Inhibitory activity of glyceollins against AChE in mouse brain cortical and hippocampal homogenates. Neuronal cells isolated from either cortical or hippocampal regions were homogenated and used for assaying the inhibitory activity of glyceollins against AChE. Values are mean ± SD (n = 7). Different alphabetical letters (a–f) on bars indicate significant differences. Cortical and hippocampal neuron cells were isolated from the mouse brain and their homogenates were used for assaying the inhibitory activity of glyceollins against AChE.
