Hypericum genus is one of the most important medicinal plants in Iran. Currently in Iran, there are 17 herbaceous, perennial and shrub species of Hypericum of which three species are endemic to Iran. This research was aimed to investigate Hypericine content in nine species of Hypericum. For Hypericine content 1 gram of plant was extracted in two steps, chloroform extraction then methanol extraction using a Soxhlet device. Hypericin content was measured by HPLC, using the following condition, mobile phase: (methanol 68%, ethyl acetate 20% and sodium hydrosulphate (0.1 M) 12%) and stationary phase C18, and UV detector: set on 590 nm. Generally, no hypericin was detected in different organs of H. androsaemum L. Hypericine content detected in flowers, leaves and stems were: H. apricum Kar. & Kir. (in flowers 0.061% and leaves 0.005%), H.armenum Jaub. & Spach (flower 0.003%), H.asperulum Jaub. & Spach (in flower 0.025%, leaves 0.004% and stems 0.003%), in H.hirsutum L. (flower 0.007%), in H.linarioides Boss. (flower 0.007%), in H.tetrapterum Fries (flowers 0.008%, leaves 0.014%, and stem 0.001%), and H.vermiculare Boiss. & Hausskn. (flowers 0.005%), in H.perforatum L. (flowers 0.124%, leaf 0.028% , stem 0.003).

The genus Bunium comprised of 14 species in Iran, two of them (B. wolfi and B. lurestanicum) are endemic. Among these species, only B. persicum is famous and used in medicinal and nutrition industries. In this research, two other species of Bunium named as B. cylindricum (Boiss.& Hohen.) Drude and B. rectangulum Boiss.& Hausskn., were studied. At first, different parts of these plants were collected from their habitats. Different parts were separated and then dried. The dried plant materials were subjected to hydro-distillation for obtaining the essential oils. The oils were analyzed by GC and GC/MS. Seventeen components were characterized in the oil of aerial parts of B. cylindricum at flowering stage. Germacrene D (31.2%), dill apiol (26.9%), E- caryophyllene (11.6%) and germacrene B (7.1%) were the main constituents. 20 compounds were identified in the seed oil of B. cylindricum with dill apiol (25.8%), E- caryophyllene (15.4%), globulol (12.2%), spathulenol (7.2%) and germacrene D (6.6%) as main components. 11 compounds were identified in the seed oil of B. rectangulum with dill apiol (63.3%), Germacrene D (22.4%) and E-caryophyllene (5.1%) as main components. 21 components were characterized in the flower oil of B. rectangulum. Germacrene D (36.7%), Dill apiol (11.1%), bicyclogermacrene (16.5%) and E-caryophyllene (15.9%) were the main constituents. The results showed that the essential oils of both species contained mainly sesquiterpens, but the percentages of these compounds were different.

In order to study the effects of irrigation and dry farming condition on growth indices of yarrow (Achillea millefolium L.) an experiment was carried out in Alborz Research Center during 2005-2006. In the first year after planting, the plants viability investigated in dry farming condition and growth physiological indices were determined. In the second year, the treatments were irrigated based on total accumulated evaporation from class A pan namely at the rate of 30 mm (mild stress), 60 mm (medium stress), 90 mm (severe stress), full irrigation (no stress) and no irrigation (control). For each treatment, the soil moisture content was measured by weighting method (daily) before and after applying irrigation treatments. The amount of water requires for each treatment was measured by water meter.In the second year, the growth physiological indices were also determined. The results showed that, at the first year, dry matter cumulated to 2250 GDD then reduced during growth. In second year, the plants with no irrigation were died. In other treatments, by increasing soil moisture from severe to medium, the dry mater cumulative and Leaf area index increased. In all of the stress treatments, decreasing in plant growth was observed in 3000 GDD. The results showed that, mild water stress had highest performance than other treatments.

Agrimonia eupatoria L. is a perennial plant that has been distributed in Iran. Its effective components are used to cure some diseases such as hepatitis, control bleeding sedative, and balance especially in women menstrual. The purpose of this investigation was finding the best time and the normal distances in cultivation on seed yield. Three stand density as 30, 40, 50cm (4, 6.2 and 9.2 per m-2) and four planting dates were based on factorial design with three replications, in research institute of forest and rangelands. Results showed 4/m-2 had significant differences on seed yield.
