This study was conducted to investigate the growth and physiologycal activitis of Aruncus dioicus var. kamtschaticus (Maxim.) H. Hara under the NaCl treatment conditions (0, 100, 200, 300 mM). After 30 days treatment, the growth and physiologycal activitis were investigated. In the growth of plants, the plant height, leaf width, leaf length and ion level were reduced at NaCl treatments of more than 100 mM. The total polyphenol content was decreased by NaCl in a concentrationdependent manner compared to the control group. The contents of total flavonoids did not show any difference at the concentration of 200 mM and 300 mM. However, the content of total flavonoid decreased compared with that of control. In antioxidant activity, the DPPH and ABTS radical scavenging activity and reducing power activity were decreased by NaCl concentration compared to the control. When changes in the content of NO production was monitored by ELISA, production inhibitory effect was 94.5%, 70%, 63%, 56.9% in NaCl concentration of 0, 100, 200, 300 mM, respectively. The growth, ion level, antioxidant and anti-inflammation activity of Aruncus dioicus var. kamtschaticus was reduced at NaCl treatments of more than 100 mM.
