Investigating the compounds present in the essence of flowering branches of four different types of Staychs plant, considering its taxonomic aspect in the North-Western part of Iran
Notice bibliographique
Résumé
Field and purpose: Plant systematic discussion, and taxonomy, in turn, as an important tool in studying various types of morphological characteristics, tries to better characterize different types of plants. Unlike previous classification systems, the current ones not only depend on the morphological characteristics, but also implement other biological characteristics of the plants in their classification. In this regard, taking into account their evolutionary aspects, genetic affiliations and chemical structure is more important. This study investigates the compounds present in the essence of flowering branches of four different types of Staychs plant, considering its taxonomic aspect in the North-Western part of Iran. Methodology: The essence of four species - Stachys Inflate, Stachys schtschegleevii, Stachys byzantine, and Stachys lavandulifolia - was measured using Clevenger distillation system and water-essence solvent. The compounds present in the essence of each species was identified using GC and GC/MS techniques. Findings: The highest and lowest amount of substance m-Bis (m-phenoxyphenoxy) was observed in Stachys Inflate (87.91%) and Naphthalene (0.27%), respectively. The highest and lowest subtance present in Stachys schtschegleevii was phenol (59.16%) and octanne (1.15%), respectively. The highest and lowest subtance present in Stachys byzantina was phenol (68.97%) and octanne (0.54%), respectively. The highest and lowest subtance present in Stachys lavandulifolia was octanne (29.20%) and linalool (1.002%), respectively. Discussion and conclusion: The results of this study showed that significant changes in the type and amount of chemical substances present in the essensial of the plants under study in different regions indicated the effect of environmental and ecological factors on the quality of the substances comprising the essence of a given plant.
