ABSTRACT
Two new and seven known compounds, including terpenoids and aromatic compounds, were isolated from the essential oil of Brazilian propolis. The structures of the new compounds were elucidated as 2,2-dimethyl-8-prenyl-6-vinylchromene (1) and 2,6-diprenyl-4-vinylphenol (2) on the basis of spectroscopic analyses.
