We investigated 9 kinds of ramie (Boehmeria nivea, (L.) Gaud., Bn; hereafter denoted as Bn) for their protective action against oxidative stress in a cellular system using C6 glial cells. We observed loss of cell viability and high levels of ROS generation after treatment with H2O2 and A├?┬▓25-35. However, treatments with Bn extracts led to an increase in cell viability and decreasein ROS production induced by H2O2 and A├?┬▓25-35. In particular, the extracts of Bn-02 (seobang variety from Seocheon) and Bn-90 (local variety from Yeonggwang) showed excellent anti-oxidative properties. This indicates that Bn extracts could prevent neurodegeneration by reducing oxidative stress in cells.
