Objectives : Bang-poong (Saposhnikovia divaricata; SD) was traditionally used to treat inflammatory disorders. In this study, we aimed to investigate whether Bang-poong and related species including SD, Glehnia littoralis (GL), and Peucedanum japonicum (PJ) possess neuroprotective effects and acetylcholinesterase (AChE) inhibitory activities. Methods : Roots of SD, GL and PJ were extracted with distilled water (DW) or 70% ethanol (EtOH). We assessed 2,2-diphenyl-1-picrylhydrazyl (DPPH) free radical scavenging activities of the extracts. To examine neuroprotective effects, we measured cell viability in PC12 or HT22 cells after treatment of the extracts with $H_2O_2$ or amyloid-beta ($A{\beta}$). To assess anti-neuroinflammatory effects, we measured the nitric oxide (NO) levels after treatment with the extracts and lipopolysaccharide (LPS) in BV2 microglial cells. In addition, we performed AChE inhibition assay to explore effects of the extracts on the cholinergic system. Results : DW and EtOH extracts of SD, GL and PJ showed mild DPPH free radical scavenging activities. Also, DW extracts of GL and PJ showed protective effects against $H_2O_2$-induced toxicity in PC12 cells. In LPS-activated BV2 cells, EtOH extracts of SD, GL and PJ exerted inhibitory effects on NO production. Meanwhile, DW extracts of SD, GL and PJ inhibited the $A{\beta}$-induced cell death in HT22 cells. In addition, DW and EtOH extracts of GL exhibited remarkable inhibitory activities on AChE. Conclusions : We demonstrated that SD, GL and PJ exert anti-oxidative, anti-neuroinflammatory and AChE inhibitory activities. These results indicate that SD, GL and PJ could be potential candidates for neurological disorders.
