Abstract The aerial parts of Madia sativa afforded, in addition to known compounds, two labdanederivatives whose structures were elucidated by spectroscopic methods. The absolute configuration was determined by chemical transformations. From the roots a new tremetone derivative was isolated. The constituents indicated close relationships of Madia to Hemizonia .
