A brown pigment structually similar to gossypol has been isolated from cottonseed pigment gland material, It was purified and crystallized as the acetic acid adduct and certain chemical and physical characteristics of this compound have been determined, Further work is needed to prove the structure of this compound but data from this study indicate the compound may be a more highly oxidized form of gossypol, A naphthoquinone or naphthydroquinone type structure has been indicated by the infrared spectra, The structure of this compound is proposed as 6, 6`-dihydroxy-5, 5`-diisopropyl-3, 3`-dimethyl-(2, 2`-binaphthalene)-1, 1`, 7, 7`-tetrone-g, g`-dicarboxaldehyde.
