Biochem/physiol Actions

Morin hydrate is a flavonoid with antioxidant properties. It has been shown to protect cells against oxygen radical damage. Morin not only scavenges oxyradicals, but also moderately inhibits xanthine oxidase, a free-radical generating enzyme. At concentrations of 75-100 micromolar, morin inhibits oxidation of low density lipoprotein (LDL) by free radicals or Cu2+. Morin has been reported to inhibit rat brain phospha­tidyl­inositol­phos­phate kinase activity in vitro and in vivo.
