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.

This silymarine.....is it isomer of Silybinin A and B
1 answer-
This product is a fairly crude extract from Milk Thistle consisting of a number of components. The minimum purity specification for this material is 30%. Within that fraction there is a mixture of isomers. The amount of each has not been quanitified, however the literature suggests that these are present in the plant at equimolar ratios.

How much purity is there in this product?
1 answer-
This product is at least 30% Silymarin. The impurities have not been fully characterized. However, other Milk Thistle flavonolignans are expected to be present. These include dehydrosilybin, desoxysilycristin, desoxysilydianin, silandrin, silybinome, silyhermin, and neosilyhermin. In addition, apigenin, silybonol, as well as myristic, palmitic, stearic, and oleic acids have also been reported.
