Artemisia subviscosa Turcz. Ex Bess. is an endemic species of the Baikal region. It grow on the territory of the Barguzinsky region of the Republic of Buryatia. Raw materials for the study were collected during the expedition work in 2016. By the method of hydrodistillation the essential oils from the aerial parts and individual organs (inflorescences, leaves, stems) of the A. subviscosa was extract. The greatest yield of essential oil is registered in flowers (0.7%). The composition was determined by chromatography-mass spectrometry on an Agilent Packard HP 6890 gas chromatograph with a quadrupole mass spectrometer (HP MSD 5973N) as a detector. More than 70 components have been identified and it has been established that the composition of essential oils is represented by mono- and sesquiterpene compounds, the first predominantly accumulate in the inflorescences, the others – in leaves and stems and the aerial parts. The dominant components are santolina triene (2.9–33.1%), germacrene D (2.1–8.8%), β-selinene (6.4–9.3%), α-selinene (6.4–8.6%), α-bulnesene (1.9–2.7%), δ-cadinene (1.7–2.4%), caryophyllene oxide (2.1–9.9%), caryophyllene (11.6–17.5%), γ-muurolene (1.4–4.0%), aciphyllene (2.8–3.2%) , acyphyllic acid (4.5–10.5%), spathulenol (0.8–3.7%).

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.

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 essential oils of Blainvellea rhomboidea (Asteraceae) were obtained by hydrodistillation and analyzed by GC/MS and GC/FID. Initially, the essential oil from the aerial parts was investigated. From the 18 identified components, 5-indanol (14.5%) followed by p-cymen-8-ol (10.1%), β-caryophyllene (9.6%), caryophyllene oxide (9.6%), limonene (8.6%), terpinolene (7.8%), and spathulenol (7.7%) were the major constituents. The oil was tested against seven bacterial strains and the results showed significant antimicrobial activity. As a consequence, the essential oils from leaves and from flowers were analyzed separately. The major constituents of the leaf oil were terpinolene (21.2%), β-caryophyllene (19.2%), spathulenol (9.1%), caryophyllene oxide (7.4%), and bicyclogermacrene (7.1%), while the oil of the flowers contained terpinolene (28.1%), 5-indanol (16.3%), p-cymen-8-ol (15.3%) and limonene (14.7%) as prevalent compounds. The oils were tested against the same bacterial strains and the flower oil was the more active. These results indicated that the components of the essential oil from flowers seem to be responsible for the activity.

Abstract The purpose of our study was to compare the chemical compositions and antimicrobial and antioxidant activities of Pycnocycla spinosa and Pycnocycla flabellifolia essential oils. cis-Asarone (62.5%) and widdra-2,4(14)-diene (9%) were the main components of P. spinosa aerial part essential oil, while elemicin (60.1%) and caryophyllene oxide (9.8%) were the main components of P. spinosa seed essential oil. α-Phellandrene (25.5%), p-cymene (15.3%), and limonene (13.3%) were found in P. flabellifolia essential oil. The inhibition zone diameters for P. flabellifolia essential oil were significantly higher than for the two other essential oils from P. spinosa (p<0.05). In broth dilution assay (µL/mL), the sensitive microorganism to Pycnocycla sp. (P. spinosa, P. flabellifolia) was Aspergillus niger, followed by Candida albicans. In 2,2-diphenyl-1-picrylhydrazyl (DPPH) system, P. spinosa aerial parts essential oil (IC50=548 µg/mL) had higher antioxidant activity than that of two other essential oils.

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.

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
