Abstract Chlorogenic acid, robinin and a flavonoltriglycoside were isolated from the leaves of Vincamajor . The structure of the triglycoside was determined to be kaempferol 3- O -(6″- O -rhamnopyranosyl)-galactopyranoside 7- O -glucopyranoside by fast atom bombardment, electron impact and negative ion desorption chemical ionization massspectrometry.
