【摘要】 为筛选蛹虫草(Cordyceps militaris)子实体的抗肿瘤和免疫活性部位,采用系统溶剂法,分别用氯仿、乙酸乙酯、95%的无水乙醇、沸水(100℃)、3%草酸铵和5%NaOH依次提取并计算提取物得率,且测定了沸水提取物、草酸铵提取物、NaOH提取物1和2的多糖含量。采用体外抗肿瘤模型测定了氯仿提取物、乙酸乙酯提取物和乙醇提取物对肿瘤细胞L1210和SW620的抑制活性;采用体外免疫增殖试验模型测定了沸水提取物、草酸铵提取物和NaOH提取物1和2的免疫活性。结果表明,乙酸乙酯提取物对肿瘤细胞L1210和SW620的抑制效果最好,当乙酸乙酯提取物浓度为200μg/mL时,抑制率分别为(85.2±2.5)%和(67.7±6.3)%;体外免疫活性测定结果表明,草酸铵提取物刺激小鼠脾淋巴细胞后的增殖活性最高,当浓度为500μg/mL时细胞增殖率为(312.0±7.2)%,与阳性对照PHA的细胞增殖率(329.3±3.0)%相当。
【Abstract】 A systematic extraction system consisting of successive extractions with three organic solvents(chloroform,ethyl acetate,ethanol) followed by successive extractions with three non-organic solvents(distilled water at 100 ℃,3% ammonium oxalate solution,5% NaOH solution) was used to obtain bioactive components from dry,powdered C.militaris fruit bodies.Evaluation of the inhibitory effects of the organic extracts on L1210 and SW620 cancer cell lines revealed that ethyl acetate extracts were most eff...
