Abstract

An oral micro-emulsion composition comprising a Carduus marianus extract, silybin or a silybin derivative; an organic solvent; a surfactant; and an oil provides a high in vivo bioavailability of silybin.

Description

Invention field [0001] The present invention relates to an oral silybin composition with higher bioavailability of silybin, and more specifically to a microemulsion composition containing Carduus marianus extract or silybin. Background of the invention [0002] Silymarin is the main component of Carduus marianus extract, and it is known to have a very excellent protective effect on liver cells from smoking, drinking, overwork, environmental pollution, stress or liver damage drugs. However, due to the low solubility of silymarin in water, its oral administration bioavailability is very low. [0003] Korean Patent Application No. 96-13361 describes a method for increasing the solubility of silymarin, in which silymarin is dissolved in a mixture of polyethylene glycol and ethanol, and then the resulting solution is added to an aqueous polysorbate solution to prepare a silymarin solution. However, the disadvantage of this method is that the increase in solubility of silymarin is only...
