The neutral fraction of the petroleum-ether-soluble bark extract contains a homologous series of normal alkanes (C19 to C42), free β-sitosterol, behenyl and lignoceryl alcohols, esters of these three compounds with arachidic, behenic, and lignoceric acids, and a major fraction comprising a mixture of behenyl and lignoceryl ferulates. The triterpene lactones cyclograndisolide and epicyclograndisolide are minor components.
