Four compounds were obtained from the leaves of Clerodendrum serratum. By means of spectroscopic techniques(such as IR, UV, MS, 1H NMR , 13C NMR and 2D-NMR) and chemical evidences, their structures were elucidated as 7-O-p-coumaroyloxyugandoside(1), 7-O-cinnamoyloxyugandoside(2), acteoside(3) and martynoside(4) respectively. Compounds 1 and 2 were new iridoid glucosides, compunds 3 and 4 were phenylpropanoid glycosides which were obtained for the first time from this plant.
