The genus Teucrium L. is a well-known medicinal plant belonging to Lamiaceae family and Ajugoideae subfamily. The present study aims to evaluate the taxonomic status of the Teucrium species using both morphological and flavonoid characteristics and to determine the flavonoid classes. A total of 64 accessions belonged to eight species, and five subspecies were collected from different Zagros regions, Iran. Twenty-nine quantitative and qualitative morphological characters were studied. Extraction of leaf flavonoid was accomplished using a rotary evaporator and MeOH 90%. Identification of the chemotaxonomic position and flavonoid class of Teucrium species was investigated by thin layer chromatography, column chromatography and High Performance Liquid Chromatography-Micromass Quattro micro Atmospheric Pressure Ionization Mass Spectrometer. All information was analyzed using NTSYS pc. 2, PAST v.3.18 and Cluster Vis v. 1.8.2. According to the findings, T. polium accessions significantly revealed the highest value of morphological and flavonoid variations. All subspecies of T. orientale were definitely separated, but some relationships were observed between its subspecies, including taylori and glabrescens. All members of two sections of Polium and Teucris were definitely recognized. A total of seven flavonoid classes were determined from which the highest amounts of abundance were attributed to flavones (18) and isoflavones (17). In conclusion, morphological and flavonoid markers were introduced as appropriate characteristics in the taxonomic relationships of Teucrium species. All the evidence of the present research was first described for Iran.

伊朗扎格罗斯地区一些Teacrium L.（Lamiaceae）的形态和化学分类研究

属香科科属L.是一个著名的药用植物属于唇形科和亚科Ajugoideae。本研究的目的是评估的分类地位香科科属使用这两种形态和类黄酮特性的物种，并确定黄酮类。共有64个种属，属于8个种，从伊朗扎格罗斯不同地区收集了5个亚种。研究了29个定量和定性的形态特征。叶黄酮的提取是使用旋转蒸发仪和90％的MeOH进行的。在化学分类位置识别和黄酮类的香科科属通过薄层色谱法，柱色谱法和高效液相色谱-微质量Quattro微型大气压电离质谱仪研究了该菌种。使用NTSYS pc分析所有信息。2，PAST v.3.18和Cluster Vis 1.8.2。根据这些发现，T虫的种质显着揭示了形态和类黄酮变异的最高值。东方锥虫的所有亚种都被明确地分开，但是在其亚种之间观察到了一些联系，包括泰勒罗氏菌和甘草。Polium和Teucris两个部分的所有成员被肯定。总共确定了7种类黄酮，其中最高的丰度归因于黄酮（18）和异黄酮（17）。总之，形态学和类黄酮标记被引入作为Te属分类学关系中的适当特征。本研究的所有证据都是首先针对伊朗描述的。
