Abstract

This work has studied the chemical composition of essential oils of limb, leaf sheath and rhizome of Aframomum sceptrum (Oliv. & T. Hand.) K. Schum (Zingiberaceae) collected in southern Benin, by GC and GC / MS and were tested for their effectiveness against pathogenic microorganisms. The main compounds noted in the essential oils of Aframomum sceptrum also called Aframomum masuianum (Oliv & D. Hand) are: for limb: β-caryophyllene (33.4%), β-pinene (28.4%), α-humulene (10.6% ), α-pinene (3.3%) and caryophyllene oxide (3.0%), for leaf sheath β-pinene (42.4%) and α-pinene (5,7%) and concerning the rhizomes; the results showed the following: β-pinene (15.9%), α-terpineol (l5.2%), β-caryophyllene (13.9%) and α-humulene (6.4%). The microbiological tests showed that essential oils of three organs of A. sceptrum have no activities related to the microorganisms studied.
