Enhanced methods have been discovered, using either sonication or homogenization followed by increased temperature and pressure, to solubilize compounds using diterpene glycosides and to produce a powder form of the compound-solubilizer complex than can be reconstituted in water. Without the diterpene glycoside, the compounds were insoluble or sparingly soluble in water, including some fat-insoluble vitamins. Water solutions of these compounds were made using a diterpene glycoside solubilizer, for example, rubusoside. The compound-solubilizer complex was then dehydrated to a stable powder that could then be reconstituted with water. A reconstituted drug-solubilizer complex (curcumin-rubusoside) was shown to be effective on reconstitution. In addition, the diterpene glycoside, rubusoside, was shown to be an inhibitor of permeability glycoprotein (P-gp), and will thus increase gastrointestinal absorption of certain drugs administered with rubusoside.
