Abstract  The viability rate of SGC７９０１ gastric cancer cells was used as an index , the anti‐gastric cancer ingredients from the water chestnut shell were reclaimed by semi‐bionic extraction . The effects of extraction time , ratio of water to water chestnut shell , amount of pepsin and trypsin on extraction antigastric cancer activity were investigated , and the uniform designation was employed to determine the optimum extraction conditions . The results showed that when １ g shell powder was added to １０ mL solvent (１ ∶ １０ ratio of powder to pH ≈ ２ solvent) in the absence of pepsin , extracting for ３０ min at ３７℃ , and then being centrifuged to collect precipitate , adding １０ mL pH ≈ ８ solvent and ４％ trypsin , extracting for ３０ min at ３７ ℃ , the extracts had the highest activity against gastric cancer and the cell
viability was the lowest ,i .e . ４５.５２％ .Also , this experiment confirmed that water chestnut shell extracts still had a high activity of inhibiting the growth of gastric cancer cells through semi‐bionic extraction .

均匀设计法优选菱壳中抗胃癌成分的半仿生提取工艺

以SGC７９０１ 胃癌细胞存活率为指标,运用半仿生提取方法回收菱壳中的抗胃癌活性成分,考察提取时间、料液比、胃蛋白酶用量、胰蛋白酶用量对提取物抗胃癌活性的影响,并运用均匀设计法确定其最佳提取工艺.结果表明:菱壳与pH ≈ ２ 提取液按料液质量体积比１ ∶ １０ ,不加入胃蛋白酶,３７ ℃ 提取３０ min 后,离心收集沉淀,添加４％ 胰蛋白酶,菱壳与pH ≈ ８ 提取液按料液质量体积比１ ∶ １０ ,３７ ℃提取３０ min ,可获得最佳抑制效果,细胞存活率仅为４５.５２ ％ .本实验表明,采用半仿生法提取菱壳中的抗胃癌活性成分是可行的.
