“…A low monoterpenes content (1.3 %) characterized the oil. The major constituents were n-undecane (32.2 %), patchoulene (11.8 %) and caryophyllene oxide (9.3 %), which are not significantly represented in the essential oils of other species of the genus Hypericum examined 30 .…”

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.

“…Only a small part of the genus has been studied, and the chemical content of approximately threequarters of Hypericum species has not been surveyed (Karioti and Bilia 2010). However, some authors have found that H. maculatum synthesizes and accumulates hypericin (Bagdonait_ e and Kazlauskas 2006; Mártonfi et al 2006), essential oils and flavonoids (Gudžić et al 2007;Smelcerovic et al 2007) in amounts close to those detected for H. perforatum. Hypericum hirsutum L. (hairy St. John's wort) is another less well-studied species that may synthesize moderate quantities of hypericins and hyperforin (Kusari et al 2009;Smelcerovic et al 2006) as well as appreciable amounts of essential oils ).…”

We investigated the effects of plant growth regulators [6-benzyladenine (BA), kinetin (Kin), 6-c, c-dimethylallylaminopurine (2iP), thidiazuron (TDZ) and a-naphthaleneacetic acid (NAA)], modified Murashige and Skoog (MS) medium containing 10 mM NH 4 ? and 5 mM NO 3 -and supplemented with 2iP, BA, Kin and NAA (MSM medium), and two elicitors [jasmonic acid (JA), and salicylic acid (SA)], on plant growth and accumulation of hypericins (hypericin and pseudohypericin) and hyperforin in shoot cultures of Hypericum hirsutum and H. maculatum. Our data suggested that culture of shoots on MS medium supplemented with BA (0.4 mg l -1 ) or Kin (0.4 mg l -1 ) enhanced production of hypericins in H. maculatum and hyperforin in H. hirsutum. Hypericins and hyperforin concentrations decreased in both species when TDZ (0.4 mg l -1 ) was added to the MS medium. Also, TDZ induced hyperhydric malformations and necrosis of regenerated shoots. Cultivation of H. maculatum on MSM medium resulted in approximately twofold increased production of hypericins compared to controls, and the growth of H. hirsutum shoots on the same medium led to a 6.16-fold increase in hyperforin production. Of the two elicitors, SA was more effective in stimulating the accumulation of hypericins. At 50 lM, SA enhanced the production of hypericin (7.98-fold) and pseudohypericin (13.58-fold) in H. hirsutum, and, at 200 lM, enhanced the production of hypericin (2.2-fold) and pseudohypericin (3.94-fold) in H. maculatum.

Experimental Plant materialThe plant material was collected in Rtanj, Serbia, at the blooming stage (July 2000). A voucher specimen is deposited in Herbarium Moesicum Doljevac (HMD; no. 367). Dried and pulverized aerial parts of the plant (100 g) were hydrodistilled for 2.5 h using a Clevengertype apparatus. 14-16 Identification procedureThe oil analysis was performed using GC and GC/ MS. Constituents of the oil were identified by comparison of their mass spectra to those from the MS library (Wiley 275.l) using a computer search and literature. 17 For the purpose of quantitative analysis the area percentage obtained by FID was used as the basis. The GC analysis of the oils was carried out on a GC HP-5890 II apparatus, equipped with the split-splitless injector, attached to an HP-5 column (25 m × 0.32 mm; 0.52 µm film thickness) and fitted to FID. The carrier gas flow rate (H 2 ) was 1 ml/min, the split ratio 1:30, the injector temperature 250°C and the detector temperature 300°C, while the column temperature was linearly programmed from 40 to 240°C at the rate of 4°C/min. The same analytical conditions were employed for GC/MS analysis, where an HP G 1800C Series II GCD system was used. The transfer line was heated to 260°C. The mass spectra were acquired in EI mode (70 eV), in m/e range 40-400 (column HP-5MS 30 m × 0.25 mm, 0.25 µm film thickness).
