مقایسه ترکیبات فیتوشیمیایی اسانس در اکوتیپ‌های Teucrium polium subsp. polium دراستان فارس
Authors
Abstract:
مریم نخودی گیاهی است بومی ایران که در طب سنتی مورد استفاده قرار می گیرد. پژوهشی به منظور مقایسه کمیت و کیفیت مواد موثره اسانس Teucrium polium subsp. Polium در هفت منطقه مختلف استان فارس با محدوده ارتفاعی 800 تا 2500 به اجرادرآمد. سرشاخه های گلدار و هوایی نمونه ها بعد از خشک شدن، به روش تقطیر با آب (طرح کلونجر) اسانس گیری و سپس ترکیبات اسانس با دستگاه‌های GC وMS/GC شناسایی شدند. نتایج نشان داد مهمترین ترکیبات اسانس در رویشگاههای مختلف متغیر بوده و به ترتیب در این هفت منطقه عبارتند از: ژرماکرن-دی (7/6 – 6/22 دررصد)، بی-سیکلوژرماکرن (4/4 – 1/15 درصد)،آلفا-پینن(8/0 – 6/16 درصد)، بتا-پینن (8/0 – 2/9 درصد)، میریسن (7/1 – 5/9 درصد) وای-کاریوفیلن (2/4 – 9/13 درصد). مقایسه ترکیبات عمده اسانس هانشان داد که اکوتیپ هایی که از مناطقی با ارتفاع بالاتر جمع آوری شده بودند، نسبت سزکوئی ترپن های اسانس بیشتر از مونوترپن های آن بود. نتایج حاصل از آنالیز داده های مربوط به ترکیبات اصلی اسانس، با نرم افزار Minitab به تشخیص 3 گروه متمایز منجر شد که نشان دهنده وجود تنوع فیتوشیمیایی درون گونه‌ای در این گیاه است. .

Recently, there is growing interest in finding naturally occurring antioxidants for use in foods or medicinal materials to replace synthetic antioxidants, which are being restricted due to their carcinogenicity [1]. Antioxidants are secondary constituents or metabolites found naturally in plants. They are mainly phenolics serving in plant defense mechanisms to counteract reactive oxygen species...

| May 2014 | 478 plants have been shown to produce oxidative stress and toxicity.[15-17] This toxicity inclines to be more common among certain patients and in specifi c clinical conditions. Thus, knowledge about successful prevention or amelioration of a medicinal drug requires information about pathogenic mechanisms of kidney damage and related risk factors.[1,8,18,19] In this regard, to be e...

The term cancer has been concomitant with despair, agony, and dreadful death. Like many other diseases, herbal therapy has been used to prevent or suppress cancer. The present study investigated the capability of the decoction of Teucrium polium L. from Lamiaceae family to protect liver cells against hepatocellular carcinoma in carcinogenesis-induced animal model. After 28 weeks of treatment wi...

Teucrium (Lamiaceae) is a large and polymorphic genus distributed mainly in Europe, North Africa and in the temperate parts of Asia. In this study, the anatomical features of the leaf and stem of Teucrium polium are investigated. Teucrium has 19 taxa in Iran, which mainly grow in the Irano-Turanian region between 700 and 2000 m above sea level. T. polium belonging to sect. Polium, is a perennia...
full textIdioblastic Mucilage Cells in Teucrium Polium Leaf. Anatomy and Histochemistry
In the mesophyll of Teucrium polium L. leaves, isolated or grouped idioblastic secretory cells occur in contact with the distal (adaxial) vessel elements of the vascular bundles. They appear to originate from one or more bundle sheath cells and their intracellular space is entirely occupied by the secretory material. The latter has a glycoproteinaceous constitution (mucilage), as histochemical ...
