本实验以体外培养的人胃腺癌细胞株SGC－7901为材料，研究了八种蔬菜粉脂溶性粗提物（VPFE）对人胃癌细胞体外增殖的影响。VPEE的剂量（以培养液中卜胡萝卜素浓度计）为2×10~(－8)、2×10~(-7)、2×10~(-6)mol／L。结果：（1）生长曲线实验中，八种菜粉VPFE对胃癌细胞的增殖均有抑制作用。在VPFE高剂量组，各种菜粉的抑制作用均有显著性意义（P＜0.05），而中剂量组的作用在不同菜粉有一些差异；（2）集落形成实验中，冬寒菜、菠菜和紫油菜粉VPFE各剂量组均抑制了胃癌细胞的集落形成（P＜0．01），抑制作用呈剂量一反应关系。本次研究的结果为蔬菜防癌抗癌的实际运用积累资料。
In this experiment, in vitro cultured human gastric adenocarcinoma cell line SGC-7901 was used to study the effects of eight kinds of vegetable fat-soluble extracts (VPFE) on the proliferation of human gastric cancer cells in vitro. The dose of VPEE (in terms of the concentration of carotene in the culture fluid) was 2×10 -8, 2×10 -7, and 2×10 -6 mol/L. Results: (1) In the growth curve experiment, eight kinds of rapeseed meal VPFE could inhibit the proliferation of gastric cancer cells. In the high-dose VPFE group, the inhibitory effects of various meals were significant (P<0.05), while in the middle-dose group, there were some differences in the different meals; (2) in the colony formation experiment, the winter cold dish, Both spinach and purple rapeseed powder VPFE inhibited the colony formation of gastric cancer cells (P<0.01). The inhibitory effect was dose-response. The results of this study accumulated information on the practical use of anti-cancer and anti-cancer vegetables.
