The seed oil of Pavonia sepium (Malvaceae) contains sterculic (7%) and malvalic (4%) acids. Countercurrent distribution in a hexane‐acetonitrile system concentrated and resolved the homologus cyclopropenoid methyl esters. Reductive ozonolysis of selected countercurrent distribution fractions gave β‐diketoesters, which were identified by gas chromatography‐mass spectrometry as derivatives of sterculic and malvalic acids. Pavonia sepium is the first known species in the plant family Malvaceae whose seed oil contains more sterculic than malvalic acid.
