苍耳子与蒙古苍耳子的比较鉴别

Comparison of Achene of Xanthium Sibiricum and That in Mongolia

采用性状、显微、薄层色谱法和分光光度法对正品苍耳子和习用品蒙古苍耳子进行比较鉴别,以求证苍耳与蒙古苍耳并用的合理性。结果:苍耳子与蒙古蒙耳子性状差别显著,表明其植物基源不同,其性状特征主要依据果实的大小;喙的特点、长短;总苞制的疏密、粗细、长短等,可以对2种苍耳子进行鉴别;显微特征表明,蒙古苍耳子腺毛由双列细胞细成,而苍耳子腺毛头部由单列扁平细胞组成,而腺柄为双列细胞组成;二者薄层色谱和紫外光谱差异较大,因此说明蒙古苍耳与苍耳子成分差异较大,不可混用。

Take form, feature, microscope demonstration, thin Layer chromatography and spectrophotometric method to compare the Achene of Xanthium Sibiricum and that in Mongolia for reasonability of using them together. The result shows there＇s marked difference in their character,indicating their different plant source;you can identify them on fruit size. beak size and features, shape of bud;the microscope shows that the Achene of Xanthium Sibiricum of Mongolia has gland hair consisting of double-column cells, while the other, the head of flat cells, but the handle of double-column cells ; there＇s great difference on thin layer chromatography and ultra-violet spectrograph,showing both have different components,can not be used together.
