INCLUSION COMPLEXES OF THE NATURAL PRODUCT GOSSYPOL - THE FORMATION OF DIFFERENT GOSSYPOL POLYMORPHS ON DECOMPOSITION OF CHANNEL-TYPE INCLUSION COMPLEXES

The existence of seven gossypol polymorphs has been established. Two o f them are obtained by direct crystallization from solution. The remai ning five polymorphs are the products of desolvation of channel type c omplexes (tubulates). Each isostructural group of the complexes on dec omposition gives one polymorph. Gossypol thus possesses specific pecul iarities in terms of the decomposition of its tubulates, and also the absence of thermotropic polymorphic transitions.
