Two new 2-arylbenzo[]furans from and their anti-hepatocellular carcinoma and anti-oxidant effects.

Two new 2-arylbenzo[]furans (-) and ten known compounds (-) were identified from the 95% EtOH extract of the branches and leaves of for the first time. Their structures were determined mainly based on extensive analyses of UV, IR, 1D/2D NMR and HRMS spectra. The results of MTT assays demonstrated the anti-tumor potential of compound with good selectivity, which displayed moderate inhibitory effects on proliferation of SK-hep-1 cells with IC value of 22.
