Abstract Seven new monoterpene phenyl ethers, namely micranthumnins A-G (1-7), were isolated from the stem bark of Illicium micranthum (Illiciaceae). Their structures were elucidated by comprehensive spectroscopic analyses including MS, IR, 1D and 2D NMR. All compounds were evaluated for their anti-AChE activities.
