Two new sesquiterpenoids with guaiane skeletons-holosericin A (1) and holosericin B (2)-were isolated from the medicinal plant Daphne holosericea (Diels) Hamawa (Thymelaeceae). Their structures were elucidated by 1D and 2D-NMR spectroscopy, as well as HR-ESI-MS data. Compounds 1 and 2 were evaluated for inhibitory activities against acetylcholinesterase and compound 2 showed a moderate activity with 31% inhibition.
