Tarragon (Artemisia dracunculus L.) has antioxidant, anti-diabetic, anti-bacterial and anti-inflammatory proper-ties. The aim of this study was to evaluate the effect of tarragon hydro-alcoholic extract on anxiety and depression in male rats exposed to chronic restraint stress. Forty eight male rats were randomly divided into six groups including 1) control, 2) stress, 3) tarragon 100, 4) tarragon 500, 5) stress-tarragon 100 and 6) stress-tarragon 500. Groups 2, 5, and 6 were placed in restrainer for 21 consecutive days, 6 hours a day. Groups 3, 4, 5, and 6 were gavaged with tarragon extract of different do-ses (100 and 500mg/kg). At the end of this 21-day period, anxiety and depression were evaluated by elevated plus maze and forced swimming test. Data analysis was performed using one-way ANOVA, p<0.05 being considered significant. The pe-rcentages of open arm entry and time spent in open arm increased significantly in tarragon-stress groups compared with st-ress group (p<0.05). Tarragon extract decreased significantly the immobility time in rats exposed to stress in forced swim-ming test (p<0.01). The results suggested that hydro-alcoholic extract of Artemisia dracunculus L. reduced the anxiety and depression in rats exposed to chronic immobilization stress, probably due to its anti-oxidant compounds

The availability of iron for roots has been demonstrated as a critical factor in plant production. The addition of synthetic iron chelates to soil is a common practice in agriculture, which is not economically beneficial. Besides, chemical iron fertilizers cause many problems such as food contamination and environmental pollution. Development of natural Ferrioxamine B as an efficient and safe iron source may be the best strategy to overcome plant iron deficiency and prevention of synthetic agent pollution. The present study investigates the ability of a hydroxamate type siderophores (Ferrioxamine B) as a substitute Fe source during tissue culture of chickpea plants. For this purpose, embryo axes from chickpea seeds were surface sterilized and cultured in 1/2MS and MS culture media including 3% sucrose and 0.8% agar with Ferrioxamine B or Fe–EDTA. The root and shoot length, shoot and root dry weight, total fresh and dry weight, as well as chlorophylls a and b were analysed. Results indicated that Ferrioxamine B did not increase chlorophylls a and b in comparison with Fe-EDTA. However, rooting (22%), total dry weight (38%) and root (75%) and shoot (22%) dry weight significantly (p≤0.05) increased in MS containing Ferrioxamine B in comparison with Fe-EDTA. Consequently, Ferrioxamine B is introduced as a cost-effective and applicable Fe source to favour iron deficiency in vitro.
