摘要：

Five flavonoids were isolated from the ethyl acetate fraction of leaves ofSophora secundiflora; formononetin(1), 5-hydroxy-4'-methoxyflavone(2), genistein(3), 5-hydroxy-8-(1-hydroxy-1-methyl-ethyl)-2-(4-hydroxyphenyl)-4H-furo-[2, 3-h]-chromen-4-one(4)and ononin(5). Additionally, LC-ESI-MS/MS analysis of the ethyl acetate fraction ofS. secundifloraleaves had led to tentative identification of eighteen compounds. Formononetin,S. tomentosaandS. secundifloraleaves methanolic extract were evaluatedin vivofor their neuroprotective activity where formononetin andS. tomentosashowed promising neuroprotective activity with reduction in acetylcholine esterase (AchE) enzyme activity and elevation of acetylcholine (Ach) and glutathione(GSH) brain levels and attenuation of dopamine (DA), nor-adrenaline (NA) and malonedialdehyde (MDA) brain level significantly, HoweverS. secundifloraleaves methanolic extract didn't attenuate the AchE enzyme activity, DA and NA brain levels.
