Chemical composition and antimicrobial activity of the essential oils of Senecio rufinervis DC. (Asteraceae)

摘要

The chemical composition of the essential oil obtained from the leaves and roots of Senecio rufinervis DC. was analyzed by GC, GC/MS and NMR. Germacrene D was the major constituent in both the oils studied (40.19 and 24.95%, respectively). The antimicrobial activity of the oil was determined by disc diffusion method. Results showed that both the oils exhibited significant antibacterial activity.
