[Development of a rapid screening method for discovering neuroprotective components from traditional Chinese...

This study developed a method for rapid screening neuroprotective compounds with FDA (fluorescein diacetate) labeled SH-SYSY cells, which was injuried by Glu (L-glutamic acid). The cell viability was determined by fluorescence automatic mi-croscopy screening system. Then, neuroprotective components from Gegen Qinlian decoction were screened by the proposed method. The results demonstrated that 4 chemical components, C15, D06, D07 and E05 from Gegen Qinlian decoction, showed significantly neuroprotective effects. Furthermore, 8 compounds (i. e. daidzin, 3'-methoxydaidzin, liquiritin apioside, 6-C-L-alpha-arabinopyranosyl-8-C-beta-D-glucopyranosyl chrysin, isoliquiritin apioside, baicalin, oroxylin-A-7-O-fP-D-glucuronide and wogonoside) were identified from these active components by LC-Q/TOF-MS technology (liquid chromatography quadrupole time of flight tandem mass spectrometry). These 8 compounds may be the potential neuroprotective substances in Gegen Qinlian decoction.
