A new labdane-type ditrpenoid acid, discoidic acid, has been isolated from the aerial parts of Grindelia discoidea.Its stucture has been deduced as 4β-hydroxymethyllabd-7-en-15-oic acid on the basis of the spectral data of its methyl ester derivative and comparison of these data with those of the methyl ester derivative of its isomer, 3-β-hydroxylabd-7-en-15-oic acid, also isolated from the same extract.In addition, a dihydroflavonol and two flavonols have been isolated.Key Word Index- Grindelia discoidea; Asteraceae; diterpenoid acids; labdanes; discoidic acid; flavonoids; mass spectrometry.
