composition and antimicrobial activity of stem bark essential oil of Goniothalamus cardiopetalus (BI.) Hook.f. et Thoms

A hydrodistilled oil obtained from the stem bark of Goniothalamus cardiopetalus (Annonaceae) was analyzed by GC/MS. The oil showed a total of 60 components of which 40 compounds representing 67.1% of the oil were identified. Linalool (11.7%), alpha-pinene (7.0%), trans-pinocarveol (5.2%), caryophyll...

Description
Summary:A hydrodistilled oil obtained from the stem bark of Goniothalamus cardiopetalus (Annonaceae) was analyzed by GC/MS. The oil showed a total of 60 components of which 40 compounds representing 67.1% of the oil were identified. Linalool (11.7%), alpha-pinene (7.0%), trans-pinocarveol (5.2%), caryophyllene oxide (5.0%) -terpineol (4.9%), guaiol (4.4%) camphor (3.9%) and bornyl acetate (3.9%) were found to be the major individual constituents of the oil. The antimicrobial activity of the oil was tested against a panel of 17 bacterial and six fungal strains by the disc diffusion method. The oil inhibited the growth of all test organisms at varying levels and the minimal inhibitory concentrations (MIC) were also determined.
