Isoflavonoids from Dalbergia olivari.
Two isoflavonoids, named olibergin A (1) and B (2) were isolated from the stem bark of Dalbergia oliveri (Leguminosae). Along with three previously known compounds, they are inhibitors of Epstein-Barr virus early antigen activation induced by 12-O-tetradecanoylphorbol-13-acetate in Raji cells. Their structures were elucidated on the basis of spectroscopic analyses.
