Hemigossypol-6-methyl ether, reported to be present in the root bark of Bombax malabaricum, has been shown to be isohemigossypol-l-methyl ether. Isohemigossypol-1,Zdimethyl ether, %formyl-7-hydroxy-5-isopropyl-2 methoxy3-methyl-l+naphthaquinone, 7-hydroxycadalene and an unidentified phenolic compound have also been isolated. Long range couplings in the 'H NMR spectrum of isohemigossypol-l-methyl ether have been established by decoupling experiments.
