摘　　要：利用柱色谱分离技术首次对吉林省西部地区白城市7月份马齿苋全草的乙醇萃取物进行提取、分析,通过选用醇、醚、酯等溶剂和洗脱剂,选用硅胶、凝胶、聚酰胺、大孔树脂等吸附剂进行分离、纯化,经理化测试和波谱分析确定了其主要成分和结构.实验结果显示,该地区马齿苋主要含有木栓酮(1)、4α-甲基-3β-羟基-木栓烷(2)、正二十六烷醇(3)、山萘酚(4)、槲皮素(5)、木樨草素(6)、正三十烷醇(7)、β-谷甾醇(8)和胡萝卜苷(9)等9种单体化合物.其中化合物8和9含量最高.The constituents of ethanol extraction from the whole plant of purslane are extracted and analyzed by using column chromatography separation technology for the first time.The purslane is from Baicheng city of Jilin province in the western region in July.By choosing alcohol,ether,ester as solvents and eluents,selecting the silica gel,gel,polyamide and macroporous resin as adsorbents for separation and purification,its main composition and structure are determined by physical and chemical testing and spectrum analysis.Experimental results show that the purslane mainly contains 9kinds of monomer compounds which are friedelin（1）,4α-methyl-3β-hydroxylfriedelan（2）,1-hexacosanol（3）,kaempfeml（4）,quercetin（5）,luteolin（6）,1-Triaconal（7）,β-sitosterol（8）and daucosterol（9）,and the major constituents are compounds 8 and 9.
