Description
Silychristin is a flavonolignan isolated from Silybum marianum and has been shown to exhibit inhibitory activities against lipoxygenase and prostaglandin synthetase. It has a role as a radical scavenger, a lipoxygenase inhibitor, a prostaglandin antagonist and a metabolite. It is a flavonolignan, a member of 1-benzofurans, a polyphenol, an aromatic ether and a secondary alpha-hydroxy ketone.
Silicristin has been reported in Silybum eburneum, Anastatica hierochuntica, and other organisms with data available.
