Two new daucane sesquiterpenoids from Daphne aurantiaca.
Two new daucane sesquiterpenoids 1β,2β-epoxy-10(H)α-dauca-11(12)-ene-7α,14-diol and 1α,2α-epoxy-10(H)α-dauca-11(12)-ene-7α,14-diol were isolated from the plateau medicinal plant Daphne aurantiaca Diels. (Thymelaeceae). Their structures were elucidated by 1D and 2D NMR spectroscopy, as well as HR-ESI-MS data.

متن کاملTwo new guaiane sesquiterpenoids from Daphne holosericea (Diels) Hamaya.
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...
متن کاملChemical constituents investigation of Daphne tangutica.
A phytochemical study of an ethanol-soluble extract from the root barks of Daphne tangutica Maxim., a traditional Tibetan herb medicine, led to the isolation of 30 compounds, including eight daphnane diterpenes, nine coumarines, six lignans, five phenylpropanoid derivatives, beta-sitosterol and p-hydroxy benzonate. Two compounds out of these isolates are new daphne diterpene analogs, and their ...
