对来源于缘毛紫菀Aster souliei、萎软紫菀A.flaccidus和块根紫菀A.asteroides的藏紫菀药材进行了鉴别研究。参照《中国药典》2010年版附录相关方法,对药材进行了性状观察和描述,拍摄了药材照片;对药材粉末进行了显微观察,描述了主要显微特征,并制备了粉末显微图谱;以灯盏甲素和绿原酸为指标性成分,采用薄层色谱法建立了藏紫菀的薄层色谱鉴别方法。3种来源藏紫菀在药材性状和粉末显微特征方面均具有一定的区别,二者结合可以较好的区分3种不同的来源;薄层色谱鉴别结果显示,来源于缘毛紫菀和萎软紫菀的药材薄层色谱图较为一致,块根紫菀具有一定差别。该实验建立的性状、显微和薄层色谱鉴别方法简便、准确、重复性好,可方便、有效地区别3种不同来源的藏紫菀药材。
The Aster souliei, A.flaccidus and A. asteroides from Aster souliei were identified. According to “Chinese Pharmacopoeia” 2010 edition appendix related methods, the traits were observed and described the traits, taken pictures of medicinal herbs; microscopic observation of medicinal powder, described the main microscopic features, and prepared a powder micrograph; Eriochrome and chlorogenic acid were selected as the index components, and thin layer chromatography was used to establish TLC identification method. The three sources of Aster tigris have some differences in medicinal properties and powder microscopic features, the combination of the two can better distinguish between three different sources; TLC identification results show that derived from Asphodelphalus and Wilcox The TLC chromatogram of medicinal herbs is more consistent, aster root has some differences. The established traits, microscopic and TLC identification method is simple, accurate, reproducible, and can be easily and effectively distinguish between three different sources of Tibetan aster medicine.
