General description

Silymarin is a flavonolignan, obtained from milk thistle (Silybum marianum) plant.

Application

Silymarin has been used to study:
  • its in vitro antiviral, antibacterial, antifungal activities and cytotoxicity
  • its effect of silymarin on bladder contractions in cyclophosphamide (CYP)-induced cystitis rat model
  • its effect on liver toxication induced by Fumonisin B1 in mice

Biochem/physiol Actions

Silymarin is originally known to protect liver from various toxic agents and is used in treating hepatitis and cirrhosis. Silymarin possesses many biological actions such as antifibrotic, anti-lipid peroxidative, anti-inflammatory, immunomodulatory and membrane stabilizing. Silymarin also aids in liver regeneration.
Silymarin provides cardioprotective activity against ischemia-reperfusion induced myocardial infarction in rats.
Silymarin was shown to protect the liver from the cytotoxic effects of anti-tuberculosis drugs by decreasing serum alanine aminotransferase (ALT), aspartate aminotransferase (AST) and alkaline phosphatase (ALP) levels. This effect was related to the anti-oxidant effects of silymarin.

Other Notes

Mixture of anti-hepatotoxic flavonolignans from the fruit of Silybum marianum.
