Silybin

CAS 22888-70-6: Silybin

Description:Silybin, also known as silibinin, is a flavonoid compound derived from the milk thistle plant (Silybum marianum). It is primarily recognized for its hepatoprotective properties, making it a popular supplement for liver health. Silybin exhibits antioxidant activity, which helps to neutralize free radicals and reduce oxidative stress in cells. The compound is known to enhance the activity of certain liver enzymes and promote the regeneration of liver tissue. Additionally, silybin has been studied for its potential anti-inflammatory and anticancer effects, as it may inhibit the growth of various cancer cell lines. It is typically available in the form of silymarin, a complex of flavonolignans that includes silybin as its major active component. Silybin has low solubility in water, which can affect its bioavailability; however, various formulations, including phospholipid complexes, have been developed to improve its absorption in the body. Overall, silybin is valued for its therapeutic potential, particularly in the context of liver disorders and overall health.
