Basil essential oil (BEO) contains a wide range of chemical compounds whose content may vary depending on chemotypes, environmental conditions, agronomic techniques and particularly the origin of the plant. In our present study, essential oils (EOs) were isolated by hydrodistillation method from dry herbs of three basil cultivars and analyzed by GC-FID and GC-MS. Two of the tested cultivars belong to sweet basil group (B1 and B2) while the third one was large leafed ʽGenovese’ basil (B3). EO content in the dry herb was 0.65%, 0.41% and 0.62% respectively. The main classes of compounds of B1EO and B3EO were sesquiterpene hydrocarbons (38.39% and 37.95%), oxygenated monoterpenes (25.44% and 28.04%) and phenylpropanoids (17.43% and 15.71%). The main constituents of both EOs were monoterpene alcohol linalool (13.68% and 15.38%), phenoyl derivate eugenol (10.83% and 8.97%) and sesquiterpene hydrocarbon α-bergamotene (8.12% and 9.25%). In both EOs, epi-bicyclosesquiphellandrene was detected in considerable amount (7.03% and 8.07%). The most abundant compound classes in B2EO were oxygenated monoterpenes (52.07%), sesquiterpene hydrocarbons (24.27%) and phenylpropanoids (10.95%). Linalool was the dominant compound (40.97%), followed by epi-bicyclosesquiphellandrene (8.70%) and methyl chavicol (7.92%). The results showed complex chemical composition of BEOs and pointed out the presence of biologically active compounds of importance for different branches of the pharmaceutical, chemical and food industry. Although there are differences in the chemical composition of the BEOs, the obtained results show that all of the tested cultivars are rich in compounds which are responsible for biological activities.

Abstract The composition of essential oils of Leutea glaucopruinosa (Rech.f.) Akhani & Salimian comb, nov., and Zeravschania (Boiss. & Hausskn.) Salimian & Akhani comb. nov. were analysed by GC-MS. 49 compounds are identified in the former and 33 compounds in the latter, comprising a total of 76 compounds in both species. Both species were originally described under Peucedanum, which are transferred in this paper into Leutea and Zeravschania, respectively. The chemical compounds of the essential oils show that there are only seven common compounds between two species. The major compounds of L. glaucopruinosa are mostly monoterpene hydrocarbons and oxygenated monoterpenes, in which α-pinene (31.5%), sabinene (9.7%), β-pinene (9.2%), exo-fenchyl acetate (4.5%) are dominant. In Z. pastinacifolia sesquiterpene hydrocarbons and phenylpropanoids dominate with β-bisabolene (37.3%), 3,1-butyl-1.2-dimethoxy benzene (14.9%), 10,11-dimethylbicyclo[6.3.0]undec-(8)-en-9-one (12.9%), 4-t-butyl-1,2-dimethoxy benzene (6.8%), (E)-asarone (5.1%) and elemicine (4.1%) as major compounds.

In this work, essential oils (EOs) and hydrolates (Hys) of Rosmarinus officinalis L. and Lavandula angustifolia Mill., grown in Tuscany (Italy), were studied to describe their chemical composition and biological activities. The aromatic profile of the EOs liquid phase was carried out by gas chromatography–mass spectrometry (GC–MS), while the volatile composition of vapor phase EOs and Hys was performed by headspace (HS)/GC–MS. The obtained results show that monoterpene hydrocarbons (71.5% and 89.5%) were the main compounds, followed by oxygenated monoterpenes (26.0% and 10.5%) in the liquid and vapor phase of R. officinalis EO, respectively. The oxygenated monoterpenes were the main components of L. angustifolia EO, reaching 86.9% in the liquid phase and 53.7% in the vapor phase. Regarding Hys, they consisted only of oxygenated monoterpenes, and 1,8-cineole (56.2%) and linalool (42.9%), were the main components of R. officinalis and L. officinalis Hys, respectively. Their cytotoxicity was investigated on an SHSY5Y neuroblastoma cell line by thiazolyl blue tetrazolium bromide (MTT) test, showing a notable effect of the EOs with a time-independent manner of activity and half maximal effective concentration (EC50) values quite similar for the two plant species (from 0.05% to 0.06% v/v for the three time points evaluated). A measurable activity of Hys was also obtained although with higher EC50 values. The antibacterial activity against Escherichia coli ATCC® 25922, Pseudomonas fluorescens ATCC® 13525, Acinetobacter bohemicus DSM 102855 as Gram-negative bacteria and Kocuria marina DSM 16420, Bacillus cereus ATCC® 10876 as Gram-positive bacteria, was evaluated by the agar disk-diffusion method and the VPT (vapor phase test) to determinate the MIC (minimal inhibitory concentration) and the MBC (minimal bactericidal concentration) values. Both EOs possessed a high activity against all the bacterial strains with MIC values ranging from 0.19% to 3.13% v/v. Unlike EOs, Hys did not show an inhibition of the bacterial growth at the tested concentrations. Furthermore, antioxidant power was measured by 2,2’-azino-bis (3-ethylbenzothiazoline-6-sulfonic acid) diammonium salt-based (ABTS•+) and the 2,2-diphenyl-1-picrylhydrazyl (DPPH) assays, showing a remarkable ability to reduce radicals by both EOs; Hys were slightly less active. The findings highlighted that R. officinalis and L. angustifolia EOs and Hys have a chemical composition rich in bioactive molecules, which can exert different biological activities.

ABSTRACT: The Annonaceae family consists of ~135 genera with diverse species and a large number of chemical compounds arising from the secondary metabolism. However, the chemical composition of the essential oil of several species of the family such as Cardiopetalum calophyllum has not been completely determined. In this study, the essential oils extracted from the leaves, flowers, and fruits of C. calophyllum , collected in typical areas of the Cerrado of Goiás, were characterized. The essential oil was extracted by hydrodistillation for 4h using a Clevenger apparatus. The chemical analysis was carried out by gas chromatography-mass spectrometry (GC-MS), and the constituents were identified by comparing the spectra and retention index obtained with those available in the literature. Twenty three compounds were identified in the essential oil of leaves; the oxygenated sesquiterpene, spathulenol (28.78%), was the major compound. Twenty five compounds were identified in the flowers, mainly comprising sesquiterpene hydrocarbons, germacrene-D (37.03%) and germacrene-B (13.72%). Seventeen compounds were reported in fruits, mainly comprising sesquiterpene hydrocarbons, germacrene-D (28.19%) and germacrene-B (20.90%), and an oxygenated sesquiterpene, spathulenol (11.53%). This is the first report on the chemical composition of the essential oils from leaves, flowers, and fruits of C. calophyllum.

Plantago major L. in Vietnam was investigated for its chemical composition and also evaluated the biological activities against enzyme α- glucosidase and free radicals activities. The powder mixture of dried leave and roots of this species was extracted separately by three solvents: dichloromethane, water, water:alcohol (50:50, v:v). The chemical composition of dichloromethane extract was analyzed by GC-MS system to identify eighteen components, out of which eight biologically active compounds viz. 5-hydroxymethylfurfural, n-hecxadecanoic acid, 9,12-octadecadienoic acid (Z,Z)-methyl ester, allogibberic acid, β-tocopherol, campesterol, γ-sitosterol, lup-20(29)-en-3-ol and friedenlan-3-one were presented. The concentration of radical scavenging activity DPPH expressed by IC50 for water, water:alcohol (50:50, v:v) and dichloromethane with 208.7, 89.3 and 62.05 μg/mL, respectively. The dichloromethane, water and water:alcohol (50:50, v:v) extract of Plantago major exhibited α-glucosidase inhibitory activity with IC50 values of 116.4, 302.7, 195.9 μg/mL, respectively, which was comparable with acarbose (98.4 μg/mL). Plantago major L. in Vietnam may be effective inhibitors as the antidiabetic candidate and helpful to reduce the postprandial glucose levels.
