Abstract: The aim of this paper was to establish the corticosterone-induced damage model in PC12 cells and study the protective activity of alcohol extracts and its fractions from Cajanus cajan on corticosterone-induced PC12 cells. PC12 cells were exposed to different concentrations of corticosterone to determine the optimum concentration of establishing the damage model, and then the injured PC12 cells were incubated with the alcohol extract and its fractions for 24 h. After that the neuroprotective effect on injured PC12 cells was investigated by morphological observation, LDH detection and MTT determination. The results showed that the survival rate of PC12 cells and the cells exposed to corticosterone (100 μmol/L) for 48 h decreased obviously, with an increase in lactate dehydrogenase (LDH) level, but the effect became weak when the alcohol extracts and its fractions from the C. cajan was added to the PC12 cells, and it was in a dose-dependent manner. The author suggests that the alcohol extract and its fractions from C. cajan can generate a neuroprotective effect on injured PC12 cells induced by corticosterone, and that of alcohol extract is the most significant.
