Due to the ease of application, abundance and lack of significant side effects medicinal plants and their derivatives are used for poultry as effective additives. This experiment was conducted to evaluate the effects of different levels of nettle (Urtica dioica L.), pennyroyal (Mentha pulegium L.) and ziziphora (Ziziphora tenuior L.) on performance, carcass traits, blood hematological and biochemical parameters of broilers. The experiment was performed in a completely randomized design including 324 broilers (Ross 308) with 9 treatments and 3 replications (each replication included 12 hens) from age 1 to 42 days. Experimental groups included I) control group with no medicinal plants, and in other treatments the levels of medicinal plants in starter and grower periods were as II) 0.75% III) 0 and 0.75%, IV) 0.75% and 1.5%, V) 1.5% and 0.75%, VI) 0.75% and 1.5%, VII) 0 and 1.5%, VIII) 1.5% and 0, IX) 1.5% in both periods. The results showed that different levels of medicinal plants in starter and grower periods had significant effects on performance, carcass traits and hematological status of broilers (p < 0.05). According to the results, the highest daily weight gain (59.75g), the lowest feed conversion (1.90) the highest carcass percentage (74.04) and the highest percentage of gizzard (2.77) were observed in group 3, whereas the best level of white blood cells was observed in group 9, but there were no significant differences between experimental groups and control group in terms of performance and blood hematological parameters.

To study the effects of different sowing dates and different fertilizing methods (chemical &organic) on yield and amount of active substance of milk thistle (Silybum marianum (L.) Gaerate), a field experiment was done at Agricultural College of Shahid Chamran University during 2009-2010. Experimental design was split plot on RCBD with three replications. Main plot was sowing dates including (14Nov, 1 Dec and 15 Dec) and sub plot was different fertilization levels including: F1: control, F2:100% chemical fertilizer (100-120-150 kg/ha NPK, respectively), F3: %25 organic fertilizer + %75 chemical fertilizer (75-90-112.5 kg/ha NPK + 7.5 ton/ha animal manure), F4: %50 organic fertilizer + %50 chemical Fertilizer (50-60-75 kg/ha NPK + 15 ton/ha animal manure), F5: %75 organic Fertilizer + %25 chemical fertilizer (25-30-37.5 kg/ha NPK + 22.5 ton/ha animal manure), F6: %100 organic fertilizer (30 ton/ha animal manure). Results showed that sowing date had significant effect on the percentage of phenol and flavenoid and the amount of silymarin. Late sowing date (15 dec) decreased grain silymarin content, while the highest percentage of phenol and flavenoid was obtained at 15 Dec. Also, the highest percentage of flavenoid, flavenoid yield and silymarin yield were obtained at 100% chemical fertilizer and integrated fertilizer. In this regard, F2 treatment had no advantage compared to integrated fertilization levels. Also, the highest percentage and yield of phenol was obtained by integrated fertilizer methods. The highest silymarin content was related to F6, and the highest grain antioxidant activity was related to F4 and F6, respectively.

According to the dependence of Iran's economy on oil revenues, medicinal and aromatic plants could play an important role in domestic economy in addition to the great influence on non-oil exports. One of the mechanisms for production of such plants is development of their processing. Given the importance of this issue, the current study was performed to investigate the role of processing in development of cultivation of aromatic plants in Kashan. In general, this was a survey research in which data were collected by questionnaires and its validity was examined by Cronbach's alpha (higher than 0.7). The statistical population was growers of aromatic plants of which 250 persons were selected randomly. Data analysis was performed by descriptive and inferential statistics such as frequency, mean, coefficient of variation, and finally Mann-Whitney and T tes. The results showed that satisfaction of income resulted from aromatic plants and economic incentives were higher in the group of processors than that of the group of flower growers. It also became clear that processors allocated a higher percentage of the total land to cultivation of aromatic plants with more satisfaction from this job and more willing to continue in future.

The pomegranate seeds of four commercial varieties (Abanmahi (AB), Malas (MS), Pust Sefid (PS) and Shahvar (SH)) cultivated in Iran were evaluated in terms of quality properties including protein, oil, dietary fiber, mineral contents and fatty acid composition. Physicochemical properties and antioxidant activity of pomegranate seed oils (PSOs) also was determined. The oil antioxidant activity was measured by 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging capacity. Results showed that PS had the highest oil (16.9%) and crude fiber (42.4%), and nutritional value (460.7Kcal/100g) among the selected varieties. PS had the highest level of phosphorus (2766.3 mg/kg) and magnesium (2052.0mg/kg), while the highest calcium (675.3mg/kg) and potassium (3724.6mg/kg) were related to SH. The main fatty acid identified by gas chromatography was punicic acid ranged from 72.07% for SH to 73.31% for MS (pp2/kg), iodine (216.9-220.3g I2/100g) and saponification (179.3-182.5mg KOH/g) values. Also, refractive index at 25°C, viscosity and density of PSOs varied from 1.461-1.527, 0.036-0.063Pa.s and 0.9202-0.9311g/cm3, respectively. The oil obtained from MS showed the lowest level of ortho-diphenols (ODC) and DPPH radical scavenging capability. The relationship between percentage of remaining DPPH and ODC of PSOs also illustrated high correlation among all varieties (R2 = 0.98, p<0.01).

Cutaneous leishmaniasis is an endemic infectious disease known as a major health problem in many countries including Iran. Due to the lack of an effective vaccine, the disease is increasing in most parts of the world. Pentavalent antimony compounds as the first line drug against leishmaniasis has numerous side effects. Consequently, the need to introduce new, inexpensive and available drugs with fewer side effects to replace existing chemical compounds is fully felt. Herbal drugs could be a good alternative. In the present work, the effects of two native plants namely Artemisia sieberi Besser and Scrophularia striata Boiss. against Leishmania major were investigated under in vitro conditions. For this purpose, different concentrations of aqueous extracts of Artemisia and Scrophularia were investigated on the growth of promastigotes of Leishmania under in vitro conditions as well as growth of amastigote of Leishmania in mice macrophages. The results indicated that promastigotes in RPMI culture were killed completely under concentrations of 20% and 25% of Artemisia in the first day of the experiment; while the parasites were killed by Scrophularia at the concentration of 25% within three days. Reduction of the parasite growth in RPMI culture under three concentrations of Artemisia was significantly higher than that of Scrophularia. Concentrations of 20% of Artemisia in the second day and 25% of Scrophularia in the third day led to the complete elimination of amastigote of L. major in macrophages.

Licorice with common name of licorice pea from Leguminosae family has been noted for its many therapeutic effects. Using natural substances of plant origin has a long history in the treatment of various diseases. In this research, the effect of licorice on blood factors was examined. This study was performed on 50 mice. The samples were randomly divided into five groups (three treatment groups, control and the placebo group) and were kept under identical conditions. Hydro-alcoholic extracts of Licorice in doses of 50, 100, 150 mg/kg were injected by intraperitoneal (IP) within 20 days every other day. Physiological serum was injected to the control group. The main parameters included the RBC count, hemoglobin, hematocrit, platelet count, MCHC, MCH and MCV compared with control groups. Results showed that hemoglobin, platelet count, MCV and MCHC increased at all doses and MCH increased in 100 and 150 mg/kg dose, but the number of red blood cells decreased in doses of 100 and 150 mg/kg. No significant changes were observed in hematocrit. Results indicated a dose-dependent effect of the licorice on blood factors in mice.

The cultivation of medicinal plants such as the Lamiaceae family increasing throughout the world Significantly. Savory considers as an important species in this family which it’s important is due to carvacrol and thymol in essential oil. In order to investigate the effect of planting density and soil fertility on the physiological traits and antioxidant enzymes activity of savory under rainfed conditions, an experiment in the form of split plots with two factors, fertilizer as the main factor at three levels (control, 30 tons/ha cow manure and 10 tons/ha straw enriched with ammonium sulfate) and the sub-factor, plant density at three levels (2.67, 4 and 8 plants/m2) in the form of a complete block design A random experiment was conducted at Hamand Absard research station (Damavand) in 2017-18 and 2018-19. The analysis of variance showed a significant effect of planting density and organic fertilizers on the physiological traits of savory. The highest RWC (%87.67) and the lowest ELI (%47.19) were observed in the cow manure treatment with 30 tons/ha at a density of 2.67 plant/m2. As the density increased, total chlorophyll and RWC decreased and ELI and MDA and proline increased. Cow manure and straw increased total chlorophyll, proline and RWC and decreased ELI and MDA. The highest activity of CAT, peroxidase and SOD enzyme was obtained in the control treatment and 8 plant/m2 and the lowest in organic fertilizer treatment, 2.67 plant/m2. Increasing the activity of these enzymes to neutralize the reactive oxygen species produced due to water stress is known as a resistance mechanism in plants. Based on the results of this research, it can be said that savory has the ability to grow in rain-fed conditions and has the necessary potential to increase the antioxidant capacity in rainfed conditions.
