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
