Phytochemical investigation of the ethyl acetate extract of the aerial parts of Elytropappus rhinocerotis (L.f.) Less. led to the isolation of a coumarin (1), four flavonoids (2e5), and four labdane diterpenes (6e9). The structural characterization of the isolated compounds was based on spectroscopic data. All compounds are reported for the first time from this species and from the genus Elytropappus Cass. The isolation of labdane diterpenes and methoxylated flavones is of taxonomical significance.
