“…This is also important intraspesific means. Comparing the results of two plant material each other and with those reported for the other Hypericum species and their different locality patterns 14,15,18,24 , profound differences not only in the identity of chemical components but also in their percentage were revealed in the composition of the essential oils. Nevertheless, regarding the qualitative pattern of the essential oils of Hypericum species, there are similar results for α-pinene, major/high component reported for Greek and Portuguese specimens of H. perfoliatum 12,[15][16] 23. Thus in general, the first major compound of Hypericum species like as, H. scabrum and H. dogonbadanicum is α-pinene, which is a major and characteristic constituent of many Hypericum species mentioned above and following like; H. perforatum 25 , H. forrestii 26 , H. triquetrifolium 22 , H. hircinum 27 , H. hyssopifolium and H. heterophyllum 28 .…”

“…Concerning the major constituents of the Hypericum essential oil; H. tomentosum, menthone was the important feature of this oils according to the Hosni et al 18 while β-caryophyllene was reported as the characteristic component of Portuguese specimen 24. The geographical distribution and analysis of the essential oils of species from three sections of Hypericum from Portugal were presented as monoterpene hydrocarbons constituted the main fraction in all oils (43-69 %, 53-85 %, 28-45 % and 48-65 % for H. perfoliatum, H. humifusum, H. linarifolium and H. pulchrum) respectively. Sesquiterpene hydrocarbons (2-13 %, 6-18 %, 21-27 % and 16-18 %, respectively) and a third fraction of non-terpenic compounds (20-29 %, 3-16 %, 2-14 % and 5-11 %, respectively) from the four species attained relatively high amounts in all oils 24 .…”

Although different compositions of essential oils of Hypericum perforatum 14 and H. perfoliatum [15][16][17][18] have been previously reported, studies have also been reported on the essential oil constitution of other species from this genus (e.g. H. foliosum, H. maculatum, H. coris and H. triquetrifolium) [19][20][21][22] and no previous study was found on the essential oil composition of H. pseudolaeve and H. thymbrifolium.…”

In this study, essential oil composition of two Hypericum L. (Hypericum pseudolaeve Robson and H. thymbrifolium Boiss. & Noë ) species grown in Turkey were determined by using GC and GC-MS system. The essential oils obtained by hydrodistillation from the aerial parts of plants. Forty-five compounds were identified in the essential oils of H. pseudolaeve; transcaryophyllene (23.92 %), δ-limonene (11.19 %), α-cadinol (10.67 %), caryophyllene oxide (7.96 %), α-pinene (5.76 %), spathulenol (5.21 %) and β-selinene (3.02 %). Fifty-four components were identified in H. thymbrifolium oil, α-pinene (51.31 %), undecane (4.94 %), germacrene D (4.70 %), β-pinene (3.68 %), β-myrcene (3.30 %), spathuleneol (2.92 %) and naphthalane (1.88 %) were determined as the main constituents. Monoterpenes were shown to be the main group of the H. thymbrifolium, while the H. pseudolaeve were more rich in sesquiterpenes. The results have supplied contributions on the usability of oils as renewable resources and chemotaxonomy of plants.

“…Chemicals were identified by using the NIST mass spectral program version 2.0 d and the NIST/EPA/NIH mass spectral library (NIST05) when Reverse Matches and Matches were >950 and >900‰, respectively. For each sesquiterpene, the Kovats Retention Index (RI) was compared with the RI calculated from synthetic chemicals when commercially available [RI=1358, 1391, 1442, 1477 for α-cubebene (Bedoukian Research Inc., Danbury CT, USA), α-copaene (Fluka Analytical, Stenheim, Germany), β-caryophyllene (Sigma Chemical Co., St. Louis, MO, USA), and α-humulene (Sigma), respectively] or with previously published data [δ-elemene (Singh et al, 2007), β-elemene (Hosni et al, 2008;Karlsson et al, 2009), alloaromadendrene (Tokushima et al, 2010), cadinene (Singh et al, 2007;Ibrahim et al, 2010), and calamenene (Ibrahim et al, 2010)]. …”

Attraction of the Redbay Ambrosia Beetle, Xyleborus glabratus, to Avocado, Lychee, and Essential Oil Lures

The redbay ambrosia beetle, Xyleborus glabratus Eichhoff, is an exotic wood-boring insect that vectors the mycopathogen responsible for laurel wilt, a lethal vascular disease of trees in the Lauraceae. High mortality has occurred in native Persea species in the southeastern U.S., and the vector-pathogen complex poses an imminent threat to the production of commercial avocado, P. americana, in south Florida. There is a critical need for effective attractants to detect, monitor, and control this invasive pest. This study combined field tests and laboratory bioassays to evaluate the response of female X. glabratus to host-based volatiles from wood of avocado (cultivars of West Indian, Guatemalan, and Mexican races); from wood of lychee (Litchi chinensis, a presumed non-host that is high in the sesquiterpene α-copaene, a putative attractant); and to commercial lures containing manuka and phoebe oils, two reported attractive baits. Volatile collections and GC-MS analyses were performed to quantify the sesquiterpene content of test substrates. In the field, traps baited with lychee wood captured more beetles than those with wood from avocado cultivars; traps baited with phoebe oil lures captured more beetles than those with manuka oil lures (the current monitoring tool). In field and laboratory tests, X. glabratus did not show a preference among avocado races in either attraction or host acceptance (initiation of boring). In choice tests, lychee was more attractive than avocado initially, but a higher percentage of beetles bored into avocado, suggesting that lychee emits more powerful olfactory/visual cues, but that avocado contains more of the secondary cues necessary for host recognition. Emissions of α-copaene, β-caryophyllene, and α-humulene were correlated with field captures, and lychee wood may be a source of additional semiochemicals for X. glabratus.

“…The obtained distillate was extracted twice with n-pentane and dried over anhydrous sodium sulphate (Na 2 SO 4 ). Choice of the solvent was based on its ability to extract the major constituents of the essence without loss of the high volatile components [8,9]. The n-pentane extract of aromatic water was then concentrated, at 35…”

The volatile oils of R. canina flowers were isolated by hydrodistillation (HD) and traditional dry distillation (DD) and analyzed by HRGC-FID and GC-MS. Compared to HD, DD at 50• C leads to the isolation of high quality oil which contains the highest content of oxygenated compounds (83%). The main components are the 2-phenethyl alcohol and eugenol. The percentage of the 2-phenethyl alcohol, a highly desirable component in rose oil, was significantly higher (58.4%) in DD extract when compared to that of HD one (13.6%). As temperature increased (100• C) during DD, the oil quality decreased. The most significant changes were observed in 2-phenethyl alcohol percentage (4.5%). Moreover, an increase of alkanes/alkenes and the production of furan derivatives were observed. So, DD at moderate temperature (50 • C) seemed more suitable to improve the volatile oil quality and hence, to make more value of R. canina.
