Light microscopy is in most cases a quick method for the identification and discrimination of medicinally used plant drugs; moreover, this technique is very inexpensive. Reliable descriptions of the anatomy of plants and their adulterations are prerequisites for necessary purity controls.
The anatomy of the subterranean organs of 18 pharmaceutically useful as well as related but inconsiderable Asteraceae species from nine genera (Taraxacum F. H. Wigg., Leontodon L., Scorzoneroides Moench, Hypochaeris L., Crepis L., Aposeris Neck., Cichorium L., Scorzonera L., and Tragopogon L.; tribe Cichorieae, Asteraceae) is described in detail and graphically illustrated. Features characterizing and discriminating the studied taxa are presented and discussed.
The roots/rhizomes of various species were examined by means of light microscopy.
Useful anatomical characters were found for the discrimination between the species, and some of them were examined for the first time.
Discrimination of most genera and species investigated was possibly based on the anatomy of their underground parts. The identified characters may be effectively used for quality control of commercial drugs and the identification of adulterations.
在大多数情况下，光学显微镜是一种快速识别和区分药用植物的方法；此外，该技术非常便宜。对植物解剖结构及其掺杂物的可靠描述是必要纯度控制的前提条件。
描述来自九个属（蒲公英属 F. H. Wigg.、山莴苣属 Leontodon L.、山苦荬属 Scorzoneroides Moench、苦荬菜属 Hypochaeris L.、小甘菊属 Crepis L.、假茼蒿属 Aposeris Neck.、菊苣属 Cichorium L.、山苦荬属 Scorzonera L. 和乳苣属 Tragopogon L.；菊科旋覆花族）的 18 种药用植物及相关但不太重要的 Asteraceae 种地下器官的解剖结构，详细描述并以图形表示。介绍并讨论了特征描述和区分研究分类群的特征。
用光学显微镜检查各种物种的根/根茎。
发现了用于区分物种的有用解剖特征，其中一些是首次检查的。
所研究的大多数属和种的鉴别可能基于其地下部分的解剖结构。鉴定出的特征可有效用于商业药物的质量控制和掺杂物的鉴定。
