Phytochemical investigation of Bignonia binata leaves led to the isolation of three new compounds: including a glycoside of simple alcohol, namely binatoside (2), 3,4-dihydroxy-N-methyl piperidin-2-one (7), and a phenyl ethanoid glycoside, namely bignanoside C (8), alongside with five known compounds; including a glycoside of simple alcohol; (2S) propane-1,2-diol 1-O-(6-O-caffeoy1)-β-D-glucopyranoside (1), phenyl ethanoids; leucosceptoside A (3) and plantainoside C (4), and iridoids; ipolamiide (5) and strictoloside (6). The structure of the isolated compounds was elucidated by various spectroscopic methods, including 1 D and 2 D NMR experiments, HR-ESI-MS as well as by comparison with the literature.
