Neuroprotective effects of isolated compounds from G. laxum in HT22 cells. a Cells were treated with each isolated compound from G. laxum at 10 or 20 μM in the presence or absence of 10 mM glutamate for 12 h. Values expressed to AV ± SD. N = 3, the significance was presented as ***p < 0.001 compared to the control, ### p < 0.001 compared to the glutamate-treated cell group. b Cells were treated with compounds 2, 4, 6, and 11 at 1, 5, 10, and 20 μM in the presence of 10 mM glutamate for 12 h. Values expressed to AV ± SD. N = 3, the significance was presented as ***p < 0.001 compared to the control, # p < 0.05 and ### p < 0.001 compared to the glutamate-treated cell group
