摘要

Our ongoing phytochemical investigation on the twigs and leaves of Euphorbia fischeriana led to the isolation of one new alkylresorcinol dimer, fiseuphenol (1), along with four known flavones (2–5) and three coumarins (6–8). Their structures were identified on the basis of extensive spectroscopic data, including NMR as well as HR-ESI-MS. Compound 1 was the first example of an alkylresorcinol dimer from the Euphorbiaceae plants.
