Abstract :
A phenolic fraction purified form defatted seeds of Oenothera biennis promoted selective apoptosis of human and mouse bone marrow-derived cell lines following first-order kinetics through a caspase-dependent pathway. In non-leukemia tumour cell lines, such as human colon carcinoma CaCo2 cells and mouse fibrosarcoma WEHI164 cells, this fraction inhibited 3H-thymidine incorporation but not cell death or cell cycle arrest. Human peripheral blood mononuclear cells showed low sensitivity to treatment. Single bolus injection of the phenolic fraction could delay the growth of established myeloma tumours in syngeneic animals. HPLC and mass spectrometry analysis revealed that the fraction contains gallic acid. However, the biological activity of the fraction differs from the activity of this phenol and hence it should be attributed to other co-purified molecules which remain still unidentified.
