Description
Summary:The GC and GC/MS analysis of the essential oil samples obtained separately from whole aerial parts and the roots of resulted in the identification of a total of 40 compounds from the whole aerial parts and 45 compounds from the roots representing 89.7% and 82.9%, respectively, of the total essential oil composition. The essential oil from aerial parts is dominated by oxygenated sesquiterpenes (66.4%) with elemol (55.1%), germacrene D-4-ol (4.2%), linalool (3.5%) and phytol (3.4%) as the major constituents while the root essential oil is dominated by oxygenated monoterpenes (30.4%) with -myrtanol (16.3%), -myrtanol (11.6%), nopinone (7.8%), cadin-4-en-10-ol (4.7%), and -elemol (3.4%) as major constituents. The essential oil from whole aerial parts showed bactericidal effect at 250 µL/mL concentration (MBC) against and while the root essential oil exhibited bactericidal effect at 125 µL/mL against , and .
