چکیده This review explores the therapeutic potential of polyunsaturated fatty acids (PUFAs) derived from medicinal plants. PUFAs, including omega-3 and omega-6 fatty acids, play critical roles in human health and are essential for various physiological functions. While marine sources are known for their high content of omega-3 PUFAs, medicinal plants also serve as valuable sources of omega-6 important fatty acids. PUFAs derived from medicinal plants exhibit a wide range of therapeutic properties, including anti-inflammatory, antioxidant, neuroprotective, cardiovascular protective, and anticancer effects. This review summarizes the classification and sources of PUFAs, and discusses the extraction of PUFAs from medicinal plants. Specific medicinal plants rich in PUFAs are highlighted, along with their potential health benefits. Understanding the role of PUFAs in promoting human well-being opens avenues for the development of natural interventions and therapeutic approaches. By exploring the rich composition of PUFAs in medicinal plants, we can harness their potential in preventive healthcare and complement existing treatments. Overall, this review provides valuable insights into the medicinal properties of PUFAs derived from plants.

چکیده خشکی به عنوان یک تنش چند بعدی، اثرات مخرب و نامطلوب مختلفی بر گیاهان دارد و بسیاری از خصوصیات مورفولوژیکی و فرآیندهای فیزیولوژیکی، بیوشیمیایی و تغذیه ای مرتبط با رشد و نمو گیاه را تحت تأثیر قرار می دهد. این تنش باعث تولید گونه های فعال اکسیژن و آسیب به غشای سلولی می شود. در دستگاه فتوسنتزی برگ، مهار انتقال الکترون باعث کاهش رنگدانه های اصلی فتوسنتزی و تجمع پروتئین می شود. پاسخ گیاه گندم به تنش کم‌آبی مکانیسم‌های زیادی دارد که شامل تغییرات سلولی – مولکولی و انتقال آن به سایر فعالیت‌های متابولیکی و تأثیر آن بر مورفولوژی و فنولوژی گیاه می‌شود.بنابراین، هدف کلی این تحقیق بررسی اثر متقابل نانوذرات اکسید آهن (25 نانومتر) با دو نوع نانوذرات روی (25 و 50 نانومتر) با غلظت 50 میلی‌گرم در لیتر بر مقاومت بیشتر گیاهان گندم (ارگ) بود. رقم) و بهبود رشد آن در شرایط تنش خشکی. بدین ترتیب گیاهان گندم تحت تیمار تنش خشکی شامل دو سطح شاهد و 7 روز کم آبی قرار گرفتند. پس از اعمال تیمارهای خشکی و نانوذرات روی گیاهان، برخی از پارامترهای رشد و رنگدانه در ساقه، ریشه و برگ اندازه‌گیری شد تا تأثیر نانوذرات روی و آهن به طور جداگانه و متقابل بر مقاومت گیاهان به تنش خشکی بررسی شود.

چکیده Drought stress affects many morphological characteristics and biochemical processes related to plant growth and development. In this sense, drought, as a multidimensional stress, has various destructive effects on plants. By inhibiting the transfer of electrons, this stress creates a secondary stress in the production of reactive oxygen species, causing double damage to the cell membrane, photosynthetic pigments, and other physiological parameters. Today, the use of metal nanoparticles such as zinc and iron in improving activities and dealing with plant stresses can create beneficial effects in plant and agricultural biotechnology. The treatments include drought stress at two levels (drought stress and no drought stress) as the main factor and three levels of iron, zinc separately and integrative of iron and zinc nanoparticles. The results showed that all investigated traits were affected by drought stress conditions, so that under drought stress the fresh and dry weight. Chlorophyll a and b, decreased and the usage of iron and zinc nanoparticles reduced the effects of drought stress in mentioned growth parameters in tomato plants. Therefore, the application of the above nanoparticles can be very effective in improving the growth of tomato plants, especially in dry areas.

چکیده The agricultural sector in developing countries can be the main engine of economic growth and development, but it is always affected by various biotic and abiotic stresses that cause waste of resources. One of the most important of them are pests. Mankind has always been trying to fight against these factors. One of the solutions is the use of chemical and synthetic pesticides, whose negative and destructive effects on human health and the environment are always discussed today. Some plants have secondary metabolites that have pesticidal effects and are very efficient with different effects on insects. Extracts of plant or whole plants have been used for centuries in various cases including pest control, and They are known all over the world. Bioactive plant compounds such as glycosides, alkaloids, flavonoids have pesticidal effects that do not affect natural enemies and provide food products free of toxic residues. In addition, no negative effects of these compounds on human health have been reported so far. Today nearly 2500 plants with insecticidal properties are known, but unfortunately only a few of them have been properly evaluated. Furthermore, commercial biopesticides are not widely used in conventional crop production but are recognized by organic crop producers in industrialized countries

چکیده Lawsonia inermis is utilized in the cosmetics industry and traditional medicine for the treatment of various ailments. Understanding the chemical and genetic diversity of this plant is essential for breeding purposes. This research investigated the chemical and genetic diversity of 12 distinct populations of Lawsonia inermis from different areas of Kerman province through the use of HPLC and ISSR markers. HPLC was employed to quantify the Lawson compound in the 12 populations, while three ISSR primers were utilized to evaluate genetic diversity. The findings showed notable diversity in Lawson content among samples collected from Jiroft, Shahdad, and Ghale Ganj, with the J5 sample (from Jiroft) displaying the highest value. Furthermore, the ISSR marker demonstrated that all populations could be grouped into three categories, with samples from the same region not necessarily clustering together. Although the marker could not differentiate populations based on Lawson content, it effectively distinguished them based on genetic diversity.
