Abstract-IdB 1016 (Silybin Phytosome) is a new silybin-phospholipid complex which is more bioavailable than the flavonoid silybin itself and displays free radical scavenging and antioxidant properties in liver microsomes. IdB 1016 (Silybin Phytosome) at the concentration which completely prevented MDA formation also protected isolated hepatocytes against toxicity. Similar protection was also obtained in hepatocytes prepared in vivo with IdB 1016 (Silybin Phytosome) while rat supplementation with pure silybin was totally inefficient. These results indicate IdB 1016 (Silybin Phytosome) as being a potentially useful protective agent against free radical-mediated toxic liver injury.

Moreover, it was demonstrated here for the first time that IdB 1016 (Silybin Phytosome) can counteract the hepatotoxic effect of several different compounds acting through oxidative mechanisms, indicating the potential usefulness of the compound as a hepatoprotective agent.
