Flavonol glycosides from flowers of Crocus speciosus and C. antalyensis.
From the flower extracts of Crocus speciosus and C. antalyensis nine flavonol glycosides have been isolated. One of these products is a new flavonol glycoside identified as kaempferol 3-O-alpha-(2,3-di-O-beta-D-glucopyranosyl)rhamnopyranoside by UV, mass and NMR spectroscopy.
