The antioxidative activity in Eleutherococcus sciadophylloides (Franch. & Savat.) H. Ohashi. was assessed by the β-carotene degradation method and DPPH radical scavenging activity. Its methanolic extract showed a high antioxidative activity and its component was chlorogenic acid. Effect of temperature, light and cutting length on the chlorogenic acid concentration in young shoots was tested in a growth chamber. Intense light and long cutting increased the concentration of chlorogenic acid. Based on these findings, culture conditions suitable for forcing were investigated in green house. Young shoots that contain a high concentration of chlorogenic acid could be harvested in forcing culture by planting 30~40 cm-long cuttings in 10~15 degree C water.
