Key Word Index-Vinca major; Apocynaceae; leaves; flavonol glycosides; kaempferol 3-O-(6''-O-rhamnosyl)-galactosides 7-O-glucoside; chlorogenic acid; mass spectrometry.Chlorogenic acid, robinin and flavonol triglycoside were isolated from the leaves of Vinca major.The structure of the triglycoside was determined to be kaempferol 3-O-(6''-rhamnopyranosyl)-galactopyranoside 7-O-glucopyranoside by fast atom bombardment, electron impact and negative ion desorption chemical ionization mass spectropetry.
