Five new eudesmane-type sesquiterpenoids from Chinese agarwood induced by artificial holing

Five new eudesmane-type sesquiterpenoids (1–5), along with six known ones (6–11), were isolated from Chinese agarwood induced by artificial holing originating from Aquilaria sinensis (Lour.) Gilg (Thymelaeaceae). The structures of the new sesquiterpenoids were established by spectroscopic methods including UV, IR, MS, 1D, and 2D NMR. Compounds 1, 3, 6 and 7 exhibited antibacterial activities against both Staphylococcus aureus and Ralstonia...
