The result reveals that the presence of monoglycosides of quercetin is a general character of flavonoids in the Chinese rhododendrons; some taxa are characterized by presence or absence of certain glycosides; although myricetin, and gossypetin are generally rare in this genus, they are concentrated in some taxa, and therefore they are valuable in chemotaxonomy. The significance of quantitative and semi-quantitative assessment of chem-ical characters for chemotaxonomy of Rhododendron is also discussed. %K Rhododendron L %K Flavonoids %K Flavonol glycosides %K Chemotaxonomy %K Quantitative analysis
