Abstract
A new biflavonoid named pancibiflavonol (1) was isolated from an EtOH extra ct of the stem bark of Calophyllum panciflorum, along with six known biflav onoids, and its structure was elucidated by spectroscopic methods. These bi flavonoids all exhibited significant inhibitory activity against 12-O-tetra decanoylphorbol-13-acetate-induced Epstein-Barr virus early antigen activat ion in Raji cells.
