Isoquercitrin——Worldwide Usage and Dosage
Nov 10, 2017


The flavonoid isoquercitrin HPLC 98% (quercetin-3-O-β-d-glucopyranoside) is commonly found in medicinal herbs, fruits, vegetables and plant-derived foods and beverages. This article reviews the occurrence, preparation, bioavailability, pharmacokinetics, toxicology and biological activity of isoquercitrin and "enzymatically modified (α-glucosylated) isoquercitrin" (EMIQ).

Pure isoquercitrin can now be obtained on a large scale by enzymatic rutin hydrolysis with α-L-rhamnosidase. The Isoquercitrin benefits decide the Isoquercitrin usage. the isoquercitrin uses are as following:


1.Isoquercitrin Applied in Pharma Field

Isoquercitrin has higher bioavailability than quercetin and displays a number of chemoprotective effects both in vitro and in vivo, against oxidative stress, Isoquercitrin cancer, cardiovascular disorders, diabetes and allergic reactions. Although small amounts of intact isoquercitrin can be found in plasma and tissues after oral application, it is extensively metabolized in the intestine and the liver. Biotransformation of isoquercitrin includes deglycosylation, followed by formation of conjugated and methylated derivatives of quercetin or degradation to phenolic acids and carbon dioxide.


2.Isoquercitrin Applied in Health Food

The acceptable isoquercitrin dosage of daily intake of (95%) isoquercitrin and of EMIQ was estimated to be 5.4 and 4.9mg/kg/day, respectively. Adverse effects of higher doses in rats included mostly (benign) chromaturia; nevertheless some drug interactions may occur due to the modulation of the activity and/or expression of drug metabolizing/transporting systems. With respect to the safety, affordability and beneficial pharmacological activities, highly pure isoquercitrin is a prospective substance for food supplementation.


3.Isoquercitrin Applied in Agricultural Field

Toxic effects on larvae of cotton-fly bud Worms in the agricultural field.
