RESUMO
Three new biflavonoids, umcephabiovins C - E (1 - 3), along with fourteen known compounds were isolated from the twigs and leaves of Cephalotaxus oliveri. Their structures and configurations were elucidated by UV, IR, NMR, ECD, and HR-ESI-MS spectra. Compounds 1 - 3 exhibited significant α-glucosidase inhibitory activity with IC50 values of 7.05 ± 2.66, 24.45 ± 4.73, and 1.84 ± 1.14 µM, respectively. Compound 11 showed moderate cytotoxicity against the BaF3/T315I cell line.
