Several diterpene glycosides (e.g., rubusoside, rebaudioside, steviol monoside and stevioside) were discovered to enhance the solubility of a number of pharmaceutically and medicinally important compounds, including but not limited to, paclitaxel, camptothecin, curcumin, tanshinone HA, capsaicin, cyclosporine, erythromycin, nystatin, itraconazole, and celecoxib. The use of the diterpene glycoside rubusoside increased solubility in all tested compounds. The diterpene glycosides are a naturally occurring class of water solubility-enhancing compounds that are non-toxic and that will be useful as new complexing agents or excipients in the pharmaceutical, agricultural (e.g., solubilizing pesticides), cosmetic and food industries. Aqueous solutions by using rubusoside to increase the solubility of otherwise insoluble drugs will have several new routes of administration. In addition, aqueous solutions of therapeutic compounds with rubusoside were shown to retain the known pharmacological activity of the compounds.

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.
