Background: Lepidium vesicarium (Cruciferae), one of the important medicinal plants with a long history of medicinal use. The current study was designed to evaluate the free radical scavenging and antimicrobial activities of the L. vesicarium EO as one of the Iranian plant species. Methods: The compositions of the EO from the aerial parts of L. vesicarium were analyzed by GC-MS and GC-FID. Furthermore, anti-oxidant and anti-microbial potentials were investigated via DPPH reagent and disk diffusion procedure, respectively. Results: A total of 18 compounds amounting 97.70% of the oil have been identified, while Benzyl cyanide (43.94%), Isothio cyanic acid (22.69%) and Benzyl isothio cyanate (20.69%) were the main constituents. The EO showed no activity against the free radicals and studied microbial strains (gram positive and gram negative and also fungi species). Conclusion: On the whole, the presence of cyanide derivatives in studied EO revealed the rational use of this plant in medicine. Comparing with other genesis of Lepidium, anti-oxidant and anti -microbial properties of L. vesicarium essential oil were not noticeable.

Background: The essential oil from the Acantholimon genus have been an integral part of the traditional food additive in Middle East. Most of the plants in Acantholimon genus have not been studied scientifically. The aim of this study is to investigate the chemical composition, antibacterial, insecticidal and anti-oxidant activities of three Acantholimon species including Acantholimon atropatanum, A. gilliatii and A. tragacanthium. Method: The essential oils of the aerial parts were extracted by hydrodistillation. Chemical constitutions were identified by gas chromatography- mass spectroscopy technique, also their toxicities were assessed against the two important grain products pests, Oryzeaphilus mercator and Tribolium castaneum. Antibacterial activity was assessed against the three foodborne bacteria that include Escherichia coli, Pseudomonas aeruginosa and Staphylococcus aureus based on the disc diffusion assay. Free-radical-scavenging property was identified based on 1, 1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging activity. Results: 2-hexahydrofarnesyl acetone was the main compound in A. gilliatii and A. tragacanthium, whilst farnesyl acetone, heptacosane and germacrene D were the principal components of A. atropatanum essential oil. These oils exhibited 40-90% mortality of O. mercator and/or T. castaneum at a dose of 12 μl/l air after 48h of exposure, and exhibited significant free-radicalscavenging property (RC50 = 3.7 × 10-3 - 8.3 × 10-3 mg/ml). The oils of A. tragacanthium and A. gilliatii showed a weaker antibacterial activity compared to A. atropatanum. Conclusion: A. atropatanum, A. gilliatii and A. tragacanthium essential oils had significant insecticidal and anti-oxidant properties. They also showed week to moderate antibacterial activity against P. aeruginosa and S. aureus.

Main Components

The essential oils from Foeniculum vulgare commercial aerial parts and fruits were isolated by hydrodistillation, with different distillation times (30 min, 1 h, 2 h and 3 h), and analyzed by GC and GC-MS. The antioxidant ability was estimated using four distinct methods. Antibacterial activity was determined by the agar diffusion method. Remarkable differences, and worrying from the quality and safety point of view, were detected in the essential oils. trans-Anethole (31-36%), α-pinene (14-20%) and limonene (11-13%) were the main components of the essentials oil isolated from F. vulgare dried aerial parts, whereas methyl chavicol (= estragole) (79-88%) was dominant in the fruit oils. With the DPPH method the plant oils showed better antioxidant activity than the fruits oils. With the TBARS method and at higher concentrations, fennel essential oils showed a pro-oxidant activity. None of the oils showed a hydroxyl radical scavenging capacity >50%, but they showed an ability to inhibit 5-lipoxygenase. The essential oils showed a very low antimicrobial activity. In general, the essential oils isolated during 2 h were as effective, from the biological activity point of view, as those isolated during 3 h.

Abstract Background Asparagus flagellaris leaves are ethnomedicinally used to treat syphilis, gonorrhea and other sexually transmitted diseases (STDs), with no reports on the volatile constituents. This study was aimed to quantitatively and qualitatively characterise the composition of essential oil, evaluates the free radical scavenging and antimicrobial capacity of the essential oil. Methods The essential oil was isolated by hydrodistillation method using all-glass Clevenger-type apparatus, while the identification and quantification of constituents were performed by gas chromatography-mass spectrometry (GC-MS) technique. The antioxidant activity on 2, 2-diphenyl-1-picrylhydrazyl (DPPH) was evaluated and the oil was also tested against 10 strains of microorganisms consisting of 6 bacteria: Escherichia coli, Salmonella typhi, Klebsiella pneumonia, Pseudomonas aeruginosa, Staphylococcus aureus and Bacillus subtilis and 4 fungi: Candida albicans, Penicillium notatum, Aspergillus niger and Rhizopus spp. using broth dilution and surface plate methods, respectively. Results A pale yellow essential oil with a characteristic scent was obtained, with a yield of 0.80% (w/w). A total of 28 compounds accounting for 97.41% of the total oil contents were identified. The oil was predominated by Thymol and its derivatives, accounting for 57.48%. The most abundance (% area) constituents of the essential oil were 5-Thymyl tiglate (18.49%), Thymyl-2-methyl butyrate (17.34%), Thymol hydroquinone dimethyl ether (10.52%), Thymol methyl ether (9.42%) and 5-Propyl-1, 3-benzodioxole (4.59%). The essential oil showed a significant free radical scavenging activity compared to the standard antioxidant drugs used in this study, with % inhibition varying from 88.06 ± 0.0001 to 93.05 ± 0.0006. The leaf essential oil exhibited antimicrobial activity on all the tested organisms at 500–125 μg/mL, with an 18–10 mm inhibitory zone. Conclusion The leaf essential oil of A. flagellaris contains notable chemical compounds responsible for its antioxidant and antimicrobial activities.

AbstractThe commercially processedThe phytochemical analysis showed that the extract contained flavonoids, terpenoids, glycosides, tannins and saponins. In the acetic acid-induced writhing test, the extract significantly reduced the number of writhes at 100 and 200 mg/kg but not so much at 50 mg/kg. In the formalin-induced paw lick test, the effect was similar to that of the acetic writhing test. The analgesic effects were comparable to that of indomethacin used at 10 mg/kg. In the anti-inflammatory test, the extract reduced the formation of oedema especially at a dose of 200 mg/kg. In the anti-oxidant test, the extract was found to possess a free radical-scavenging property and is concentration related.The use of this extract for medicinal and nutritional purposes may have thus been justified; however, caution must be exercised in its use to prevent the toxic effect.

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.
