Horehound herb (<em>Marrubium vulgare</em> L.) is harvested from plantations in Poland. In our country, there are also favorable conditions for <em>M. incanum</em> Desr. growing. The aim of the study was to compare the chemical composition of essential oils from <em>M. vulgare</em> L. and <em>M. incanum</em> Desr. in the second year of cultivation. The study revealed the presence of 31 compounds in the essential oil from <em>M. vulgare</em> L. and 24 compounds in the essential oil from <em>M. incanum</em> Desr. Chromatographic analysis revealed that the main compounds in the essential oil of <em>M. vulgare</em> L. from a two-year plantation were as follows: E-caryophyllene (34.51–36.78%), germacrene D (22.45–27.18%), bicyclogermacrene (9.54–11.12%), δ-amorphene (6.15–8.18%), and carvacrol (4.71–6.64%), whereas the following compounds prevailed in the oil from <em>M. incanum</em> Desr.: germacrene D (28.75–32.14%), E-caryophyllene (23.18–29.57%), α-cadinol (13.59–20.84%), and carvacrol (2.08–7.47%).

AbstractPolyalthia is one of the largest genera in the Annonaceae family, and has been widely used in folk medicine for the treatment of rheumatic fever, gastrointestinal ulcer, and generalized body pain. The present investigation reports on the extraction by hydrodistillation and the composition of the essential oils of four Polyalthia species (P. sumatrana, P. stenopetalla, P. cauliflora, and P. rumphii) growing in Malaysia. The chemical composition of these essential oils was determined by gas chromatography (GC-FID) and gas chromatography-mass spectrometry (GC-MS). The multivariate analysis was determined using principal component analysis (PCA) and hierarchical clustering analysis (HCA) methods. The results revealed that the studied essential oils are made up principally of bicyclogermacrene (18.8%), cis-calamenene (14.6%) and β-elemene (11.9%) for P. sumatrana; α-cadinol (13.0%) and δ-cadinene (10.2%) for P. stenopetalla; δ-elemene (38.1%) and β-cubebene (33.1%) for P. cauliflora; and finally germacrene D (33.3%) and bicyclogermacrene for P. rumphii. PCA score and HCA plots revealed that the essential oils were classified into three separated clusters of P. cauliflora (Cluster I), P. sumatrana (Cluster II), and P. stenopetalla, and P. rumphii (Cluster III) based on their characteristic chemical compositions. Our findings demonstrate that the essential oil could be useful for the characterization, pharmaceutical, and therapeutic applications of Polyalthia essential oil.

In this study, anti-mildew activities of the essential oils of the leaves, wood, twigs, flowers, and their constituents from Michelia compressa var. formosana were evaluated in vitro against 7 mildew fungi. The main compounds responsible for the anti-mildew activities were isolated and identified. The essential oils from the fresh leaves, wood, twigs, and flowers of M. compressa var. formosana were isolated using hydrodistillation in a Clevenger-type apparatus, and characterized by GC-FID and GC-MS. The essential oil yield from the flowers was the highest, and the oils obtained from the 4 parts of the tree were composed mainly of sesquiterpenoids. The leaf oil consisted primarily of α-cadinol (18.9%) and germacrene D (18.5%); the twig oil's main constituent was α-cadinol (19.1%); the wood oil's major components were α-cadinol (25.7%) and β-eudesmol (20.2%); and the flower oil contained α-cadinol (11.4%). Comparing the anti-mildew activities of the oils suggested that wood oil was the most effective. Further fractionation of the wood oil produced α-cadinol, β-eudesmol, τ-cadinol, and elemol. The 4 compounds exhibit very strong anti-mildew activities, and these in descending order are α-cadinol, elemol, β-eudesmol, and τ-cadinol. For the anti-mildew activities of the wood oil, the active source compounds were determined to be α-cadinol, elemol, β-eudesmol, and τ-cadinol.

Essential oils of leaves of the endemic species Piper oradendron Trel. & Standl. (Piperaceae) were obtained from three sites of the Guatemalan Pacific slope. The yields of the essential oils obtained by hydrodistillation varied from the site of collection (0.4-1.4%). The GC/MS analysis showed that sample A (Samayac) had up to 53 peaks that were identified, B (Popoyá) showed 31 peaks and C (Bulbuxyá) showed 22; major constituents were similar in the three samples, including α- and β-pinene (28.3-46.9%), germacrene D (10.7-22.7%), and iso-spathulenol (10.2-22-3%). This is the first report on the chemical composition of the essential oil of samples of P. oradendron from different provenances of Guatemala, suggesting little variability in its main components.

The volatile chemical composition of leaf essential oils of three Annona species (Annona cherimola, Annona muricata and Annona squamosa) from the different regions of Kerala, South Indian was determined using gas chromatography-mass spectrometry analysis. A total of 41 constituents belonging to monoterpenoids, sesquiterpenoids and diterpenoids were identified. Monoterpenes and sesquiterpenoids were the major class of volatile compounds in most of the Annona species examined. The study led to the identification of major compounds as germacrene D (23.5%), bicyclogermacrene (14.6%) and β-caryophyllene (11.7%) in A. cherimola, α-pinene (13.3%), β-caryophyllene (11.2%) and β-pinene (10.1%) in A. muricata, and β-caryophyllene (11.9%) and α-pinene (8.2%) in A. squamosa respectively. The examined essential oils showed that β-caryophyllene is the common constituent identified in all the three species and other constituents are more specific for each species under study. Present investigation reports, a comparison of essential oil compositions of three Annona species from Kerala. Results of this study prove that essential oils examined have considerable dissimilarity in chemical composition with previously reported leaf essential oil compositions from other regions. A chemotaxonomic analysis of these essential oils based on the distribution of compounds has revealed an efficient method to differentiate Annona species unambiguously.

AbstractThe aims of this work are to investigate the chemical composition, the antibacterial activity of the essential oil and the chromosome numbers of two populations of Hertia cheirifolia. The samples were collected in the flowering stage, in eastern Algeria locality. The aerial parts of H. cheirifolia were submitted to a hydro-distillation. GC and GC / MS analysed the chemical compositions of the obtained essential oils. The antibacterial activity of essential oils was evaluated using the disks diffusion method against ten bacterial strains. For karyotypic analysis, the squashing method is used. Fifty-eight compounds representing 98.93% of the total oil were identified in H. cheirifolia. The chemical composition is dominated by the presence of major products, α-pinene (48.49 - 53.85%) and Germacrene-D (2.64 - 12.66%). Two distinct chemical breeds were identified, the α-pinene-spathulenol of Batna population, and the α-pinene-germacrene-D of Setif population. The essential oil of H. cheirifolia has a moderate activity against bacteria tested. In contrast, the strains E. coli ATCC 25922, P. syringae ATCC 53543 and E. fecalis ATCC 49452 are resistant to H. cheirifolia essential oils. The observations of root cells meristematic at metaphase of H. cheirifolia gave a diploid chromosome number 2n = 2x = 20, with a basic chromosome number (x= 10).

Protium ovatum is a Brazilian endemic species widely distributed between the Cerrado and Amazon biomes. Here, we evaluate the chemical composition of the essential oils (EO) of different shoot organs from P. ovatum including stems, petioles, leaves, flowers, ripe and unripe fruits, and investigate their antifungal potential against Sclerotinea sclerotiorum. The EO were obtained by hydrodistillation in a Clevenger-type apparatus and analysed by GC-MS, followed by PCA analysis. The antifungal activity was performed by agar diffusion. Fruits had the highest essential oil contents among the shoot parts. The constituents were found varyingin the different organs: α-Pinene (0.80-18.3%), β-Pinene (0.58-5.17%), Myrcene (0.52-27.3%), Limonene (3.15-59.7%), Caryophyllene E (3.67-16.4%), Germacrene D (6.34-27.4%), and δ-Cadinene (2.29-7.63%). The essential oil from ripe fruit showed the strongest antifungal activity, with the highest Inhibition of Mycelial Growth (IMG) (50.11%) at the lowest concentration assayed (18.75μg.mL-1). This is the first report on the chemical composition of the essential oils from stems, petioles, flowers, and ripe fruits of P. ovatum and their antifungal activity against S. sclerotiorum, making it a potential source of antimicrobial agents

The aerial parts of Hypericum richeri Vill. subsp. grisebachii (Boiss.) Nyman were collected from two different locations in Croatia and subjected to hydrodistillation. GC/FID and GC/MS analysis of the isolated essential oils revealed 64 compounds representing 94.7% and 98.2% of the total oils. Predominant constituents in both samples were: germacrene D (10.9%; 6.0%), bicyclogermacrene (4.7%; 3.5%), α-pinene (6.8%; 6.9%), β-pinene (8.1%; 5.1%), decanoic acid (4.5%; 6.8%), β-caryophyllene (3.3%; 7.5%), δ-cadinene (7.0%; 4.4%), spathulenol (6.0%; 9.5%) and tetracosane (3.1%; 5.8%). Comparison of both samples revealed similarity in the chemical composition with minor fluctuations of constituent percentages. The chemical profile of Croatian oils was in general similar to those reported for other geographic areas regarding major mono- and sesquiterpene constituents. However, spathulenol, 5-cadinene and bicyclogermacrene were more abundant in Croatian oils. The presence of decanoic acid (4.5%; 6.8%) in Croatian oils was the major difference between acids and fatty acids derivatives. Higher abundance of alkanes (particularly tetracosane and docosane) was also noticed.

 The objectives of this work were the study of the volatile chemical composition of essential oils (EO’s) from Swinglea glutinosa, as well as to evaluate their antioxidant, repellent and fumigant properties. The EO was obtained by hydrodistillation from the peel of the fruit, gathered in the city of Cartagena, Bolívar (Colombia). The volatile composition was analyzed by gas chromatography coupled to mass spectrometry (GC-MS). The major compounds found in S. glutinosa were germacrene D (4.8%), limonene (5.2%), a-terpineol (6.5%), b-pinene (8.5%), nerolidyl acetate (9.8%), and trans-nerolidol (34.6%). S. glutinosa showed antioxidant potential (85.8%) (IC50=142.49 µg mL-1). The EO deployed repellent activity against the Tribolium castaneum weevil at a concentration of 15.73 nL cm-1 at 2 hours of exposure (72%), while the result for the commercial repellent was 50% at the same concentration. EO from S. glutinosa displayed the best fumigant activity with LC50 of 153.4 μg mL-1 air. The essential oil from S. glutinosa can be considerated as a natural source of biocides and antioxidants.
