C-glycosylated Flavonoids Analysis Service

Online Inquiry


Flavonoids are a kind of polyphenolic compounds in which their chemical structure containing two phenyl rings linked by a propane bridge resulting in the characteristic 15-carbon (C6–C3–C6) flavan skeleton. Flavonoids can be classified in different subtypes according to the degree of unsaturation and degree of oxidation of the 3-carbon skeleton. Many of these compounds are glycosylated, when glycosides are formed, the glycosidic linkage is normally located in positions 3 or 7 and the carbohydrate can be L-rhamnose, D-glucose, glucorhamnose, galactose or arabinose (Figure 1). After being glycoslated, flavonoids increase solubility in the aqueous cellular environment and protects the reactive hydroxyl groups from auto-oxidation, which allows the transport of flavonoids from the endoplasmic reticulum to various cellular compartments and their secretion to the plasma membrane and the cell wall. So far, more than 300 C-glycosylated flavonoids have been found, which have diverse biological functions including protection against ultraviolet radiation and phytopathogens, signaling during nodulation as well as the coloration of flowers as a visual signal that attracts pollinators. In addition, certain C-glycosylated flavonoids have pharmacological bioactivity and therefore is beneficial for treating human diseases like diabetes and cancer. Scientists at Creative Proteomics take advantage of highly quantitative methods with high-performance liquid chromatography (HPLC) for the determination of C-glycosylated flavonoids related metabolites levels in various samples. Furthermore, we provide reliable, rapid and cost-effective C-glycosylated flavonoids related service to speed up your research aims.
