What would be an effective solvent to use for the solvent purification of DHEA?

For a chemistry lab experiment, I need to purify DHEA from some over the counter tablets. The inert ingredients in the tablets are "dicalcium phosphate, cellulose, and vegetable acetoglycerides." I need a solvent that will selectively dissolve DHEA and leave everything else behind. The DHEA needs to be pure enough to put in an NMR machine.
