Quercetin, the polyphenolic compound, which has the highest daily intake, is well known for its protective effects against aging diseases and has received a lot of attention for this reason. Both quercetin 3-O-β-d-glucuronide and quercetin 3′-O-β-d-glucuronide are human metabolites, which, together with their regioisomers, are required for biological as well as physical chemistry studies. We present here a novel synthetic route based on the sequential and selective protections of the hydroxyl functions of quercetin allowing selective glycosylation, followed by TEMPO-mediated oxidation to the glucuronide. This methodology enabled us to synthesize the five O-β-d-glucosides and four O-β-d-glucuronides of quercetin, including the major human metabolite, quercetin 3-O-β-d-glucuronide.
NEW SYNERGISTIC PHYTOCHEMICAL COMPOSITION FOR THE TREATMENT OF OBESITY

Synergistic anti-adipogenic and pro-lipolytic compositions for the prevention and amelioration of adipogenesis and lipolysis mediated diseases, comprising at least two extracts selected from enriched demethylated curcuminoids obtained from Curcuma longa, Moringa oleifera and Murraya koenigii. The anti-adipogenic and pro-lipolytic compositions optionally contain one or more anti-obesic agents. These compositions are useful for preventing anti-inflammatory and free radical mediated diseases.
