Ginsenosides

as the major constituent of Ginseng Radix et Rhizoma

possess significant anti-tumor effect. However

ginsenosides exhibit poor clinical bioavailability due to thelow water solubility. This paper reviewed the development and researches on novel drug delivery systems for ginsenosides in recent years

including liposomes

nanoparticles

emulsions

microspheres

etc. These drug delivery systems could endow ginsenosides improved bioavailability as well as certain controlling release or targeting capability. In addition

micelles

fibrous membranes are also employed for ginsenosides delivery. To date

ginsenosides delivery systems are not deeply developed

the trend in the future is the combination of multi-functional systems. This review may provide certain guidance or instruction for developing novel anti-tumor drug delivery systems in the future.
