Eriocitrin is a flavanone glycoside phytochemical found predominantly in lemons and certain citrus fruits. It contributes to the antioxidant flavonoid profile of citrus peel and juice tissues.
Eriocitrin functions mainly as a citrus polyphenol involved in oxidative stress modulation, endothelial signaling, inflammatory pathway interactions, and cellular redox regulation. Research has explored its effects on antioxidant enzyme systems, nitric oxide pathways, mitochondrial signaling, and inflammatory mediators.
Within citrus foods, eriocitrin exists alongside hesperidin, naringin, and additional flavonoids that collectively contribute to citrus phytochemistry.
Plants synthesize eriocitrin through flavonoid biosynthesis pathways involving flavanone formation and glycosylation reactions. Lemon peel and membrane tissues are especially rich in eriocitrin.
Environmental conditions, fruit maturity, processing, and storage influence concentrations. Citrus rind generally contains higher levels than juice.
After ingestion, eriocitrin undergoes hydrolysis, absorption, microbial metabolism, conjugation, and circulation through detoxification pathways.
Eriocitrin activity is regulated by intestinal hydrolysis, microbiome composition, food matrix interactions, hepatic metabolism, and oxidative environment. Citrus processing methods influence availability.
Research suggests eriocitrin may interact with oxidative stress pathways, endothelial signaling systems, inflammatory mediators, and vascular responses. Biological effects depend on concentration, metabolism, and tissue localization.
Consumption from lemons and citrus fruits provides eriocitrin together with vitamin C, carotenoids, hesperidin, and additional flavonoids that collectively contribute to antioxidant and vascular signaling diversity.
