ResumoAIM: To study the water-soluble constituents of the aerial parts of Clerodendranthus spicatus. METHOD: The water soluble fractions were subjected to a series of chromatographic separation methods to afford six caffeic acid depsides, as well as free caffeic acid. Their structures were elucidated mainly by spectroscopic methods. RESULT: Seven compounds: caffeic acid (1), rosmarinic acid (2), methyl rosmarinate (3), methyl lithospermate (4) and dimethyl lithospermate (5), methyl lithospermate B (6), dimethyl lithospermate B (7) have been isolated from Clerodendranthus spicatus. CONCLUSION: Compounds 3～7 have been isolated from this plant for the first time.
