| Abstract: | The volatile oils of the aerial parts and roots from a pasture plant, Elionurus elegans, were studied by GC-MS analyses. Both organs studied contained only terpenic constituents. The main components found in the extract essential oils of the aerial parts were campherenone (43.0%), caryophyllene oxide (4.9%), and bisabolone (4.9%), whereas those found in the root essential oils were campherenone (39.0%), epi-beta-santalene (12.0%), and caryophyllene oxide (4.6%). Furthermore, the oils were tested for antibacterial and antifungal activities. The results obtained led to a nonsignificant inhibitory effect, although an increase of the lag stage was shown for the kinetics growth of Candida albicans, Saccharomyces cerevisiae, Enterococcus hirae, and Staphylococcus aureus. When alpha-tocopherol is used as a control, the antioxidant activities of the oils obtained from the aerial parts and roots were 30 and 46% IC(50), respectively. |
