Studies on solubility of curcumin

Curcumin is practically water insoluble and have poor bioavailability. In order to improve its water solubility, solid dispersions of curcumin were prepared by both hot melt method and solvent evaporation method. In hot melt method, PEG-4000, PEG-6000 were chosen as carriers. The ratios of drug to carrier were 1:1, 1:4 and 1:8.

The solubility of caffeine decreases in the order of chloroform, dichloromethane, acetone, ethyl acetate, water, methanol, ethanol, and carbon tetrachloride. The solubility of caffeine in chloroform showed a higher value than those in the other solvents . Thus, chloroform is a better solvent to separate and purify caffeine from solutions.

Solubility: Importance, Measurements and Applications

The TV method is the most suitable method for determining the temperature dependent solubility line of a compound in a solvent. Upon heating a suspension of known composition, the temperature at which all crystals are dissolved marks a point on the solubility line. After a recrystallization step through cooling, the measurement can be repeated.
