    In this research we investigated the role of Si in improving salt tolerance in the medicinal plant Borago officinalis L. Borago was pretreated with 0, 0.5 and 1.5 mM Si (as sodium silicate, Na2(Si O2)3) and then treated with four levels of NaCl, namely, 0, 60, 90 and 120 mM NaCl. Then the effects of silicon and NaCl were observed on some physiological and biochemical parameters such as lipid peroxidation malondealdehyde (MDA) and other aldehydes, proline, protein and carbohydrate contents. NaCl significantly increased MDA, other aldehydes and proline contents. Addition of 0.5 mM Si decreased the level of reducing sugars in salt‐stressed plants in the leaves. But in plants pretreated with Si and then exposed to NaCl, MDA, other aldehydes contents and carbohydrate in the roots decreased significantly. Protein content on the other hand, increased significantly (P

    Charlock (Sinapis arvensis L.) is a serious weed of agriculture, especially in spring sown crops. Genus Glaucium Mill. belongs to Papaveraceae and members of this genus have several alkaloids in laticiferes. The present research focuses on effects of aquatic extract of Glaucium oxylobum, G. elegans and G. grandiflorum on many physiological factors of Charlock. Laboratory studies were conducted to determine the seed germination and growth factors in charlock as affected by water soluble constituents of three species of Glaucium. Aboveground tissues of these plants were collected during flowering stage and dried. Five concentrations of aqueous extracts were used: full‐ strength (33.3 g lit‐1), three‐fourth ‐ strength (25 g lit‐1), half‐ strength (16.7 g lit‐1) and quarter‐ strength (8.3 g lit 1) and blank (0 g lit‐1). Charlock seeds were placed in petri dishes containing the Glaucium extracts, or distilled water (control). Seed germination percent was calculated after ten days. In general seed germination of Charlock declined progressively with increasing concentration of the Glaucium extracts. According to our results, with increasing concentration of aqueous extract, Charlock growth factors such as root and shoot length, root and shoot fresh and dry weight were inhibited.

    An ethnopharmacological survey was carried out among the most well‐known Turkmen indigenous herbal practitioners in northeast of Golestan Province (Maraveh Tappeh), north of Iran, in order to evaluate the therapeutic potential of local plants used by the rural Turkmen people to prevent or treat illnesses. Nineteen local practitioners of Turkmen traditional medicine, ages 55 to 65, were interviewed using a questionnaire. The survey revealed that 45 plant species most of them belonging to Asteraceae, Lamiaceae, Apiaceae and Fabaceae family are used as traditional medicine in the region for treatment of various diseases. Among these plants, 20 species have been used mostly as anti‐inflammation, anti‐infection, diuretic, sedative, carminative, vermifuge, laxative and tonic to treat cough, cold, skin wounds, cramp, infections, digestive disorders, cardiovascular disorders, stomachache, menstrual problem, UTI (urinary tract infection), IBS (irritable bowel syndrome), diabetes, migraine, headache, hemorrhage and circulatory disorders. The paper also reports features such as local name, life form, the current diseases, plant species used for the treatment, their medicinal effects, the plant part used, plant status, number of citation, and methods of their preparation and administration.

    Bipod nettle Utrica dioica L has therapeutic properties in treatment of human chronic diseases such as anemia, joints pain and skin diseases. In this research the major components of extracts in different parts of plant (root, stem and leaf) were identified by gas chromatography (GC) apparatus. Twenty compounds were identified, the most important of which were Neophytadiene 25.21%), Phtaleic acid (8.15%), Dibutyl phtaleate (7.37%), Bis (2‐ethyl hexyl) maleate (6.32%) and 1,2 benzenocli carboxylic acid (7.62%). The study revealed that the amount of these compounds in leaf was greater than in other parts of plant. Thus to extract the antibacterial compounds in Urtica dioica L., it is recommended to use leafs.
