Diosmetin

Diosmetin is a flavonoid compound that appears as a yellow powder. It is extracted from lemon and also found in various other natural plants, including spearmint and spider incense. Diosmetin is slightly soluble in methanol but readily dissolves in DMSO.

Diosmetin (Diosmin EP Impurity F) is a metabolite of Apigenin. It exhibits anticancer, antimicrobial, antioxidant, oestrogenic, and anti-inflamatory activities. Diosmetin can be used in the production of functional foods, cosmetics, and future drugs with antioxidant, anti-infective and anti-shock effects.

ChEBI: Diosmetin is a monomethoxyflavone that is the 4'-methyl ether derivative of luteolin. It is a natural product isolated from citrus fruits which exhibits a range of pharmacological activities. It has a role as an antioxidant, an antineoplastic agent, a plant metabolite, a tropomyosin-related kinase B receptor agonist, an apoptosis inducer, an angiogenesis inhibitor, a cardioprotective agent, a bone density conservation agent, an anti-inflammatory agent and a vasodilator agent. It is a monomethoxyflavone, a trihydroxyflavone and a 3'-hydroxyflavonoid. It is functionally related to a luteolin. It is a conjugate acid of a diosmetin-7-olate.
