Three C-17 diacetylenic compounds (1–3), one monoterpenoid (4), seven ceramides (leucoceramides A–G, 5a–g), six cerebrosides (leucocerebrosides A–F, 6a–f) and nine known compounds were isolated from the methanolic extract of Hydrocotyle leucocephala. Their structures were established by spectroscopic methods. The isolated compounds 1–3, 5a–g, 6a–f and 7 were shown to be active in the lipopolysaccharide (LPS) induced cytokine production assay for IL-10, IL-12, and TNF-α.
