Abstract

Abstract This study presents the results of our comparative evaluation of diagnostic morphological characteristics of raw material from 11 species of genus Thymus L. of medicinal and raw material importance occurring in Ukraine. The following taxa were evaluated: T. serpyllum L., T. odoratissimus Mill. (T. glabrescens Willd.), T. borysthenicus Klokov & Des.-Shost., T. pallasianus Heinr. Braun, T. moldavicus Klokov & Des.-Shost., T. calcareus Klokov & Des.-Shost., T. alpestris Tausch ex A. Kern., T. × dimorphus Klokov & Des.-Shost., T. pannonicus All. s.l. (including T. marschallianus Willd.), T. pulegioides L. and T. roegneri K. Koch (T. alternans Klokov). Among wild species of thyme, only raw material of Thymus serpyllum is officially allowed for use with the purpose for production of pharmaceuticals and medicines. A comparison of the main characteristics is particularly important in view of the fact that raw material is represented by parts of plants (stems, leaves and flowers), which makes any whole comparison of species hardly possible. This study has revealed that stem pubescence, calyx structure, configuration/arrangement and type of leaf venation can provide valuable information for diagnostics of raw material of Thymus species. The results exhibited that according to characters of stem pubescence, calyx structure, shape and size of leaves the most similar are raw material samples of T. serpyllum and T. moldavicus. However, these species are rather well separated geographically, so the possibility of mixing of their raw material is negligible. Other species have significant morphological differences in certain characteristics by which they can be diagnosed in the raw material.

乌克兰最常见百里香属植物原始部分的比较形态学研究

摘要本研究介绍了我们对乌克兰11种具有药用和原料重要性的百里香属原料的诊断形态学特征的比较评估结果。对以下分类群进行了评价：沙蚕（T.serpyllum L.）、臭蝶（T.odoratisimus Mill）。（格拉布雷森斯），博里斯特尼库斯·克洛科夫和德斯-Shost。，T.pallasianus Heinr。Braun，T.moldavicus Klokov&Des-Shost。，T.calcareus Klokov&Des-Shost。，T.alpestris Tausch ex A.Kern。，T.×dimorphus Klokov和Des-Shost。，T.pannonicus全部。s.l.（包括T.marschallianus Willd.）、T.pulegioides l.和T.roegneri K.Koch（T.alternans Klokov）。在野生百里香中，只有百里香的原料被官方允许用于生产药品。鉴于原材料以植物的部分（茎、叶和花）为代表，对主要特征进行比较尤为重要，这使得几乎不可能对物种进行任何整体比较。本研究表明，茎的短柔毛、花萼结构、叶脉的构型/排列和类型可为诊断百里香属植物的原料提供有价值的信息。结果表明，从茎毛的性状、花萼结构、叶片的形状和大小来看，最相似的是沙蚕和霉的原料样品。然而，这些物种在地理上分离得很好，因此它们的原材料混合的可能性可以忽略不计。其他物种在某些特征上存在显著的形态差异，通过这些特征可以在原料中进行诊断。
