摘要：

Gossypol and its two 2:1 and 4:1 tetrabutylammonium salts were investigated by H-1 and C-13 NMR spectroscopy in CDCl3 solution. In this solution gossypol exists as a symmetrical aldehyde-aldehyde tautomer. In the case of the two 2:1 and 4:1 tetrabutylammonium salts of gossypol in chloroform the anhydrogossypol form was observed, instead of the ketol form which was determined in CD3CN solution.
