ABSTRACT

The solubilities of 2-(3,4,5-trihydroxyphenyl)chromenylium-3,5,7-triol (delphinidin) in water, methanol, ethanol, and acetone have been measured spectrophotometrically at various temperatures ranging from (298 to 343) K under atmospheric pressure. Delphinidin is most soluble in methanol, followed by water, ethanol, and acetone at all measured temperatures. The experimental data were correlated using the modified Apelblat equation. The calculated solubilities for all solvents showed good agreement with the experimental data in the temperature range studied.
