Cyclopropenoic acids ofPavonia sepium seed oil

  • Published:

Abstract

The seed oil ofPavonia 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.
