Sorbitol is water soluble, but insoluble in most organic solvents (except hot ethanol).

Caffeine is soluble in non polar solvents such as chloroform or methy chloride.

So try a multistage partitioning between the two solvents. (multistage is more separation efficient than doing it in one go)

You can look up the solubility in other solvents in pubchem
