Context: A number Hypericum species are well known for their therapeutic efficacy and use in traditional medicine. The various species of Hypericum have been traditionally used for the treatment of wounds, eczema, burns, trauma, rheumatism, neuralgia, gastroenteritis, ulcers, hysteria, bedwetting and depression. Objective: This study evaluated the in vitro antioxidant, antibacterial and phytochemical properties of essential oils of Hypericum helianthemoides (Spach) Boiss., Hypericum perforatum L. and Hypericum scabrum L. (Hypericaceae) collected from alpine region of Southwest Iran. Materials and methods: The essential oils obtained from dried flowering aerial parts of three Hypericum species were analyzed by gas chromatography and gas chromatography/mass spectrometry to determine chemical compositions. The antibacterial activity of essential oils within concentration ranges from 16 to 500 mg/mL was individually evaluated against Bacillus cereus, Listeria monocytogenes, Proteus vulgaris and Salmonella typhimurium. The 1,1-diphenyl-2-picrilhydrazyl (DPPH) radical scavenging activity of essential oils was determined using DPPH assay. Results: Essential oil yield of H. helianthemoides, H. scabrum and H. perforatum were 0.12, 0.20 and 0.21 mL/100 g dried material, respectively. The major constituents of the essential oils were a-pinene (12.52-49.96%), b-pinene (6.34-9.70%), (E)-b-ocimene (4.44-12.54%), b-caryophyllene (1.19-5.67%), and germacrene-D (2.34-6.92%). The essential oils of three Hypericum species indicated moderate-to-good inhibitory activities against four bacteria, especially against L. monocytogenes. Discussion and conclusion: The essential oils of the three studied Hypericum species sourced in alpine region of West Iran were rich in monoterpene and sesquiterpenes hydrocarbons. Among the three tested species, the essential oil of H. scabrum showed the highest antibacterial and antioxidant activities.

“…However, morphological and physiological characteristics are also affected by altitude [29] and seasonal variation [30]. The depth of soils in Chelgerd region increased with increasing altitude and the content of many of components of essential oil was increased [9,13,27,[31][32][33].…”

This study investigated the quantitative and qualitative effects of climate and soil properties on essential oil content and composition of Cirsium arvense L. (Asteraceae), which is an important medicinal plant. Root, stem, and leaf tissues were collected from plants found in four regions (Shahrekord, Farsan, Chelgerd and Ardal) of the Chaharmahal and Bakhtiari Province, Iran. GC/MS analysis revealed that the main constituents of essential oils from the various populations were nonadecane, β-citronellol, camphor, heneicosane and phytol. The highest levels of nonadecane (40.1-42%) and camphor (18.1-18.4%) were obtained from roots collected from the Chelgerd region, the most levels of β-citronellol (24.9-25.01%) were obtained from leaves from the Chelgerd region, and the most levels of heneicosane (14.4-15.6%) and phytol (11.8-12.58%) were obtained from stems from the Shahrekord region. The most amount of essential oil (0.34-0.33%) was obtained from roots growing in clay soil in the Chelgerd region. Both climate and soil properties had significant effects on the essential oil of C. arvense. The highestt essential oil contents were obtained from plants growing in clay soil, which seemed to have a greater capacity to hold water and nutrients, both of which promote plant growth and essential oil production.

“…According Teixeira et al, (2013) the extracts and essential oil of O. vulgare have significant potential to be used as an alternative to synthetic chemicals in the food industry where the oxidation and microbial contamination are problems. The authors have investigated the antibacterial activity of extracts and essential oil of oregano to various pathogenic bacteria causing food spoilage.…”
