| شناسه دیجیتال (DOR): 98.1000/1735-0905.1400.37.178.105.1.1576.1606 به‌منظور ارزیابی صفات کمّی و کیفی گیاه خوشاریزه عطری (Echinophora platyloba DC.) تحت تأثیر روش‌های مختلف خشک کردن تحقیقی در قالب طرح کامل تصادفی با 3 تکرار در سال 1398 انجام شد. تیمارهای آزمایش شامل گیاه تازه، خشک کردن گیاه در سایه و آفتاب، آون 45، 55 و 65 درجه سلسیوس، آون خلأ 45، 55 و 65 درجه سلسیوس، میکروویو 200، 400 و 600 وات بودند. به این منظور بخش هوایی گیاه در خرداد ماه از ارتفاعات شهرستان تویسرکان جمع‌آوری شد و تحت تأثیر روش‌های مختلف خشک کردن قرار گرفت. اسانس‌گیری به‌وسیله دستگاه کلونجر انجام شد و بعد اجزای اسانس به‌وسیله دستگاه گازکروماتوگرافی جرمی مشخص شدند. یافتههای این تحقیق نشان داد که روش‌های مختلف خشک کردن گیاه خوشاریزه عطری تأثیر معنی‌داری بر درصد اسانس و تمامی اجزای اسانس داشت و روش میکروویو 400 وات دارای بیشترین میزان بازده اسانس بود، ولی روش مناسبی برای حفظ ترکیب‌های مؤثره در این گیاه نبود. روش خشک کردن در سایه با وجود طولانی بودن مدت زمان خشک کردن، مناسبترین روش در حفظ ترکیب‌های شیمیایی اسانس در گیاه خوشاریزه عطری بود. دامنه تغییرات درصد اسانس در این تحقیق بین 0.39-0.06% بود. طبق نتایج بدست آمده دامنه تغییرات عمده اسانس گیاه خوشاریزه عطری ازجمله ترانس بتا-اوسیمن 57.52-34.16%، آلفا-فلاندرن 16.52-8.87%، سیس اوسیمن 4.57-1.69%، بتا-فلاندرن 9.24-2.08%، پی‌سیمن 5.05-1.53%، بتا-پینن 1.94-0.73%، آلفا-پینن 5.15-1.83%، ولوتون 3.78-0.39%، ترانس کاروئول 1.92-0.38%، لینالول 3.57-0.72% و دی جرماکرن 4.91-1.67% بود. | ||

| To evaluate the quantitative and qualitative characteristics of Echinophora platyloba DC. under the influence of different drying methods, an experiment was conducted in a completely randomized design with 12 treatments and three replications in 2019. The experimental treatments included fresh plant, drying the plant in the shade and sun, drying the plant with an oven at three temperatures of 45, 55, and 65 °C, drying the plant with a vacuum oven at three temperatures of 45, 55, and 65 °C, and drying the plant with a microwave at three powers of 200, 400, and 600 W. The aerial parts of the plant was collected from the heights of Tuyserkan city in Hamedan province in June and was affected by the different drying methods. The essential oil was extracted by Clevenger apparatus and then its components were identified by GC-MS. The findings of this study showed that the different methods of plant drying had a significant effect on the percentage and all the components of essential oil. The microwave drying method at 400 W, despite not being suitable for preserving the secondary metabolites of the plant, caused the highest essential oil content. The shade-drying method, despite the long drying time, was the most suitable method for preserving the essential oil composition in E. platyloba. The essential oil percentage in this study ranged from 0.06% to 0.39% and the main essential oil constituents included trans-β-ocimene (34.16-57.52%), α-phellandrene (8.87-16.52%), cis-ocimene (1.69-4.57%), b-phellandrene (2.08-9.24%), p < /em>-cymene (1.53-5.05%), β-pinene (0.73-1.94%), a-pinene (1.83-5.15%), veloutone (0.39-3.78%), trans-carveol (0.38-1.92%), linalool (0.72-3.57%), and germacrene-D (1.67-4.91%). | ||
