复方桐叶烧伤油中桐叶麻油两组分同时薄层色谱鉴别

以桐叶药材、熊果酸、芝麻素为对照品，采用薄层色谱方法对复方桐叶烧伤油中的桐叶、麻油进行定性鉴别，并吸取供试品溶液和对照品溶液点于硅胶G薄层板，以环已烷—乙醚—乙酸丁酯—冰醋酸（体积比为20∶5∶4∶0.2）为展开剂进行实验.展开结果显示，供试品溶液色谱中各斑点分离度好、斑点清晰，熊果酸R_f=为0.45，芝麻素R_f为0.23，复方桐叶烧伤油供试品色谱与对照药材、对照品色谱在相应位置上显现出相同颜色的斑点.鉴别方法操作简便，重现性好，可用于复方桐叶烧伤油的质量控制.

Simultaneous TLC Identification of Paulownia Leaf and Sesame Oil in Compound Tongye Burn Oil

Qualitative identification of paulownia leaf and sjianyesame oil in compound Tongye burn oil was carried out by thin layer chromatography with medicinal tung leaf,ursolic acid and sesamin as reference materials.Silica gel G thin layer plate was used.The developer was cyclohexane ether butyl acetate glacial acetic acid (20∶5∶4∶0.2).The results showed that all spots in the solution chromatography of the test sample were separated clearly,ursolic acid R_f=0.45,sesamin R_f==0.23,Spots of the same color are displayed on the corresponding positions of the reference medicine and the reference substance.This method is simple and reproducible,and can be used for the quality control of compound Tongye burn oil.
