The aim of the study was to screen active components of Radix Bupleuri (a traditional Chinese herb) and discover novel anti-schizophrenic candidate drugs using human neuroblastoma SH-SY5Y cells. SH-SY5Y cells were used for preparation of the stationary phase in the cell membrane chromatography model. Retention components by the SH-SY5Y/CMC model were collected and then analyzed by GC/MS under the optimized conditions in offline conditions. After investigating the suitability and reliability of the SH-SY5Y/CMC method using amisulpride and haloperidol as standard compounds, this method was applied to screening active components from the extracts of Radix Bupleuri. Retention components of SH-SY5Y/CMC model were saikosaponin A, saikosaponin B1, saikosaponin B2, saikosaponin C and saikosaponin D, which were identified by the GC/MS method. In vitro pharmacological trials-MTT, saikosaponin B1, saikosaponin B2 and saikosaponin C could protect SY5Y cells. The protective effects of saikosaponin B1 and saikosaponin C were concentration dependent. Saikosaponin A and saikosaponin D inhibited cell viability at concentrations >30μg/mL (p<0.05). Via SH-SY5Y/CMC method and SH-SY5Y MTT trial, we rapidly detected target components from Radix Bupleuri, accurately identified them and determined their different effects on SH-SY5Y cells. Saikosaponin B1, saikosaponin B2 and saikosaponin C may be anti-schizophrenic candidate drugs. © 2015 John Wiley & Sons, Ltd.
