Abstract: 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.

Key words: Clerodendrum serratum, Verbenaceae, Clerodenrum, Iridoid glucoside, Phenylpropanoid glycoside, 2D-NMR
