Six chlorophyll-related compounds isolated from leaves of Neptunia oleracea (Leguminosae) inhibited the activation of tumor promoter- induced Epstein-Barr virus (EBV). Photo-irradiation of pheophorbide a, the major active constituent, did not enhance this inhibitory activity, and thus ruled out any photosensitizing effect playing the major role.
