AbstractThe essential oil of Ducrosia ismaelis Asch. (Apiaceae) that grows wild in Saudi Arabia was investigated utilizing gas chromatography (GC), and gas chromatography-mass spectrometry. Fifty constituents were characterized, representing 96.1% of the total oil. The D. ismaelis essential oil (DIEO) was distinguished by a high composition of oxygenated monoterpenes (51.6%). Decanal (40.6%), α-pinene (15.1%) and dodecanal (13.7%) were the fundamental components. Additionally, DIEO was evaluated for its cytotoxic, antibacterial, antifungal and antioxidant activities. DIEO revealed a great cytotoxic effectiveness against the tested cancer cell lines with IC50 values between 66.2 and 137.3 μg/mL particularly against MCF-7 cancer cells. Furthermore, the induction of apoptosis against MCF-7 cells has been asserted using staining assay (annexin VFITC and/or propidium iodide (PI) dyes) and flow cytometry technique. The DIEO possessed a strong antimicrobial activity against Gram-positive bacterial and fungal strains with MIC-values between 0.07 and 0.31 mg/ml. The values of MBC or MFC were almost once higher than those of MIC’s. Moreover, the β-carotene-bleaching and DPPH free radical-scavenging tests showed that DIEO had a moderate activity (68%) as an antioxidant agent in decolouring of the β-carotene at 1.0 mg/mL and a moderate radical scavenging for DPPH (66 and 72%) at 0.50 and 1.0 mg/mL.

The constituents of the volatile oil of air-dried aerial parts of Mentha pulegium L. (Lamiaceae) plants wildly growing in Northwest Iran were analysed by GC/MS. 46 components were identified, comprising 96.6% of the essential oil. Monoterpenes (78.9%) were the main class of the identified components followed by a minor proportion of sesqui-<br />terpenes (11%). Oxygenated monoterpenes (75.3%) were the major subclass of volatile oil components with menthone (38.7%), menthol (11.3%), neomenthol (10.5%), and pulegone (6.8%) as major compounds. Sesquiterpene hydrocarbons (10.6%) were the highlighted subclass of 15 carbons sesquiterpenoidal compounds with (E)-caryophyllene (4.9%) and &beta;-cubebene (2.5%) as their principle representatives. Furthermore, menthyl acetate (C<sub>12</sub> acetylated monoterpene derived compound) was contained considerable amounts (5.2%) in the essential oil. In total, volatile oil composition of M. pulegium L. plants studied in the present experiment was characterised as a new menthone type with appreciable amounts of menthol and neomenthol, and it could be used as a potential source of these high value monoterpenes in pharmaceutical and food industries.

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.

Variations in the essential oil composition of aerial parts of pineapple weed (Chamomilla suaveolens (Pursh) Rydb.) growing wild in Estonia, were determined using GC/FID and GC/MS. Forty-four components were identified, representing over 90% of the total oil. Nine compounds have not been mentioned in the literature before. The principal biologically active compounds in C. suaveolens oils were (Z)-en-yne-dicycloether (17.0 – 40.7%), (E)-β-farnesene (19.5– 32.2%), geranyl isovaleriate (8.4 –18.4%), palmitic acid (0.3 – 9.4%) and myrcene (1.1 – 7.9%). The investigation seems to approve the benefit of using aerial parts of pineapple weed as the substitute for flowers.

AbstractTwo flavonoid aglycons, eight flavonoid glycosides, chlorogenic acid and syringin were isolated from aerial parts of Carthamus lanatus. Isorhamnetin 3-O-β-ᴅ-glucoside and chlorogenic acid were found for the first time in the genus Carthamus and respectively, quercimeritrin, astragalin, kaempferol 3-O-β-ᴅ-sophoroside and syringin in the species. The ethyl acetate fraction of the methanol extract exhibited a higher antioxidant activity than the butanol fraction measured by the α,α-diphenyl-β-picrazylhydrazyl (DPPH) free radical scavenging assay. Cytotoxicity and antioxidant activities of the main constituent, luteolin 7-O-β-D-glucoside, were evaluated.
