“…Throughout the plant, cotton is characterized by the presence of gossypol storage pigment glands that contain terpenoid aldehydes (Rathore et al, 2012). Gossypol is a phenolic compound produced by pigment glands distributed throughout plant, but concentrated in seeds (Alexander et al, 2008;Kenar, 2006;Rogers et al, 2002;Romano and Scheffler, 2008) and roots (Scheffler, 2016). Cottonseed contains several toxic chemicals as secondary metabolites, including gossypol, cinnamic acids, flavonoids, terpenoids, alkaloids, cyanohydrins, quinones, saponins, unsaturated lactones, benzoxazinones, allyl sulfides, thiocyanates, and polyacetylenes (Ingham and Harborne, 1976;Stoessl et al, 1976).…”
