Bioactivity
Silybin A is the major active constituent of silymarin, a standardized extract of the milk thistle seeds, containing a mixture of flavonolignans consisting of silibinin, isosilibinin, silicristin, silidianin and others. Silibinin itself is a mixture of two diastereomers, silybin A and silybin B, in approximately equimolar ratio. Both in vitro and animal research suggest that silibinin has hepatoprotective (antihepatotoxic) properties that protect liver cells against toxins. Silibinin has also demonstrated in vitro anti-cancer effects against human prostate adenocarcinoma cells, estrogen-dependent and -independent human breast carcinoma cells, human ectocervical carcinoma cells, human colon cancer cells, and both small and nonsmall human lung carcinoma cells.

Chemical Information

Silibinin

Silibinin is a flavonolignan isolated from milk thistle, Silybum marianum, that has been shown to exhibit antioxidant and antineoplastic activities. It has a role as an antioxidant, an antineoplastic agent, a hepatoprotective agent and a plant metabolite. It is a secondary alpha-hydroxy ketone, a polyphenol, an aromatic ether, a benzodioxine and a flavonolignan.
