Chemical composition and antibacterial activity of Cochlospermum planchoni Hook.f. ex Planch essential oil from Burkina Faso

Abstract

The water distilled oil obtained from rhizomes of Cochlospermum planchonii Hook.f.ex Planch (Apocynaceae) from Burkina Faso was examined by GC and GC/MS. Cochlospermum planchonii oil presents a particular chemical composition with a high rate of oxygenated components with predominance of ketones and esters (86.4%). The essential oil was tested against twelve strains of bacteria using a broth microdilution method. The results suggest that Cochlospermum planchonii essential oil has significant bactericidal activity. © 2007 Asian Network for Scientific Information.
