摘 要:以无花果残渣为原料,研究了无花果渣脂溶性物质抗肿瘤成分的提取和纯化方法,经过多次柱层析和波谱结构分析,得到13种单晶体。通过对13种单晶体对白血病细胞(U937)、肺癌细胞(95D)和胃癌细胞(AGS)的体外抗肿瘤试验,结果表明,晶体6的结构鉴定为β-谷甾醇,对肿瘤细胞株U937、95D和AGS抑瘤活性的半数抑制质量浓度(IC50)值小于10mg/L,具有抑瘤效果。提取无花果渣脂溶性抗肿瘤成分的最佳工艺为:提取溶剂为石油醚(沸程60~90℃),果渣粒度750μm、提取温度85℃、提取时间130min、料液比1∶11(g∶mL)、提取2次,粗提物得率为23.1g/kg。Extraction and purification technology of lipid-soluble anti-tumor active components from fig residues were studied. Thirteen crystals were got after column chromatography, spectrometric study and structural analysis. The anti-tumor activity of these 13 crystals was investigated on blood tumor cell line(U937), lung tumor cell line(95D)and stomach tumor cell line(AGS)in vitro. The Number 6 crystal was identified as β-sitosterol and validated as anti-tumor component for its fifty percent inhibition content (IC50)lower than 10mg/L. The optimum lipid-soluble anti-tumor components extraction condition are as follows, using petroleum ether(boiling point from 60 to 90℃) as solvent and the fig residues granularity 750μm, extracting temperature 85℃, extracting time 130min, the ratio of solid to solvent 1∶11(g∶mL), extracting twice. As a result the anti-tumor substance extraction yield is 23.1g/kg. The anti-tumor component was identified as β-sitosterol after column chromatography, spectrometric study and structural analysis.
