	<span style="line-height:1.5;">Hydrogen peroxide (H2O2) is a signal molecule that plays a crucial role in plant secondary metabolism. In order to explore the signaling mechanism of endophytic fungal elicitors (Penicillium commune 2J1) for promoting 1,8-eucalyptus accumulation in C. longepaniculatum, changes in the contents of H2O2 and 1,8-eucalyptus were investigated after the addition of elicitors to the C. longepaniculatum cultures. The experimental results showed that the 1,8-eucalyptus contents in C. longepaniculatum cells were increased upon addition of the endophytic fungal elicitors into the culture. It¡¯s maybe through Hydrogen peroxide (H2O2) signal molecule. When different concentrations of elicitors were added to C. longepaniculatum suspension cells, the changes in the content of H2O2 and 1,8-eucalyptus showed the same trend, and both reached the highest value at 40 mg/L of elicitor concentration, indicating that the endogenous fungal elicitors affect the accumulation of 1,8-eucalyptus through H2O2 signaling molecular pathway. When CAT was added, the 1,8-eucalyptus decreased but was not completely inhibited, indicating that the elicitors also have other signaling pathways.</span>
