To evaluate the effect of seed treatment with gamma rays and nitrogen application on yield and nitrogen use efficiency for protein production in Chamomilla recutita L. leaves, a factorial experiment was conducted based on randomized complete blocks design with three replications. Treatments were gamma rays from Cobalt-60 source on chamomile seeds cv. Bodegold (0, 4, 8, 12, 16, and 20 Gray) and different levels of nitrogen (0, 50, 100, and 150 kg/ha). Results showed the significant interaction effect of gamma and nitrogen on the leaf yield, biomass and protein, harvest index of protein, and nitrogen use efficiency for leaf and protein production, the yield of dried flower and essential oil. But gamma irradiation and nitrogen had no significant effect on leaf protein and essential oil percentage. The highest yield of leaf (4194 kg/ha) and biomass (19996 kg/ha) were obtained at 8 GRAY of gamma rays with 100 and 150kg/ha of nitrogen application, respectively. However, the highest yield of protein (571kg/ha) was obtained from 20 GRAY of gamma rays and 0 kg/ha of nitrogen and the lowest yield (151kg/ha) was obtained from 0 GRAY and 50kg/ha of nitrogen. The highest value of nitrogen use efficiency for leaf (67.39) and protein (9.30) production was related to the plants grown from seeds and treated by 16 GRAY of gamma and 50kg/ha nitrogen. The lowest nitrogen use efficiency for leaf (13.94) and protein (1.42) production were observed at 16 GRAY and 150kg/ha nitrogen. The highest yield of dried flower in 0, 4, 8, 12, 16 and 20 GRAY were obtained at 150, 100, 0, 150, 100 and 100 kg/ha of nitrogen application, respectively. Generally, irradiations over the 12 GRAY resulted in reducing the nitrogen application for protein production.

In order to study the effect of sowing date and harvest frequency on flower yield, essential oil percent and composition of chamomile (Matricaria recutita L.) CV. Presov, prepared from Slovakia, an experiment was conducted. The experiment was split-plot method based on randomized complete block design (RCBD) with three replications. Main plots consisted of three sowing dates (6th Nov, 5th Mar, and 4th Apr) and sub-plots included three harvest frequencies (first, second and third). Evaluated traits were dry flower yield, essential oil percentage and yield, yield of b-farnesene, a-bisabolol oxide B, a-bisabolol, chamazulene, a-bisabolol oxide A. The results showed that sowing date, harvest frequency and their interaction had significant effect on these parameters. Based on the results, the most dry flower yield (40 g/m2) was obtained from the second harvest of 6th November. Also the highest essential oil content (0.72 percent w/w), essential oil yield (0.26 g/m2) and a-bisabolol yield (0.2375 g/m2) were obtained from the second harvest of March and the most chamazulene yield (0.0473 g/m2) was obtained from the third harvest of March that it had a little difference with second harvest. According to the results, the best chamomile quality was attained in second harvest of March sowing date in Mashhad condition.

In order to investigate the effect of nitrogen fertilizer (0, 40 and 80 Kg from urea) and phosphorous fertilizer (0, 30 and 60 Kg from super phosphat treepal) on yield and essetial oil production of Matricaria recutita L. an experiment has been conducted on the basis of randomized complete block design in three replications at 2007. The results showed that there is significant difference in number and dry weight of flowers between nitrogen fertilizer treatments at the level of 1%. Treatment of 40 kg nitrogen by producing 742.2 flower and 20.63 gr dry weight had the highest yield. Control samples produced 507.06 number of flowers and 10.06 gr dry weight, which is at itś lowest amount. Among phosphorous fertilizers, there is significant difference and the highest yield refers to 60 kg phosphate in hectare. It produced 816.26 number of flowers and 30.17 gr dry weight. Thus, the best recommended treatment is 2nd level of nitrogen fertilizer and 3rd level of phosphate fertilizer, with 40 kg nitrogen and 60 kg phosphate in every hectare. There was no significant difference in chamazolene percentage in all treatments.

Various studies indicated that the phytoestrogenic components exist in the Matricaria recutita L. Phytoestrogens act as a weak agonist and/or antagonist of estrogen receptors. On the other hand, it has been showed that the sex hormones affect dependency of narcotic drugs. In the present study the effect of aqueous and hydroalcholic extract of Matricaria recutita on morphine withdrawal signs in presence and/or absence of estrogen receptor antagonist were investigated. Male adult wistar rats weighing 240±30 gram classified in groups of seven were used. Morphine and naloxone were applied for dependence and withdrawal syndrome induction, respectively. Rearing, jumping and grooming were evaluated. Tamoxifen (0.5 mg/kg) as an estrogen antagonist was applied. High performance liquid chromatography (HPLC) was used for comparison between phytoestrogenic components of both extracts. Results showed that: 1) Hydroalcoholic extract of Matricaria recutita decreased rearing and grooming significantly but aqueous extract attenuated only rearing, therefore hydroalcoholic extract of MR had more sedative effect than the aqueous extract. 2) Tamoxifen prevented the MR induced rearing decline, but increased grooming sign in presence of both extract. 3) Tamoxifen increased jumping and grooming behaviors but decreased rearing sign. 4) HPLC showed the presence of apigenine and chrysin (phytoestrogenic components) in aqueous and hydroalcoholic extract of MR but the extraction amount of them was more in hydroalcoholic than the aqueous extract. It seems the phytoestrogenic components of both MR extracts induce sedative effect on some of morphine withdrawal behaviors and probably by interaction with some neurochemical systems of dependence phenomena in central nervous system.

Field experiment was carried out at the Ferdowsi University Research Field, Mashhad, Iran during 2007-2008, to determine the effect of different drying temperatures, microwave powers and natural method (shaded and sunny area) in Chamomile (Matricaria recutita L., Asteraceae) essential oil content, chamazolene content, drying time and drying rate. The experimental design was completely randomized block design having three temperatures: 50, 60 and 70 °C, six microwave powers: 100, 180, 300, 450, 600 and 900w and drying in shaded and sunny area, replicated thrice. The drying process was continued until the mass of the sample reduced to a moisture content of about 0.10 on a dry basis or 10% on a wet basis. The results indicate that different treatments of drying had a significant effect on the drying time and rate and essential oil and chamazolene content. The maximum essential oil content obtained at drying by the lowest temperatures and drying in shaded area. Whereas, higher drying temperatures of oven and microwave powers and drying in sunny area decreased the essential oil content. Maximum chamazolene content obtained at microwave drying (except 100w power) and natural method. Minimum chamazolene content was obtained at drying by oven.

There are limited information about phytoestrogenic components on physiological phenomena and their interactions with endogenous estrogens. The aim of this investigation to examined the phytoestrogenic effect of Matricaria recutita L. (MR) and it is relationship with endogenous estrogens on locomotor activity with administration of estrogenic receptors antagonist (tamoxifen) on adult female mice. 49 NMRI adult female mice weighted 32±3 grams in 7 groups (each group was 7 mice) receiving: 1) saline, 2) MR (50 mg/kg), 3) tamoxifen (0.1, 0.5, 0.75 mg/kg, in 3 separate groups), 4) saline + MR, 5) tamoxifen (0.5 mg/kg) +MR were used. Motor activity monitor was used for locomotor activity evaluation. Four locomotors parameters such as fast and slow activity and fast and slow rearing were measured. The results showed that: MR (50 mg/kg) increase significantly the fast activity and slow rearing in female mice and partially the other locomotor parameters. Tamoxifen (0.5 mg/kg) decreased fast and slow activity in female mice and other doses had no effect. Most of locomotor parameters decrease significantly in presence of MR and tamoxifen (0.5 mg/kg). It seems MR affects locomotor activity parameters through the estrogenic receptors, and the presence of this receptors and endogenous estrogens are essential for action of its phytoestrogenic components.
