Resumo

VOLATILE AND NON-VOLATILE CHEMICAL CONSTITUENTS OF Cochlospermum vitifolium (WILLDENOW) SPRENGEL.The essential oils from leaves, root bark and root wood of Cochlospermum vitifolium were investigated for the first time.The oils were obtained by hydrodistillation and analyzed by GC/MS.The main volatile constituents were β-caryophyllene (8.2 -46.5%), β-bisabolene (11.5 -29.3%), γ-muurolene (28.4%), α-humulene (26.0%), 1-hydroxy-3-hexadecanone (16.2 -19.5%) and β-pinene (10.6%).Phytochemical analysis of the root bark and root wood extracts yielded excelsin, pinoresinol, narigenin, aromadendrin, galic acid and a triacylbenzene, along with β-sitosterol and stigmasterol and their D-glucosides.The structures of all compounds were determined by analyses of the spectroscopic data (NMR and MS), and comparison with the literature.
