TODO - A new compound kaempferol 3-O-α-L-(2''-E-p-coumaroyl)-rhamnopyranoside, as well as the known flavonoids, kaempferol 3-O-β-D-(6''-E-p-coumaroyl)-glucopyranoside, kaempferol 3-O-α-L-(2'',3''-di-E-p-coumaroyl)-rhamnopyranoside, and caffeic acid were obtained from the methanolic extract of Platanus orientalis L. buds. All the compounds were isolated by column chromatography and identified using 1H-NMR, 2D-1H-NMR (COSY), 1H-13C-NMR, and CIDMS techniques. Cytotoxic and antimicrobial studies were carried out in vitro against human cell lines and against Gram-positive and Gram-negative organisms.
