GC/MS and GC/FID analysis and evaluation of antimicrobial performance of Aframomum sceptrum essential oils of Benin

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
