The volatile components of essential oils of fresh aerial parts from horseweed (Conyza canadensis) collected in October with hydrodistillation and steam distillation, respectively, were analyzed by gas chromatography-mass spectrometry. The results showed that limonene, β-pinene, trans-α-bergamotene, cis-β-ocimene, β-myrcene, germacrene D, 1,3,8-p-menthatriene, caryophyllene, (E)-β-farnesene, (Z)-β-farnesene, α-curcumene, caryophyllene oxide were the common volatile components in the essential oils between hydrodistillation and steam distillation. High limonene content (68.87%) was in the essential oil with hydrodistillation. Limonene or other terpenoids has the potential to develop as the biomimetic synthesis template for environmentally-friendly herbicide.

Abstract Thirty-six compounds were identified from aerial parts of Solidago chilensis cultivated at PAF/FIOCRUZ campus in Rio de Janeiro city (RJ) using solid-phase microextraction (HS-SPME) and gas chromatography-mass spectrometry (GC-MS) analysis. These compounds are mainly non-oxygenated mono and sesquiterpenes. Germacrene D is the major compound of two the essential oil analyzed samples (12 to 23%) and of two of the volatiles samples analyzed by SPME (central stems and dry inflorescences samples). Limonene is the major compound in the fresh inflorescences sample (about 21%). The bornil acetate is present in both volatile fractions (16%) and essential oils (7-8%). All the essential oils samples evaluated shown a great antinociceptive activity, considering the used dose of the samples (1 mg/kg) and the standard substance (50 mg/kg). Solidago chilensis is one of Brazil arnicas and it is a medicinal plant widely used by the brazilian population. Other plants of the genus Solidago are also used in traditional medicine in North America and Europe. This is the first report of SPME analysis from Solidago genus and of the antinociceptive effect from Solidago chilensis essential oil.

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.

The composition of the essential oils of flowering aerial parts of Salvia samuelssonii Rech. fil. (Lamiaceae Section Aethiopis), collected in two different biogeographical regions, has been analyzed. Sample1, collected in a Mediterranean-like region, “As-Subayhi”, contains mainly monoterpenes (54.2%), sesquiterpenes (27.6%) and phenylpropanoids (10.5%), while sample 2, collected in the Irano-Turanian region, “Al-Adasiyyah”, contains mainly phenylpropanoids (30.6%), monoterpenes (24.9%) and sesquiterpenes (21.2%). In Sample1, the most representative constituents were sabinene (21.5%), cis-chrysanthenyl acetate (20.8%), germacrene D (9.3%) and myristicin (5.9%), while in sample 2, myristicin (24.1%), sclareoloxide (6.3%), and germacrene D (5.7%) were main constituents. The rate of oxygenated derivatives in the Irano-Turanian sample was higher than the Mediterranean sample. Myristicin is an unusual constituent of Salvia species.

The leaf volatile components of Mexican Bursera linanoe were identified as ( R)-(–)-linalyl acetate (57.6%; 95.5% ee) and ( S)-(–)-germacrene D (39.3%; 100% ee) by solvent extraction and GC–MS and chiral GC analyses. Linalool was previously reported as the major component from the leaves of B. linanoe. However, we believe that this is a decomposition product of linalyl acetate during steam distillation, a common method for extraction of essential oils. The chemically unique blend in the leaves of B. linanoe may act as a chemical barrier against its potential herbivores, Blepharida beetles that have a tendency for attacking chemically similar plants as hosts.

Volatile components fromExocarpium Citri Grandis(ECG) were, respectively, extracted by three methods, that is, steam distillation (SD), headspace solid-phase microextraction (HS-SPME), and solvent extraction (SE). A total of 81 compounds were identified by gas chromatography-mass spectrometry including 77 (SD), 56 (HS-SPME), and 48 (SE) compounds, respectively. Despite of the extraction method, terpenes (39.98~57.81%) were the main volatile components of ECG, mainly germacrene-D, limonene, 2,6,8,10,14-hexadecapentaene, 2,6,11,15-tetramethyl-, (E,E,E)-, andtrans-caryophyllene. Comparison was made among the three methods in terms of extraction profile and property. SD relatively gave an entire profile of volatile in ECG by long-time extraction; SE enabled the analysis of low volatility and high molecular weight compounds but lost some volatiles components; HS-SPME generated satisfactory extraction efficiency and gave similar results to those of SD at analytical level when consuming less sample amount, shorter extraction time, and simpler procedure. Although SD and SE were treated as traditionally preparative extractive techniques for volatiles in both small batches and large scale, HS-SPME coupled with GC/MS could be useful and appropriative for the rapid extraction and qualitative analysis of volatile components from medicinal plants at analytical level.

Essential oils obtained by hydrodistillation of leaves of two Nigerian species were analyzed for their constituents by gas chromatography (GC) and gas chromatography-mass spectrometry (GC-MS). The leaf oil of Ficus benjamina L. (Moraceae), collected during the day, contained high contents of α-pinene (13.9%), abietadiene (9.7%), cis-α-bisabolene (8.2%) and germacrene-D-4-ol (8.4%), while the night sample was dominated by germacrene-D-4-ol (31.5%), 1,10-di- epi-cubenol (8.8%) and hexahydrofarnesylacetone (8.3%). This could be a possible indication of differences in emissions of volatiles by F. benjamina during the day and night. The main compounds of Irvingia barteri Hook. f. (Irvingiaceae) were β-caryophyllene (17.0%), (E)-α-ionone (10.0%), geranial (7.6%), (E)-β-ionone (6.6%) and β-gurjunene (5.1%).

The essential oils from aerial parts and fruits of Anisosciadium orientale DC. growing wild in Iran were obtained by hydrodistillation and analyzed by GC and GC/MS. Seventy-one compounds were identified in the fruit oil and fifteen in the oil from the aerial parts. The main oil components of the fruits and aerial parts were myristicin (33.5%-33.7%), α-terpinolene (22%-25.8%) and limonene (19.5%-19.7%). Some compounds, such as geranyl butyrate and germacrene-D, were only detected in the fruit oil.

Essential oil of Chinese medicinal herb,Chenopodium ambrosioidesaerial parts was found to possess nematicidal activity against the root-knot nematodes,Meloidogyne incognita. The essential oil ofC. ambrosioideswas obtained by hydrodistillation and analyzed by gas chromatography-mass spectrometry (GC-MS). A total of 27 components of the essential oil were identified. The principal compounds inC. ambrosioidesessential oil were (Z)-ascaridole (27.27%),ρ-cymene (19.05%), isoascaridole (14.75%),α-pinene (6.33%) andα-terpinene (5.12%). Bioactivity-guided chromatographic separation of the essential oil on repeated silica gel columns led to isolate three volatile components ((Z)-ascaridole,ρ-cymene and isoascaridole) from the essential oil. The essential oil and (Z)-ascaridole exhibited strong nematicidal activity againstM. incognitawith LC50values of 49.55 μg/mL and 32.79 μg/mL, respectively.ρ-Cymene and isoascaridole also possessed nematicidal activity againstM. incognitawith LC50values of 435.89 μg/mL and 1323.51 μg/mL, respectively but weaker than the crude essential oil.
