential oil was observed.
