Obesity is one of the most important worldwide health problems. Previous studies have reported that consumption of flavonoids in the diet is inversely correlated

to lower morbidity and mortality from coronary heart disease and many studies have shown that quercetin might possess beneficial effects on lipid and glucose

metabolisms. These studies suggest that quercetin is promising as new pharmacologic agent for the treatment of obesity-related health problems such as

metabolic syndrome. Thus, we investigated the impact of quercetin glucosides(QG), which are enzymatically trans-glycosylated isoquercitrin from natural sources

and have improved bioavailability, on visceral fat mass in diet-induced obese mice and the obese human.

Introduction & Objection

This study suggested that the quercetin glucosides activate lipolytic pathway in adipose tissues and are beneficial to improve obesity in human.

【Summary of Exp.2】Quecetin accelerated the NEFA and glycerol release and phosphorylation of HSL in dose-dependent manner in 3T3-L1 adipocytes,

【Summary of Exp.3】In a clinical study, daily quercetin glucoside intake for 12w resulted in significant reduction of visceral fat mass in healthy obese people and they had experienced no adverse effects.

【Summary of Exp.1】 Supplementation of quercetin glucosides in diet-induced obese mice resulted in reduced body weight gain, and significant reduction of adipose tissue mass and hypertrophy.
