This study investigated the chemical composition and in-vitro cytotoxic activities of the essential oil isolated from the leaf of Beilschmiedia erythrophloia. The essential oil was isolated using hydrodistillation in a Clevenger-type apparatus, and characterized by GC-FID and GC-MS. Fifty-five compounds were identified, representing 100% of the oil. The main components identified were β-caryophyllene (22.6%), α-humulene (21.9%), terpinen-4-ol (5.3%), cis-β-ocimene (5.1%), sabinene (5.0%) and limonene (4.5%). The anticancer activities of oil were evaluated. The results showed that the oil exhibited cytotoxic activity against human oral, liver, lung, colon, melanoma, and leukemic cancer cells.

This study investigated the chemical composition and in vitro anticancer activities of the essential oil isolated from the leaf of Neolitsea variabillima. The essential oil was isolated using hydrodistillation in a Clevenger-type apparatus, and characterized by GC-FID and GC-MS. Sixty-seven compounds were identified, representing 100% of the oil. The main components identified were trans-β-ocimene (13.4%), α-cadinol (10.5%), terpinen-4-ol (9.3%), τ-cadinol (9.2%), β-caryophyllene (8.8%), and sabinene (6.7%). The anticancer activities of oil were evaluated. The results showed that the oil exhibited cytotoxic activity against human oral, liver, lung, colon, melanoma, and leukemic cancer cells. The presence of β-caryophyllene, τ-cadinol, and α-cadinol significantly contributed to the anticancer activities of N. variabillima leaf oil.

The leaf essential oil of Chromolaena odorata L. (Chenopodiaceae) from Togo were steam-distilled, analyzed by GC and GC-MS for chemical composition and investigated in vitro for its potential cytotoxic activity on human epidermic cell line HaCat. The chemical composition showed that the main constituents of essential oil sample were respectively ascaridole (51.12 %), p-cymene (19.88 %), neral (8.70%) and geraniol (7.55%). The in vitro cytotoxicity bioassays on human cell line HaCaT revealed moderate toxicity level of C. ambrosioides essential oil IC50 with 700 μL.mL-1. Pure commercial neral standard showed high toxicity with IC50 value of 100 μL.mL-1). Conversely, pure ascaridole p-cymene and geraniol standards appeared almost non-toxic (IC50 >1000 μL.mL-1), proving the major role played by neral in the overall toxicity showed by the C. ambrosiodes oil sample tested in this work.

The leaf essential oil of Ocotea tonduzii from Monteverde, Costa Rica has been obtained by hydrodistillation and analyzed by GC-MS. The principal constituents of O. tonduzii leaf oil were the monoterpenes α-pinene (41.4%) and pinene (25.1%) and the sesquiterpenes α-humulene (6.9%), β-caryophyllene (5.8%), and germacrene D (3.8%). O. tonduzii leaf oil was notably cytotoxic on MCF-7, MDA-MB-231, MDA-MB-468, and UACC-257 cells in vitro. The major essential oil components showed cytotoxic activities comparable to doxorubicin ( LC50, 20–70 μg/mL).

Rhododendron anthopogon D. Don., a small compact Himalayan shrub growing in Nepal, is a known medicinal plant used to treat sore throat, colds, blood disorders, bone disease, potato allergies, and vomiting, and to relieve liver disorders, headaches and back pain. The present study investigated the chemical composition and bioactivities of the leaf essential oil from R. anthopogon from Dhankuta, Nepal. The essential oil from leaves was obtained by hydrodistillation and a detailed chemical analysis was conducted by gas chromatography – mass spectrometry (GC-MS). The enantiomeric distribution of monoterpenoid components was determined using chiral gas chromatography and represents the first chiral examination of R. anthopogon essential oil. The essential oil was screened for antimicrobial activity using the microbroth dilution test, and for cytotoxic activity against MCF-7, MDA-MB-231, and 5637 using the MTT assay. A total of 70 volatile components were identified from the essential oil. The major components were α-pinene (21.5%), δ-cadinene (13.8%), β-pinene (9.5%), limonene (5.9%), δ-amorphene (4.6%), α-muurolene (4.5%), and ( E)-caryophyllene (3.2%) with other minor constituents (< 3%). The essential oil showed marginal antibacterial and cytotoxic activities, but no antifungal effects.

The present study aimed to determine the antimicrobial activity and chemical composition of leaves-extracted essential oil of Leoheo domatiophorus Chaowasku, D.T. Ngo and H.T. Le (L. domatiophorus), including antibacterial, antimycotic, antitrichomonas and antiviral effects. The essential oil was obtained using hydrodistillation, with an average yield of 0.34 ± 0.01% (v/w, dry leaves). There were 52 constituents as identified by GC/MS with available authentic standards, representing 96.74% of the entire leaves oil. The essential oil was comprised of three main components, namely viridiflorene (16.47%), (-)-δ-cadinene (15.58%) and γ-muurolene (8.00%). The oil showed good antimicrobial activities against several species: Gram-positive strains: Staphylococcus aureus (two strains) and Enterococcus faecalis, with Minimum Inhibitory Concentration (MIC) and Minimum Lethal Concentration (MLC) values from 0.25 to 1% (v/v); Gram-negative strains such as Escherichia coli (two strains), Pseudomonas aeruginosa (two strains) and Klebsiella pneumoniae, with MIC and MLC values between 2% and 8% (v/v); and finally Candida species, having MIC and MLC between 0.12 and 4% (v/v).Antitrichomonas activity of the oil was also undertaken, showing IC50, IC90 and MLC values of 0.008%, 0.016% and 0.03% (v/v), respectively, after 48h of incubation. The essential oil resultedin being completely ineffective against tested viruses, ssRNA+ (HIV-1, YFV, BVDV, Sb-1, CV-B4), ssRNA- (hRSVA2, VSV), dsRNA (Reo-1), and dsDNA (HSV-1, VV) viruses with EC50 values over 100 µg/mL. This is the first, yet comprehensive, scientific report about the chemical composition and pharmacological properties of the essential oil in L. domatiophorus.

The chemical composition of the essential oil obtained from the aerial parts of Cleome serrata by hydrodistillation was analyzed by employing GC-FID, GC-MS and RI. Fourteen compounds comprising 90.4% of the total oil composition were characterized. The main components identified were ( Z)-phytol (53.0%) and di(2-ethylhexyl)-phthalate (DEHP) (14.7%). The oil was evaluated for its in vitro antimicrobial activities against nine pathogenic microorganisms using the filter paper disc diffusion method. Moderate antimicrobial activity was observed against five of the pathogens assayed. In addition, the essential oil was tested against the sweet potato weevil, Cylas formicarius elegantulus. Strong knockdown insecticidal activity was observed.

The chemical composition and in vitro anti-inflammatory, antioxidant and antimicrobial activities of the leaf essential oil of Machilus konishii has been investigated. The essential oil was isolated using hydrodistillation in a Clevenger-type apparatus, and characterized by GC–FID and GC–MS. Sixty-six compounds were identified, representing 100% of the oil. The main components identified were α-pinene (33.9%), β-pinene (13.9%), and thymol (12.0%). The leaf oil was able to reduce nitric oxide production by lipopolysaccharide-activated murine macrophages RAW 264.7 without reducing the cell viability. In addition, the leaf oil showed strong antioxidant and antimicrobial activities. The major ingredient of the oil that was responsible for the anti-inflammatory, antioxidant and antimicrobial activities was thymol.

The chemical composition of the hydrodistilled leaf essential oil from Pulicaria stephanocarpa Balf Fil was determined by GC-MS analysis, and its antimicrobial, antioxidant and anticholinesterase (AChE) activities were evaluated. Eighty-three compounds were identified representing 97.2% of the total oil. ( E)-Caryophyllene 13.4%, ( E)-nerolidol 8.5%, caryophyllene oxide 8.5%, α-cadinol 8.2% spathulenol 6.8% and τ-cadinol 4.7%, were the main components. Antimicrobial activity of the oil, evaluated using the disc diffusion and broth dilution methods, demonstrated the highest susceptibility on Gram-positive bacteria and Candida albicans. The free radical scavenging ability of the oil was assessed by the DPPH assay to show antiradical activity with IC50 of 330 μg/mL. Moreover, the oil revealed an AChE inhibitory activity of 47% at a concentration of 200 μg/mL using Ellman's method.
