International audience. Three unusual dioxatricyclodecenone compounds, mollugoside A, E-mollugoside B and Z-mollugoside B and, together with known flavonoids, were isolated from the aerial parts of Galium mollugo collected in north-eastern Algeria. Their structures were elucidated by analysis of spectroscopic data, including 1D and 2D NMR. Flavonoids and mollugoside A significantly reduced reactive oxygen species (ROS) generation in human fibroblasts.
