General description
Isosilybin B is a flavonolignan and a bioactive component present in silymarin, isolated from Silybum marianum. It is commonly used in the treatment of cirrhosis, hepatitis and prevents the liver from being exposed to toxic substances.
Application
Isosilybin B may be used as an analytical reference standard for the quantification of the analyte in compound preparations of Silybum marianum and Silybum.miltiorrhiza using high-performance liquid chromatography with photo diode array detection and electrospray ionization-mass spectrometry.
Refer to the product′s Certificate of Analysis for more information on a suitable instrument technique. Contact Technical Service for further support.
Packaging
Bottomless glass bottle. Contents are inside inserted fused cone.
