Platycodon grandiflorum (Korean name, Doraji) has been widely used in traditional herbal medicine as an expectorant for pulmonary disease and a remedy for respiratory disorders in Asia. Here, we investigated the effects of BtOH extract saponin fraction of P. gradiflourm (PGS) on phagocytosis and anti-tumor activity with related cytokine productions in RAW264.7 macrophage cells. The results showed that PGS increased phagocytosis, anti-tumor activity, TNF-${alpha}$ and nitric oxide (NO) production without direct tumor cell cytotoxicity. To further investigate whether NO is involved in anti-tumor and phagocytic activities of PGS, cells were co-treated with specific iNOS inhibitors, L-NIL (N6-(1-iminoethyl)-L-lysine, dihydrochloride), to block NO production. PGS decreased anti-tumor activity in L-NIL-treated cells, whereas phagocytic activity was not inhibited under the same conditions, indicating that the anti-tumor activity by PGS appears to be conducted by NO. These findings suggest that P. grandiflorum could be used a potential nutrition therapeutic agent for cancer patients.
