Abstract
In the present work we studied the solubility of sterigmatocystin (ST) in different organic solvents and the stability of these solutions du ring cold and frozen storage. ST was more soluble in chloroform and in pyridine. In cold storage ST was more stable in chloroform after both 7 and 30 days. In pyridine, ST was stable on day 7 but not on day 30. In frozen storage, 90% recovery was achieved only in chloroform. We c onclude that chloroform is the most suitable organic solvent of those studied to solubilize and store standard solutions of ST.
