Hypericum Perforatum L

Abstract Aerial parts of Hypericum perforatum L. (Hypericaceae) were collected from five wild populations in Kosovo, with aim to investigate the chemical composition and natural variation of essential oils between wild populations. This species could be considered of economic potential as it is widespread in Kosovo, on the other hand H. perforatum is one of the best-known medicinal herbs used in Kosovo folk medicine. Essential oils were obtained by steam distillation and analysed by GC-FID and GC-MS. Sixty-seven components were identified. The yields of essential oils differed depending on the population and ranged from 0.04 to 0.26% based on dry weight. The aerial parts of H. perforatum were characterized by the following main constituents: 2-methyl-octane (1.1-15.5%), α-pinene (3.7-36.5%), β-caryophyllene (1.2-12.4%), caryophyllene oxide (3.3-17.7%) and n-tetradecanol (3.6- 10.4%). Hierarchical cluster analysis revealed that the concentration of components depends on the origin of the plant populations, thus α-pinene and 2-methyl-octane were present in the highest concentration in population originating from Gjakove, Prizren and Ferizaj, whereas in the populations originating from Peje and Prishtine the most abundant constituents were caryophyllene oxide, β-caryophyllene and n-tetradecanol. Further investigation is needed to establish the natural variability and chemopolymorphism of this species in the territory of Kosovo, which should be supported by molecular level analyses.

The chemical composition of essential oils obtained by hydrodistillation method from two plants of the genus Scutellaria, grown in Uzbekistan and used in folk medicine were comparatively investigated by GC/MS and FID. Overall individually thirty three constituents were identified in both of aerial parts of S. adenostegia and S. comosa essential oils, representing 94.4 and 97.0% of the total, respectively. The main components were determined as acetophenone (24.2%), eugenol (12.3%), caryophyllene oxide (8.9%), and β-caryophyllene (7.0%) in the oil of S. adenostegia. β-Caryophyllene (12.5%), phytol (11.4%), linalool (11.1%), acetophenone (10.4%), caryophyllene oxide (6.6%),1-hexanol (5.3%), and (E)-2-hexenal (5.1%) were found as major components in the S. comosa oil. The composition of the oils of S. adenostegia and S. comosa was being reported for the first time. The essential oils of S. adenostegia and S. comosa showed significant antimicrobial properties against Bacillus subtilis, moderate effect against Salmonella enterica and Escherichia coli.

The genus Lavandula includes about thirty species plus a number of intraspecific taxa and hybrids, which are distributed in the Mediterranean area. The traditional use of lavender both as perfume or medicinal plant is known since antiquity. Nowadays several species are extensively cultivated for the extraction of their essential oils (EOs) which are used in manufactured products like cosmetics and perfumes or in phytotherapy. Lavandula pinnata L. f. (syn L. pinnata Lundmark) is a rare species native to the Canary Islands used in folk medicine as relaxant and also a valuable remedy against bites. To the best of our knowledge, EOs from L. pinnata have been very little studied. The present paper reports on the quali- and quantitative compositional profile of the EOs distilled (by a Spring type apparatus) from the aerial parts (flowers and leaves) of this species cultivated in soilless conditions. Chemical analyses by means of GC and GC-MS techniques have indicated that oxygenated monoterpenes are the main constituents of both the flowers (68.30%) and the leaves (83.65%). Carvacrol is the main compound which characterizes the EOs of this species. In addition, discrete amounts of spathulenol (12.22%) and caryophyllene oxide (14.62%) have been detected in flowers EOs, while leaves EOs contained small amounts of carvacrol methyl ether (2.52%).

The chemical composition of the essential oils of aerial parts of Artemisia campestris ssp. campestris, collected from ten different locations in Lithuania is detailed in this paper. The major component in all the oils was caryophyllene oxide (8.5-38.8%), whereas compounds with the caryophyllane skeleton ranged from 10.2 to 44.5%. Other representative constituents were germacrene D (≤15.0%), humulene epoxide II (≤8.1%), β-ylangene (≤7.7%), spathulenol (≤6.8%), β-elemene (≤6.8%), β-caryophyllene (≤6.2%), junenol (≤6.1%) and α- or β-pinene (≤5.5%). Eighty-seven compounds were identified, comprising 73.6-92.3% of the oils. The chemical composition was highly variable depending on the sample location. Toxicity of A. campestris oils was determined using the brine shrimp (Artemia sp.) assay. LC50 values ranging to 20 μg/mL were obtained for three of the oils after 24 hours of exposure. Data of this test revealed that A. campestris ssp. campestris essential oils with dominant caryophyllene oxide are notably toxic.

Essential oils of Piper subtomentosum (leaves and inflorescences) and Piper septuplinervium (aerial parts) were analyzed by GC-MS; sixty-three compounds were determined, representing 92.0%, 86.9 %, and 91.8 % of the total relative oil composition of the leaves, inflorescences, and aerial parts, respectively. The most abundant component in the aerial parts and inflorescence oils was α-pinene (27.3%, 21.0%, respectively), and δ-cadinene was the main component of the leaf oil. Insecticidal activity of the essential oils were determined on the Spodoptera frugiperda second instar larvae; the essential oil from the aerial parts of P. septuplinervium was the most active against insect pests (LC50= 9.4 μL/L of air). Statistical analysis by direct Pearson correlation showed that the insecticidal activity of the essential oils was primarily due to camphene and α- and β-pinene. The effect of the oils on the insect life cycle was also evaluated, and in some cases, a delay in growth and inhibition of the oviposition in the females were observed.

The chemical composition of the essential oils obtained from the aerial parts of Helichrysum cymosum and H. fulgidum, from Tanzania, were analyzed by GC and GC/MS. A total of sixty-five compounds, representing 92.4% and 88.2% of the two oils, respectively, were identified. trans-Caryophyllene, caryophyllene oxide, β-pinene, p-cymene, spathulenol and β- bourbonene were found to be the main components. Furthermore, the oils were tested against six gram (±) bacteria and three pathogenic fungi. It was found that the oil of H. fulgidum exhibited significant antimicrobial activity, while the oil of H. cymosum was not active at all.

AbstractDifferences in essential oil composition of wild Achillea millefolium L., collected at five habitats in Lithuania, where plants with pink (f. rosea) and white (f. millefolium) flowers grow together, were reported. For the first time, oils of different plant organs (inflorescences and leaves) of both forms from every population were analysed in detail. Chemical analysis was performed by GC and GC-MS. The most predominant constituents of the oils were nerolidol (9.4–31.9%, in 11 out of 20 samples), caryophyllene oxide (8.4–23.0%, 4 leaf oils), ß-pinene (8.0–15.2%, 2 samples), eudesmol (11.8–15.8%, 2 leaf oils) and 1,8-cineole (11.9%, one inflorescence oil). Domination of nerolidol was mostly characteristic of A. millefolium f. rosea essential oils (in 8 out of 10 oils). The inflorescences biosynthesised markedly larger amounts of nerolidol and ß-pinene than those of the leaves. An opposite correlation was observed for caryophyllene oxide and eudesmol. Chamazulene (≤2.7%) was determined only in six oils. The 65 identified constituents made up 75.4–96.5% of the oils.
