Hydro-distillated essential oils (EO) antioxidant activity of three endemic medicinal plants of Iran namely, Heracleum lasiopetalum Boiss., Kelussia odoratissima Mozaff., and Ferulago angulata (Schlecht.) Boiss were studied. The results indicated that the major components of the EOs were 2-ethylhexyl acetate (34.5%), n-octanol (6.5%), and hexanol (5.1%) for H. lasiopetalum fruits; Z-?-ocimene (20.5), ?-pinene (11.6%), and ?-phellandrene (9.3) for F. angulata aerial parts; ?-pinene (20.1%), 1,8-cineole (18.2%), and Zligustilide (15.5%) for K. odoratissima aerial parts. The three EOs having high antioxidant activity could be used as an alternative preservative instead of synthetic ones in food industry. DOI: http://dx.doi.org/10.3329/bjb.v42i2.18038 Bangladesh J.

Two Populations

The fresh aerial parts of essential oils and headspace volatiles of two populations of Athamanta turbith ssp. haynaldii were analyzed in detail by GC and GC/MS analyses. In headspace samples, 32 compounds were identified, representing 98.4% and 98.8% of the total volatiles and were dominated by hydrocarbon sesquiterpenes, representing over 60% of both. Germacrene D was the major component, followed by terpinolene and myristicin. The essential oils of A. turbith consisted mainly of phenylpropene compounds with myristicin being the major compound. Fifty two compounds were identified in the oil isolated from Perućac and 57 from Kremna, accounting for 99.0% and 99.6% of total detectable components, with myristicin (52.3% and 50.8%, respectively) being the major component. In both samples, myristicin, germacrene D and δ-cadinene make up over 78% of the total oil composition. Antioxidant activity was measured using four different assays: DPPH, ABTS, CUPRAC and TRP method. It was found that the essential oil showed low antioxidant capacities compared with standard antioxidant compounds.

Antioxidant And Antimicrobial Activities

The aerial parts of Аrtemisia annua L. were collected from Varzob, Rudaki, and Hisor regions of Tajikistan. The essential oil was obtained by hydrodistillation and analyzed by gas chromatography–mass spectrometry. The essential oils of aerial parts of А. annua were dominated by the monoterpenoids like camphor (32.5%-58.9%), 1,8-cineole (13.7%-17.8%), camphene (4.5%-8.4%), and α-pinene (1.9%-7.3%). Hierarchical cluster analysis of A. annua essential oils indicated the existence of 3 A. annua chemotypes: camphor/1,8-cineole, camphor, and artemisia ketone. The essential oils of А. annua show weak antioxidant activity and average antibacterial activity. In our opinion, the antibacterial activity of А. annua essential oils is related to the presence of 1,8-cineole. To our best knowledge, this is the first report concerning the chemical composition, chemotypic variation, antioxidant, and antimicrobial activities of the essential oils obtained from the aerial parts of А. annua, growing wild in Tajikistan.

Some aspects of the chemical composition were studied in extracts of unexplored Phemeranthus confertiflorus L, an alien plant collected from Bucharest delta. 16 polyphenols and 10 short-chain organic acids were analysed and quantified by capillary electrophoresis in Phemeranthus extracts and antioxidant activity was investigated. The results obtained could promote Phemeranthus as an eligible plant with potential in food industry and for human health, because of the high antioxidant activity, high content of flavonoids (naringenin, rutin, daidzin) and lactic acid.

Background: The use of essential oils is receiving increasing attention worldwide, as these oils are good sources of several bioactive compounds. Nowadays essential oils are preferred over synthetic preservatives thanks to their antioxidant and antimicrobial properties. Several studies highlight the beneficial effect of essential oils extracted from medicinal plants to cure human diseases such as hypertension, diabetes, or obesity. However, to preserve their bioactivity, the use of appropriate extraction technologies is required. Method: The present review aims to describe the studies published so far on the essential oils focusing on their sources and chemical composition, the technologies used for their recovery and their application as antioxidants in food products. Results: The review has been structured in three parts. In the first part, the main compounds present in essential oils extracted from medicinal plants have been listed and described. In the second part, the most important technologies used for extraction and distillation, have been presented. In detail, conventional methods have been described and compared with innovative and green technologies. Finally, in the last part, the studies related to the application of essential oils as antioxidants in food products have been reviewed and the main findings discussed in detail. Conclusions: In summary, an overview of the aforementioned subjects is presented by discussing the results of the most recent published studies.

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.

Mistletoe Extracts

The content of plant secondary metabolites is not stable, and factors such as the region/location effect and seasonal variations have an impact on their chemical composition, especially in parasitic plants. Research in this area is an important step in the development of quality parameter standards of medicinal plants and their finished products. The effects of the time and place of harvest and the host tree species on the chemical composition and antioxidant activity of mistletoe extracts were investigated. Statistical tools were used to evaluate the results of the spectrophotometric and LC-ESI-MS/MS studies of the phenolic composition and antioxidant activity. The investigations indicate that the qualitative and quantitative composition, influencing the biological activity of mistletoe extracts, largely depends on the origin of the plant. The mistletoe extracts exhibited a rich phenol profile and high antioxidant activity. The chemometric analysis indicated that mistletoe collected from conifers (Viscum abietis and Viscum austriacum) had the most advantageous chemical composition and antioxidant activity. Moreover, the chemical profile and biological activity of the plant material were closely related to the climatic conditions and location of the harvested plant. Higher levels of phenolic compounds and high antioxidant activity were found in extracts obtained from plant material collected in cold weather with the presence of snow and less sunshine (autumn–winter period).
