Centaurea zuvandica(Sosn.) Sosn.is a perennial species, distributed in North and North-West of Iran. The shoots of C. zuvandica were collected at flowering stage from Firoozkoh, Ghaemshahr and Chaloos Road, in late June 2011. The plant parts were dried at ambient temperature and milled to small particles. The essential oils of stem as well as leaves and inflorescences were obtained by hydrodistillation and were analyzed by GC and GC/MS. Essential oil yield of different organs varied (w/w dried weight) between 0.02% to 0.07%. The major constituents were: spathulenol (>28.8%), thymol (>21.7%), caryophyllene oxide (>20.9%), linalool (>19.5%), germacrene D (>16.3%) and carvacrol (>6.8%). According to the obtained results, a high variability was found for the major essential oil constituents among three studied localities and even among different organs of a locality. The major constituent in the stem and leaf oils, collected from Chaloos Road and Firoozkoh localities, was thymol (17.8% and 21.7%). Linalool (19.5% and 9.7%) was the major constituent in inflorescence oils, collected from Chaloos Road and Firoozkoh localities. For the samples collected from Ghaemshahr, caryophyllene oxide (20.9%) was identified as the major constituent in stem and leaf oil.

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).

Native and endemic plants are considered as genetic reserves of every habitat and due to favorable morphological traits, resistance to pests and diseases and adaptation to ecological conditions are of utmost importance. The aim of the current research was to identify medicinal plants from Arasbaran flora, Mardanaghomchay watershed and ethnobotanical study related to medicinal plants and its determinant factors. To achieve this goal, after identifying the region's flora and separation of the medicinal plants, data were randomly collected through questionnaires as 180 samples were taken from the population over 20 years old. The results showed that 30% of the region's flora included valuable medicinal plants belonging to 56 genera and 30 families, among them Labiatae, Compositae, Rosacea, Urticaceae, Umbellifereae and Grossulariaceae respectively were more harvested by local people for medicinal purposes. Data analysis of the questionnaires in SPSS software with coefficient correlation of Spearman and Kruskal-Wallis test revealed that among the effective factors on identification of medicinal plants in the region, the relationship between knowledge and harvesting of medicinal plants and access to rural health center for treatment was significant (P= 0.05). It means that access to the physician has been effective on knowledge of the local people with medicinal plants and its relation with access of foresters to surrounding towns for cure is significant while there was no significant relation between the knowledge and rural people age, literacy level and the consumption of synthetic drugs (P= 0.05).

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.

The volatile constituents of Anthemis coelopoda Boiss. were isolated by hydrodistillation and analyzed by GC and GC/MS. In this study samples were collected from Gilan province in Rodbar on late May 2003. According to literature, this species was not the subject of research up to now and therefore its chemical composition is not well known. The major constituents of A. coelopoda Boiss. flower oil were Cis-chrysanthenyl acetate (27.3%), hexyl butanoate (16%), and myrcene (7%), while the leaf oil contained isobornyl formate (30.6%), Trans-ethyl chrysanthemumate (15%) and p-mentha-1,5-diene-8-ol (13.7.4%).
