SH-SY5Y cells were used for preparation of the stationary phase in the Cell Membrane Chromatography (CMC) model.
METHODS AND RESULTS:
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 protect effect of saikosaponin B1 and saikosaponin C were concentration dependent. Saikosaponin A and saikosaponin D inhibited cell viability at concentrations greater than 30 μg/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 found out their different effects on SH-SY5Y cells.
CONCLUSIONS:
Saikosaponin B1, saikosaponin B2 and saikosaponin C may be as anti-schizophrenic candidate drugs. |
