Abstract: Abstract: Kaempferol 3,7-O-\alpha -L-dirhamnoside (I) and quercetin 3,7-O-\alpha -L-dirhamnoside (II) were isolated from the leaves of Tilia argentea (Tiliaceae). The structure elucidation of the isolated compounds was performed by spectroscopic techniques (^1H-NMR, ^{13}C-NMR, HMBC, CHSHF, DEPT and High Resolution FAB-MS). These 2 flavonoids are determined to be the main flavonoids of the leaves and are recommended as indicators for the adulteration of linden inflorescence with leaves known to possess weak healing activity.
