        Onion is a medicinal plant which have many uses in traditional medicine. It is a valuable crop since ancient times and it ranks second after tomato among cultivated vegetables in the world. Also, onion has great importance in the diet of Iranian people. In this study effect of different nitrogen levels (56, 112, 168 and 224 mg.L-1) on antimicrobial activity and some physiological characteristics of bulb extracts were studied.The highest and lowest amounts of inhibitory efficacy of methanol extract of onion bulbs at concentration of 0.30 mg.L-1 against Pseudomonas aeruginosa and Bacillus subtilis, were observed. According to the results, different levels of nitrogen had a positive effect on the antimicrobial properties onion bulb extract. With increased nitrogen concentration in nutrient solution, antimicrobial activity onion bulb extracts increased. With the increase in nitrogen concentration in nutrient solution content antioxidant activity, total phenol, total flavonoids, and ascorbic acid were increased. Increasing the concentration of antioxidant compounds was associated with increased antimicrobial activity of onion bulb extract. In recent years, the consumption of onion has increased due to its flavor and health benefits. The beneficial properties of onion are mainly related to its high content of sulfur compounds and flavonoids, and the role of these compounds as antioxidants, anti-microbial and anti-cancer have been proven. Nitrogen was effective on the inhibitory effect of bulb methanol extract, which could be due to the effect of nitrogen on the metabolism of sulfur compounds and flavonoids in bulb. Manuscript profile

        Antioxidants metabolites which are protect the body against damage caused by free radical activity. Phenolic compounds are secondary metabolites in medicinal plants, which have a high antioxidant power. Karela (Momordica charantia L.) is an herb belonging to Cucurbitaceae family, consisted of phenolic compounds which can act as antioxidant. The present study was conducted to investigate the effect of different solvents (methanol, acetone, ethyl acetate, hexane and chloroform) on total phenolic, flavonoids content and antioxidant activities of Karela in Sistan region in 2016. Different extracts of plant parts ( Root, leaves and fruit) were obtained by different solvents by maceration method. Total phenolic and flavonoid contents were measured by Folin–Ciocalteu and Aluminum chloride methods, respectively. Antioxidant activity of extracts were determined by using Diphenyl Picryl hydrazyl (DPPH), Hydrogen peroxide (H2O2) and Ferric Reducing Antioxidant Power (FRAP) assays. The results were showed that the highest phenolic content was observed in fruit and leaf methanol extract (36.96±1.33 and 33.01±3.03 mg gallic acid/g DW respectively) and the least amount of phenol was extracted by ethyl acetate, hexane and chloroform which was less than 1 mg/g DW. The highest flavonoid content was observed in leaf acetone and methanol extract (10.95±1/97 and 10.03±2.2 mg quercitin/g DW respectively). Fruit methanol extract showed higher antioxidant activity than other extracts in three methods. Based on results of this research, Karela fruit can be suggested as useful source of natural antioxidants Manuscript profile

        This study was investigated the relationship between the number of phenols, flavonoids, antioxidant, and antimicrobial properties of extracts of some medicinal plants. Aerial parts of plants in blooming of Artemisia annua (from Saravan City), Thymus vulgaris (from the Medicinal plants farm of Zabol University), Matricaria chamomill (from Farashband City), Salvia officinalis (from the Medicinal plants farm of Zabol University) and Fruit of Pistacia atlantica (from Saravan City) were collected from farms and habitats of Sistan and Baloochestan and Fars province in 2016. The plant extracts were obtained by maceration method, phenolic and flavonoid contents were determined by Folin-Ciocaltiu and Aluminum Chloride colorimetric, antioxidant activities were studied by method DPPH (2,2-diphenyl-1-picrylhydrazyl) and then antimicrobial activities were estimated by Disk-Diffusion method against two bacteria Staphylococcus aureus and Escherichia coli. The plant extract of Artemisia annua and Thymus vulgaris respectively had maximum total phenolic (22.36 mg/g DW) and flavonoid contents(142.59 mg/g DW) and antioxidant activity, (72.01 µg/ml and 70.75 µg/ml) and antibacterial activity against Staphylococcus aureus and Escherichia coli respectively with inhibition zone (15.1 and 16.8 mm ) was the most sensitive bacteria to plant extracts. Generally, the methanolic extract of the plants demonstrated different levels of antioxidant activity; in addition, the best antioxidant activity was related to Artemisia. Hence, it can be argued that these extracts of herb, instead of chemical drugs, can be used to treat infections. Furthermore, before using them all their side effects should be carefully investigated in in vitro accompanied by in vivo studies. Manuscript profile

        Artichoke (Cynara scolymus L.) is a perennial plant that belongs to the Asteraceae family. It has a special place in the pharmaceutical and food industries all over the world. In order to evaluate some phytochemical characteristics of artichoke leaves at different growth stages, an experiment was conducted by using a randomized complete blocks design (RCBD) with three replications in Isfahan Agricultural and Natural Resources center during two consecutive years (2014-2015 and 2015-2016). In the second year, the leaves were collected at three growth stages: vegetative, heading and flowering in the second year. After harvesting, some quality factors such as their total phenolic content (Folin–Ciocalteu method), total flavonoids (Colorimetric Method of Aluminum Chloride), chlorogenic acid content (HPLC method) and antioxidant activity (DPPH free radical scavenging activity and reducing power) were measured. The results showed that the phytochemical and antioxidant properties of artichoke leaves were different at the three growth stages. The highest amount of phenolic content (76.25 mg GAE g-1 DW), total flavonoid (1.28 mg QE g-1 DW), chlorogenic acid content (2.25 % DM), DPPH (92.34 %) and reducing power (2.16) of methanolic extract was observed in heading stage. There was a positive and significant correlation between total phenolic content and antioxidant activity. Also, the relationship between chlorogenic acid content and DPPH and reducing power was positive and significant. According to the results, the harvesting of artichoke leaves at the heading stage is better than other growth stages due to their favorable characteristics. Manuscript profile

        Proper application of N fertilizer and its optimization in plants is definitely important. To study the effect of different level of nitrogen fertilizer on some morphological and phytochemical traits of artichoke, an experiment was conducted in a randomized complete block design with three replications in field conditions during two consecutive years in Isfahan, Iran. Nitrogen fertilizer was applied in 100, 150, and 200 kg/ha net nitrogen from urea source. Morphological traits including stem height, number of leaves per plant and number of capitols per plant and phytochemical traits such as total phenol, total flavonoid and antioxidant activity were measured. Increasing of urea fertilizer rate from 0 to 200 kg/ha increased stem height, number of leaves and capitols per plant, but decreased total phenol and flavonoid and antioxidant activity. Although nitrogen is an essential element for growth and development of artichoke plant, the consumption of high levels of nitrogen fertilizer has negative effect on qualitative traits. Also, considering chemical fertilizers hazard in environment, it is recommended to use 100 kg/ ha N to achieve optimal yield in artichoke. Manuscript profile
