O-glycosylated Flavonoids Analysis

Online Inquiry


O-glycosylated flavonoids are an important group of flavonoids. The common o-glycosylated flavonoids mainly include quercetin 3-O-β-D-glucuronide and quercetin 7-O-β-D-glucopyranoside. Quercetin 3-O-β-D-glucuronide can be derived from dried whole grasses of hedyotis diffusa willd, flowers of gossypiumherbaceum L, or the leaf of apocynum lanci-folium rus, which can also be prepared by chemical synthesis. Quercetin 3-O-β-D-glucuronide is soluble in DMSO, alkaline water, insoluble in fat-soluble organic solvents. It is a yellow acicular crystal in water, and soluble in alkaline solution shows deep yellow. Quercetin 7-O-β-D-glucopyranoside can be derived from sophora flavescens ait, generally soluble in DMSO, methanol and other solvents, but insoluble in petroleum ether. Because o-glycosylated flavonoids have a wide range of uses, it is very important to establish the method for the analysis of o-glycosylated flavonoids in plant metabolites. High performance liquid chromatography is a sensitive analytical technique that enables detection, identification and quantification of a variety of o-glycosylated flavonoids by characterizing their chemical structure, even at low abundance. Improved extraction and purification steps can also increase the sensitivity of the analytical method.
