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.

“…The use of plant extracts and essential oils as an alternative treatment has also been discussed as a promising practice in controlling diseases. As the work of Cakir et al (2005), who reported the fungicidal effect of the essential oil from Hypericum linarioides Bosse in six species of the genus Fusarium, among them, F. oxysporum. Bajpai et al (2007) found the antifungal effect of the essential oil from Metasequoia glyptostroboides Miki ex Hu, at 1000 μL -1 showing inhibition on mycelial growth of Fusarium oxysporum at 63%.…”

The current research aimed to study the efficacy of plant extracts and essential oils from Rosmarinus officinalis, Thymus vulgaris, Cinnamomum zeylanicum and Syzigium aromaticum on mycelial growth and conidial germination of Fusarium oxysporum f. sp. cubense in vitro, as well as evaluation in vivo. Essential oils and extracts were applied in the culture medium (PDA) at melting point to estimate the direct effect on mycelial growth. Also, the estimation of volatile substances against mycelial growth was done. The obtained results indicated that plant extracts and essential oils of Cinnamomum zeylanicum and Syzigium aromaticum were effective at 500 ppm with direct effect against mycelial growth. The volatile plant extracts had no effect on mycelial growth, however, the volatile essential oils of Cinnamomum zeylanicum and Syzigium aromaticum showed good effects in controlling the disease in both 1000 and 2000 ppm. Meanwhile, extracts and essential oils of Cinnamomum zeylanicum and Syzigium aromaticum showed efficacy on the conidial germination. In vivo, both essential oils and extracts from Cinnamomum zeylanicum and Syzigium aromaticum, in addition to fungicide (Trifloxystrobin + Tebuconazole) which was effective in avoiding the spread of disease.

“…The antiinflammatory effect of α-humulene was also investigated (Fernandes et al, 2007). With relevance to other sesquiterpene compounds of garden thyme essential oil -δ-cadinene, spathulenol, γ-muurolene -individual activity has not been investigated yet, however, several literature data are available referring to essential oils, rich in these sesquiterpenes, showing antifungal (Cakir et al, 2005), insecticidal (García et al, 2007) and anti-inflammatory effects (Tung et al, 2008).…”

Effects of different factors influencing the essential oil properties of Thymus vulgaris L.

Thymus vulgaris L. is a well-know medicinal and aromatic plant native to the Mediterranean region. The essential oil is considered as the main active constituent, being responsible for its typical odour and taste as well as for several therapeutic effects. Our aim was to demonstrate the most important factors influencing the quality and quantity parameters of thyme oil by summarizing the available literature data and our own scientific results. Genetic background, climatic and growing conditions, techniques of primary processing, storage conditions as well as different extraction methods have proven effects on the essential oil properties and, as a consequence, on its biological activity, either.
