in vitro confirm that GA, GB, GK, and BB resulted in significant decrease of ROS and increase of SOD activities and proteinlevels ofHO-1 and Nqo1; however, GB group had a significant advantage in comparison with the GA and GK groups. Moreover,after ginkgolides and BB treatments, p-Akt and p-Nrf2 were significantly upregulated, which could be inhibited by LY294002 ina dose-dependent manner, meanwhile, GB exhibited more effective than GA and GK. In vivo, TTC staining indicated that theinfarct volume ratios in MCAO rats were dramatically decreased by GB in a dose-dependent manner. Furthermore, GB significantlyupregulated the protein levels of HO-1, Nqo1, SOD, p-Akt, p-Nrf2, and Nrf2. In conclusion, GA, GB, GK, and BBsignificantly inhibited oxidative stress damage caused by cerebral ischemia reperfusion. Compared with GA, GK, and BB, GBexerts the strongest antioxidant stress effects against ischemic stroke. Moreover, ginkgolides and BB upregulated the levels ofantioxidant proteins through mediating the Akt/Nrf2 signaling pathway to protect neurons from oxidative stress injury.
