    Eryngium caucasicum Trautv. (Apiaceae) is a perennial herbaceous plant with about one meter height, an endemic species that has been distributed in the northern parts of Iran. The plant leaves are normally used in medicine and food industries in Iran.The plant has several medicinal properties including enforcing generative power, diuretic, lenitive and appetizer. In this research differents parts of plants (flower, leaves, stem and roots) from two locations littoral and unlittoral early reproductive phase are collected. The essential oils obtained by three methods of distillation (water distillation, steam distillation and hydro-steam distillation), the composition of essential oils was analyzed by gas chromatography (GC) and gas chromatography, coupled to mass spectrometry (GC-MS). Essential oils content in flower of plants from littoral and unlittoral locations in hydrodistallation method with mean of 0.32% and 0.38% and water and steam distillation with 0.176% and 0.21% in hydro-steam distillation  with 0.06% and 0.09%, respectively. Essential oils content in fresh leaf  also were with hydrod-istallation method with mean of 0.13% and 0.19% and steam distillation with 0.1% and 0.14%, hydro-steam distillation 0.1% and 0.16%, respectively. Essential oils content in dry leaf of plants with hydro-distallation method with mean of 0.17% and 0.32% and steam distillation 0.053% and 0.087%, in hydro-steam distillation with mean of 0.1% and 0.16%, respectively. Main components in flower were allo-aromadendrene (48.7 up to 71.6%), trans-calamenene (11 up to 18.2%), and dehydro abietal (1.2 up to 10.9%), respectively. Main components on fresh and dry leaf from littoral location were allo-aromadendrene (1.5 up to 30.6%), dihydro tagetone (2.9 up to 19.8%), (E,E)-farnesol (0.5 up to 28.3%), respectively. Main components on fresh and dry leaf from unlittoral location were allo-aromadenderene (13 up to 33.2%), dihydro tagetone (1.8 up to 17.9%), α-calacorene (7.7 up to 23.1%), (E,E)-farnesol (12.1 up to 17.5%), respectively. Main components on stem from both location were dihydro tagetone (1.6 up to 9.4%), allo-aromadendrene (36.0 up to 67.4%), trans-calamenene (8.3 up to 16.2%), dehydro abietal (6.3 up to 19.5%), respectively. Main components on root from both location were n-octadecanol (43.5 up to 91%), dihydro tagetone (1 up to 4.9%), γ- cadinene (0.5 up to 1.4%), respectively

    The genus Boswellia is one of the 17 genera belonging to Burseraceae family. In this study resin of Boswellia carteri birdwoodcollected or purchased from Tehram herbal Market as a food and non-food for chemical analysis. The essential oils of the resins of Boswellia carteri birdwoodobtained by different methods of distillation (water distillation, steam distillation and hydro-steam distillation), the composition of essential oils was analyzed by gas chromatography (GC) and gas chromatography, coupled to mass spectrometry (GC-MS). The major components of the different methods of distillation oils of Boswellia carteri birdwood as a non-food by hydro-steam distillation were dihydro citronellol acetate (48%), 2-phenyl ethyl anthranilate (11.5%), α-santonine (7.7%), and with water distillation were dihydro citronellol acetate (48.2%), borneol (8.6%), methyl decanoate (7.9%), and with steam distillation were dihydro citronellol acetate (60.6%), borneol (9.7%), (Z)-β-ocimene (5.3%), respectively. Also the major components of Boswellia carteri birdwood as a food by hydro-steam distillation were dihydro citronellol acetate (55.6%), α-santonine (9%), 2-phenyl ethyl anthranilate (7.3%), and with water distillation were dihydro citronellol acetate (63.7%), borneol (9.1%), 2-phenyl ethyl anthranilate (3%), and with steam distillation were dihydro citronellol acetate (55.9%), (E)-phytol acetate (7.5%), borneol (7.3%), were the predominant major compounds respectively

    Lavandula angustifolia Mill. syn. Lavandula officinalis Chaix was commonly known as lavender is a species of the genus Lavandula from Lamiaceae family is among the top 10 pharmaceutical plant. Lavender species are grown worldwide primarily for their essential oils, which are used in the food processing, aromatherapy products, cosmetics and perfumes. The purpose of this study was to investigate the essential oils composition of lavender (Lavandula officinalis L.) cultivated in 3 provinces, Esfehan, Tehran, and Alburzprovincein Iran. This research examines it has been done on effects of different methods of distillation and habitat conditions on quantity and quality of oil of Lavandula officinalis flowering top plants cultivated in three regions were collected and after drying at room temperature in shadow. Esstential oils were extracted with three methods of distillation (water, steam and water and steam). Thirty compounds were identified in the essential oils, respectively. Components of essential oils from the Lavandula officinalis L. were determined using gas chromatography (GC) and Gas Chromatography- Mass Spectrometry (GC-MS). The important components in the Kashan area from Isfahan provincewere1,3,8-p- menthatriene (37.7 upto 39.8%), γ- terpinene (17.1 upto 19%), Linalyl formate (13.1 upto 15.08%), oil yield were 8.54 upto 10.03%, respectively. The important components in the Alburzprovince were ,3,8-p-menthatriene (31.7 upto 34.2%), γ- terpinene (24.2 upto 26.4%), Linalyl formate (11.8 upto 14%), oil yield were 5.5 upto 6.12%,  respectively. The important components in the Tehran province were 1,3,8-p- menthatriene (32.5 upto 34.1%), γ- terpinene (25 upto 29.8%), Linalyl formate (7.8 upto 9%), oil yield were 10.26 upto 12.13%, espectively

    A sensitive method based on the preconcentration of uranium on modified filter paper (thin film) has been developed to determinate this element in water and soil samples by wavelength dispersive X-ray fluorescence. Uranium (VI) extraction from nitric acid medium by trioctyl phosphine (TOPO) from 100 mL of sample was carried out. The effects of nitric acid concentration, TOPO concentration and sample breakthrough on uranium extraction were investigated in this study. The proposed method provided good linearity from 7 to 1000 µg and the limit of detection (LOD), based on a signal-to noise ratio (S/N) of 3, was 2.5 µg

    The heritage ‘NGO’: a case study on the role of grass roots heritage societies in Iran and their perception of cultural heritage

    This paper examines the activities of a group of heritage enthusiasts in Iran. Grass roots heritage activism is a relatively recent phenomenon that appeared in Iran since the late 1990s. They are increasingly operating collectively as cultural or heritage NGOs. They have diverse socio-economic origins and political views. However, as this paper argues, they share a common ground in their activities; one that maintains an ambivalent and critical relationship with the state and official definitions of heritage and identity. Referring to interview and other data collected during fieldwork in Iran, this paper traces and analyses the contours of that common ground and argues that there is a nascent heritage movement in the country. The impact and contribution of these emerging and self-reflective heritage movements to Iranian identity, which is reflected in their embracing of diversity and the notion of historical continuity, reveal the dynamism and complexity of the cultural and political landscape of contemporary Iranian society. They also reveal the importance of generating further scholarship in the field of Iranian cultural heritage. In conceptualising the characteristics of a nascent heritage movement in Iran, the paper makes a new contribution to the approach of existing scholarship in the broader field of heritage studies
