Abstract

 
Willow herb (Epilobium sp.) is a medicinal plant that is used for various purposes in the traditional medicine and food industries. In this research, an attempt was made to assess morphological and phytochemical variations in eight Epilobium species (E. hirsutum, E. Parviflorum, E. roseum, E. algidum, E. anatolicum, E. confusum, E. frigidum, and E. lanceolatum). The species were collected from natural habitats during the flowering period. Analysis of variance showed a significant variation among the studied species for measured morphological and phytochemical traits. Total phenolic content varied from 194.64 ± 1.17 to 309.10 ± 5.59 mg g-1 DW, total flavonoids ranged from 39.03 ±0.21 to 56.14 ±0.67 mg g-1 DW, and antioxidant activity differed from 43.03 ± 2.20 to 101.36 ± 3.68 mg g-1 DW. The results showed that E. frigidum is the richest source of natural antioxidants among the studied species, and also has the highest seed and leaf lengths. Antioxidant activity was significantly correlated with bioclimatic variables. However, the dendrogram based on morphological traits was relatively different from that based on all phytochemical variables. In conclusion, the remarkable variation among species for the morphological and phytochemical traits may be exploited in the breeding programs of the genus Epilobium.

Abstract [Persian]

بید علفی یک گیاه دارویی است که برای اهداف متنوع در طب سنتی و صنایع غذایی استفاده می­ شود. در این تحقیق تلاش شده است که تنوع مورفولوژیکی و شیمیایی در هشت گونه گیاه اپیلوبیوم بررسی شود. گونه­ های گیاهی از رویشگاه طبیعی در طول دروره گلدهی جمع آوری شدند. تجزیه واریانس تنوع مورفولوژیکی معنی­ داری را میان گونه­ های مورد مطالعه برای صفات مرفولوژیکی و فیتوشیمیایی نشان داد. فنل کل از 1.17 ± 194.64 تا 5.59 ± 309.1 mg g-1 DW، فلاوونوئید کل از 0.21 ± 39.03 تا 0.67 ± 56.14 mg g-1 DW و فعالیت آنتی اکسیدانی از 2.20 ± 43.03 تا  3.68 ± 101.36 mg g-1 DW  نوسان داشت. از یافته­ های ما استنتاج شد که E. frigidum دارای غنی ترین منبع آنتی اکسیدانی در بین گونه ­های مورد مطاعه و همچنین ببشترین طول بذر و طول برگ است. فعالیت آنتی اکسیدانی با داده­ های اقلیمی ارتباط معنی ­دار داشت. دندروگرام بر اساس صفات مورفولوژیکی با دندروگرام بر اساس متغیر‌های فیتوشیمیایی نسبتا متفاوت بود به طور کلی، تنوع زیاد بین گونه‌ها برای صفات مورفولوژیکی و فیتوشیمیایی می­ تواند در برنامه‌های اصلاحی جنس Epilobium مورد بهره‌برداری قرار گیرد.
