Kaempferol 3,7-O-alpha-L-dirhamnoside (1) and quercetin 3.7-O-alpha-L-dirhamnoside (H) were isolated from the leaves of Tilia argentea (Tiliaceae). The structure elucidation of the isolated compounds was performed by spectroscopic techniques (H-1-NMR, C-13-NMR, HMBC, CHSHF, DEPT and High Resolution FAB-MS). These 2 flavonoids are determined to be the main flavonoidss of the leaves and are recommended as indicators for the adulteration of linden inflorescence with leaves known to possess weak healing activity.
