The results showed that the four stereoisomers of soman were well separated under the defined chromatographic conditions. CP-）soman was only detected stereoisomer in the intoxicated rabbit blood and eliminated rapidly, the toxicokinetics could be described by a two-compartment model after rabbits received soman via vein.

结果可见梭曼4个异构体在确定的气相色谱条件下得到了较好地分离；给兔iv梭曼43.2 μg·kg-1后，血中仅测到一对CP梭曼，其消除过程符合二室开放模型， V d=2.1 L·kg-1， t 1/2α=4.5 s， t 1/2β=72 s， AUC(15～300 s)=2.08 mg·s·L-1， CL =21 mL·kg-1·s-1，血中CP梭曼在血中消除过程反映了机体对梭曼毒性异构体的解毒过程。
