Abstract
Blessed thistle (Cnicus benedictus L.) is an abundant resource with huge phytochemical and agronomic potentials. Their variation in response to agronomic techniques needs to be explored. Field studies were laid out to assess plant density and nitrogen fertilizer (N) effects on blessed thistle plant height, branches number (m-2), vegetative variables and RGR (relative growth rate), CGR (crop growth rate), LAR (leaf area ratio), NAR (net assimilation rate), as growth variables along with blessed thistle essential oil content, yield and compositions in two growing seasons. A three replicated factorial combination of plant densities (5, 10, 15, 20 and 25 plants m-2) and N levels (0, 50, 100 and 150 kg ha-1) in a randomized complete-block design

Abstract
Certain post-harvest processes of medicinal and aromatic crops (MACs) such as washing, drying, cutting and milling, decontamination, packaging, and warehousing are widely applied in the industry. However, the effects of some of them on the active ingredients have been less thoroughly studied. Changes in the essential oil (EO) content and composition of hyssop leaves were studied under cold plasma treatments (voltage values of 17, 20 and 23 kV for 1, 5 and 10 minutes), using different packaging methods (packaged with air, nitrogen, and under vacuum) and storage duration (0, 3 and 6 months). All samples were hydro-distilled for EO content evaluation and EO composition was determined by gas chromatography and gas chromatography–mass spec

Genetic Variation and Structure in Natural Populations of a Medicinal Vegetable, Satureja bachtiarica, Inferred from Microsatellite Markers Developed Using Next-Generation?…
Satureja bachtiarica Bunge (Lamiaceae) is a medicinal plant native to Iran which is widely used in traditional medicine, as a spice and as a vegetable. Understanding the patterns of genetic variation and structure of natural populations of the plant will be crucial for breeding and management purposes. However, until now, there has been no molecular tool with codominance inheritance available for studying genetic variation in this plant. In this study, we developed microsatellite markers for S. bachtiarica using a next-generation sequencing technique, and applied these markers to quantify the genetic variation and structure of natural populations. Sixty individuals collected from five natural populations were tested with 15 markers, 11 of w

Abstract
Developing alternative oilseed crops with acceptable seed yield and biomass production in low-yielding environments could be a part of sustainable agriculture management strategies. Field experiments were conducted in a semiarid region of Iran in 2013 and 2014 to determine the effects of N fertilizer rates and plant densities on growth, seed yield and quality of blessed thistle (Cnicus benedictus L.) under low yielding conditions. Randomized complete-block design with factorial arrangement of treatments was used in three replicates. Treatments consisted of four N rates (0, 50, 100, and 150 kg N ha–1) combined with five plant densities (5, 10, 15, 20, and 25 plants m–2). According to quadratic functions, the maximum seed yield (913 kg ha
Extracts of nine agricultural wastes prepared with five different solvents were assessed for their potential nematicidal activity against three nematode species, Aphelenchus avenae, Meloidogyne incognita and Pratylenchus neglectus, in in vitro condition. The 50% v/v hydro-ethanolic extracts showed the highest performance for two tested plant wastes of cabbage leaves and faba bean pods. These two extracts were tested on nematodes in three different concentrations. The highest in vitro nematistatic activity was recorded for 3000 and 1500 ppm of cabbage leaf extracts by 100% paralysis of all three nematode species after 48 h, and the highest nematicidal activity was recorded for the above-mentioned extract by 25-100% mortality depending on nem
The LC-MS analysis of the MeOH extract of the aerial parts of Pergularia tomentosa led to the isolation of 23 compounds, of which the structures were elucidated unambiguously by NMR spectroscopic data analysis. Three new doubly linked cardenolides (4, 13, 14) along with several known cardenolides (1–3, 5, 7, 8, 15–23) and flavonol glycosides (6, 9–12) were identified. LC-HRESIMS analysis, in the negative-ionization mode, showed the absence of flavonoids in a methanol extract of the roots of P. tomentosa. On the basis of the antiproliferative activity reported for cardenolides, the isolated compounds were tested for their ability to decrease the cell viability of five different human cancer cell lines, PC3, HeLa, Calu-1, MCF-7, and U25
Coltsfoot (Tussilago farfara L.) from Asteraceae family is a perennial plant. Its flowers and leaves have been used traditionally for the treatment of cough, bronchitis and phlegm disorders. For this study the leaves and flowers of T. farfara were collected from seven major regions of Iran including Firoozkooh, Nur, Deylaman, Kaleybar, Namin, Damavand and Pol-e-Zangholeh. The leaves and flowers were prepared for phytochemical studies. Essential oils of leaves and flowers were obtained and their compositions were identified and quantified with GC/MS and GC, respectively. The major compounds in leaves essential oil were 14-Hydroxy-Z-caryophyllene, α-Cadinol, 4,4-Dimethyl tetracyclo[5.2.1.02,6.03,5]decane, Humulene epoxide II and (E)-Nerolido
Pergularia tomentosa (Asclepiadaceae) is a milkweed tropical plant used in traditional medicine for the treatment of several diseases such as bronchitis, constipation and skin diseases [1]-[3]. Previously we reported the occurrence of cardiac glycosides with trans fused A/B rings of the steroidal skeleton and with a single sugar, linked to the 2α-and 3β-positions of the aglycone by hemiketal and acetal functions respectively [1],[3],[4]. Isolated cardenolides inhibited cell viability of PC3, Hela, Calu-1, MCF-7, and U251MG cell lines exhibiting IC 50 values ranging from 0.2 to 8.0 μM [4]. Herein, the ability of the isolated compounds to inhibit cell viability of Hepg2 (liver hepatocellular carcinoma) cell line has been evaluated. Of all
In order to investigate the effects of infrared radiation intensity and air velocity on some of the qualitative characteristics of hyssop (Hyssopus officinalis L.) during the drying process, a factorial experiment was conducted in a completely randomized design with three replications. The infrared radiation intensity was investigated at three levels of 0. 2, 0. 3 and 0. 5 W/cm2 and the air flow velocity at 0. 5, 1 and 1. 5 m/s, and traits such as color parameters, essential oil content and composition were evaluated. The results showed a significant effect of treatments on all studied traits. In the radiation intensity of 0. 3 W/cm2, with increasing air flow velocity, there was a significant increase in the desired color parameters such as
