Eriocitrin Spec

Eriocitrin is a flavanone-7-O-glycoside between the flavanone eriodictyol and the disaccharide rutinose. It is a flavanone glycoside. It is found at higher levels in lemon than in all other species of citrus. The principal citrus flavanones are invariably combined with various sugars, especially disaccharides.

Eriocitrin (eriodictyol 7-O-β-rutinoside), a flavonoid glycoside, is the key flavonoid in lemon fruit (citrus limon). It is very elusive and is the most soluble of all flavonoids.


It is an ingredient derived from natural products, and it is contained in a juice of citrus fruits such as lemon and lime which have been already eaten in a large amount of several tens of milligrams per 100 ml.

Further, a peel and a squeezed residue are secondary products provided in squeezing a fruit juice. The extraction of an active ingredient by reusing these portions is industrially quite useful, and this is extremely profitable from the aspect of utilizing a waste. Still further, in the industry of the fruit juice, besides the peel and the like, waste liquors such as feeding water and washing water used in that treatment are provided in large amounts, and these can be utilized as eriocitrin solutions.

How it works?

Eriocitrin and its metabolites by intestinal bacteria (eriodictyol, 3,4-dihydroxyhydrocinnamic acid, and phloroglucinol) exhibited stronger antioxidative activity and had approximately the same activity as (-)-epigallocatechin gallate. It and its metabolites are powerful antioxidants
