چکیده


در این مطالعه ترکیبات تشکیل دهنده اسانس، اثرات آنتی اکسیدانی و میزان فنل و فلاونوئید آنغوزه در دو جمعیت ایرانی و افغانستانی مورد بررسی قرار گرفته است. شناسایی ترکیب های تشکیل دهنده اسانس توسط دستگاه GC-MS صورت گرفت. بررسی اثرات آنتی اکسیدانی با استفاده از روش‌های 2و2 دی فنیل 1-پیکریل هیدرازیل و بتاکاروتن - لینولئیک اسید انجام شد. محتوای ترکیبات فنلی و فلاونوئیدی نیز به ترتیب با استفاده از استانداردهای گالیک اسید و کوئرستین اندازه گیری شد. نتایج نشان داد که پروپنیل سک بوتیل دی­سولفید (72%/42)، استون دی متیل مرکاپتول(84%/14) و گاما ادیسمول (8.60%) فراوان ترین ترکیبات موجود در اسانس آنغوزه ایرانی است، پروپنیل سک بوتیل دی سولفید (61%/39)، استون و دی متیل مرکاپتول (25%/18)، و 8 اتیل پنتادی دکان (97%/17) فراوان ترین ترکیبات تشکیل دهنده اسانس آنغوزه افغانستانی بودند. میزان فعالیت آنتی اکسیدانی انغوزه ایرانی در روش DPPH قدرت بیشتری را نشان داد در حالی که در روش بتاکاروتن- لینولئیک اسید میزان فعالیت آنتی­اکسیدانی نمونه افغانستانی بیشتر بود. محتوای ترکیبات فنلی و فلاونوئیدی در جمعیت افغانستانی بیشتر از جمعیت ایرانی بود. در مجموع نتایج نشان داد که دو جمعیت مورد بررسی در این پژوهش از نظر نوع و درصد ترکیبات تشکیل دهنده اسانس، قدرت آنتی اکسیدانی و محتوای فنل و فلاونوئید دارای تفاوت هایی با هم هستند. این تفاوت‌ها احتمالاً ناشی از تفاوت در عوامل اکولوژیکی مانند زیستگاه های محل رویش این جمعیت ها و تاثیر این عوامل برفاکتورهای مطالعه شده است.

چکیده English

In this study, the essential oil composition, antioxidant activities, phenolic and flavonoid contents, and of metanolic extract of Iranian and Afghanestanian populations of Ferula assa-foetida were evaluated. Essential oils were analyzed by using GC and GC/MS, The antioxidant activity were measured by 2, 2-diphenyl-1-picrylhydrazyl and β-carotene/linoleic acid assay, also phenol and flavonoid content were measured by gallic acid and quercetin as standard compound. Result showed that propenyl sec butyl disulfide (42.72%), acetone, dimethyl mercaptole (14.84%) and gamma- eudesmol (8.6%) were the main compouned found in the Iranian population while; the Afghanestanian population were rich of propenyl sec butyl disulfide (39.61%), acetone, dimethyl mercaptole (18.25%) and 8-ethyl-pentathiadecane (18.97%). In DPPH and β-carotene/linoleic acid tests, Iranian and Afghanestanian populations have stronger antioxidant activity respectively, also, the results demonstrated that the Afghanestanian population have more phenolic and flavonoid contents than the Iranian population. Overall, the results showed that the two populations investigated in this research have differences in terms of the type and percentage of essential oil compounds, antioxidant activity and phenol and flavonoid content. These differences are probably caused by differences in ecological factors such as the habitats of these populations and the influence of these factors on the studied parameters.

Key words: propenyl sec-butyl disulfide, dimethyl mercaptol acetone, DPPH, β-carotene/linoleic acid
