Flavonol glycosides in the petal of Rosa species as chemotaxonomic markers

Thirteen flavonol glycosides isolated from the petals of Rosa species in section Gallicanae, along with two flavonol glycosides isolated from Rosa rugosa, were quantitatively analyzed in petal extracts of 31 Rosa species. The content and classification by type of sugar moiety of flavonol glycosides were found to be important tools for classification of Rosa species, and two compounds were particularly useful as chemotaxonomic markers for section Cinnamomeae.107
