Results The IC50 of SPG-Rg3 was (155.7±0.71) mg·L-1,when the concentration of SPG-Rg3 was arranged from 37.5 to 600.0 mg·L-1,the growth inhibitory rate of MCF-7 cells was higher following the increase of its concentration,the cell growth was greatly inhibited compared with control group(P.05); cell cycle was changed,the cell number of S period increased compared with control group(P.01),the cell number of G2/M period decreased compared with control group(P.01),in experiment group there was an apoptotic apex before G1 apex,and the number of apoptotic cells increased; most of cell nuleus in SPG-Rg3 (150 mg·L-1)experiment group appeared yellow or chrysoidine fluorescence,contracted,beaded and crescent; the result of immunocellularchemical staining of caspase-8 indicated that caspase-8 protein had no expression in control group,but stronger expression in SPG-Rg3 group.

结果：SPG-Rg3 IC50为（155.70±0.71） mg·L-1，当SPG-Rg3浓度在37.5~600.0mg·L-1时，MCF-7细胞的生长抑制率随SPG-Rg3浓度的增加而增大，与对照组比较，细胞增殖受到明显抑制（P.05）；MCF-7细胞的生长周期也发生变化，S期细胞数增加，明显高于对照组（P.01，G2/M期细胞数则明显少于对照组（P.01；并且在G1峰前出现明显的凋亡峰，凋亡细胞数增加。
