Kulyal, Poonam published the artcileVariable secondary metabolite profiles across cultivars of Curcuma longa and Curcuma aromatica, COA of Formula: C10H18O, the main research area is diarylheptanoid santolina alc Zingiberaceae essential oil; Curcuma aromatica Salisb; Curcuma longa L.; GC-MS; LC-MS; essential oil; metabolomics; secondary metabolites.

Curcuma spp. (Zingiberaceae) are used as a spice and coloring agent. Their rhizomes and essential oils are known for medicinal properties, besides their use in the flavoring and cosmetic industry. Most of these biol. activities were attributed to volatile and nonvolatile secondary metabolites present in the rhizomes of Curcuma spp. The metabolite variations among the species and even cultivars need to be established for optimized use of Curcuma spp. Objectives: We compared the phytochem. profiles of rhizomes and their essential oils to establish the variability among seven cultivars: five of Curcuma longa L. (Alleppey Supreme, Duggirala Red, Prathibha, Salem, Suguna) and two of C. aromatica Salisb. (Kasturi Araku, Kasturi Avidi). The GC-MS and LCMS-based analyses were employed to profile secondary metabolites of these selected cultivars. Rhizomes of Curcuma spp. were subjected to hydro-distillation to collect essential oil and analyzed by GC-MS. The methanol extracts of fresh rhizomes were subjected to LC-MS analyses. The compounds were identified by using the relevant MS library databases as many compounds as possible. The essential oil content of the cultivars was in the range of 0.74-1.62%. Several compounds were detected from the essential oils and rhizome extracts by GC-MS and LC-MS, resp. Of these, 28 compounds (13 from GCMS and 15 from LCMS) were common in all seven cultivars, e.g., α-thujene, and diarylheptanoids like curcumin. Furthermore, a total of 39 new compounds were identified from C. longa L. and/or C. aromatica Salisb., most of them being cultivar-specific. Of these compounds, 35 were detected by GC-MS analyses of essential oils, 1,2- cyclohexanediol, 1-methyl-4-(1-methylethyl)-, and santolina alc., to name a few. The other four compounds were detected by LC-MS of the methanolic extracts of the rhizomes, e.g., kaempferol-3,7-O-dimethyl ether and 5,7,8-trihydroxy-2′,5′- dimethoxy-3′,4′-methylene dioxyisoflavanone. We identified and recorded the variability in the metabolite profiles of essential oils and whole rhizome extracts from the seven cultivars of Curcuma longa L. and C. aromatica Salisb. As many as 39 new metabolites were detected in these seven Indian cultivars of Curcuma spp. Many of these compounds have health benefits.

Rozwalka, Luciane Cristina published the artcileChemical components of essential oils as a base to control two grape pathogens: Sphaceloma ampelinum and Pseudocercopora vitis, COA of Formula: C10H18O, the main research area is chem component essential oil Sphaceloma ampelinum Pseudocercopora vitis.

Anthracnose and grapevine leaf spot are the most important fungal diseases of fox grape in Brazil caused by Sphaceloma ampelinum and Pseudocercospora vitis, resp. Severe attacks of either diseases can affect the yield in the current and subsequent years. Synthetic fungicides are recommended to control these pathogens in the field but may be harmful to the environment and human health over time and select for fungicide-resistant pathogen populations. Among the new strategies for safe food production, free of pesticide residues, essential oils represent a promising tool to control plant pathogens. The objectives of this study were to evaluate the antifungal activity of the volatile compounds of 26 essential oils on germination of P. vitis and S. ampelinum and of their principal active compounds as bases for development of new technol. products. The essential oils of Cinnamomum zeylanicum and Cymbopogon citratus were fungitoxic to P. vitis and S. ampelinum, in vapor and liquid phases, completely inhibiting spore germination. The main compounds found in the essential oils studied were citral, geraniol, eugenol and isoeugenol. All of these, in vapor and liquid phases, were toxic to P. vitis, completely inhibiting spore germination. Citral, in the vapor phase, and citral, eugenol and isoeugenol in the liquid phase, were toxic to S. ampelinum, completely inhibiting spore germination.

Weisany, Weria published the artcileNano silver-encapsulation of Thymus daenensis and Anethum graveolens essential oils enhances antifungal potential against strawberry anthracnose, HPLC of Formula: 124-76-5, the main research area is Thymus Anethum Colletotrichum nanosilver essential oil antifungal.

Nanotechnol. is an eco-friendly strategy in managing plant diseases. In combination with existing practices nanotechnol. can enhance the protection of agricultural products and food. For example, essential oils (EOs) of thyme (Thymus daenensis L.) and dill (Anethum graveolens L.) have an antimicrobial potential and this potential may be enhanced by certain nanoparticle systems. Here we demonstrate that encapsulating EOs of thyme and dill in silver nanoparticles increases their fungicidal activity against Colletotrichum nymphaeae, causing anthracnose in many horticultural crops. Using GC-MS anal., we identified p-cymene, thymol, carvacrol and (E)-caryophyllene as the main EOs of thyme and limonene, cis-dihydrocarvone, cyclohexanon, and carvone as the main EOs of dill. When the EOs of the two sources were encapsulated in silver nanoparticles, synergistic effects against C. nymphaeae were observed, resulting in more than 80% inhibition of mycelium growth of C. nymphaeae. Moreover, conidia germination was suppressed by nano-encapsulated EOs. We also observed considerable morphol. changes in the fungal hyphae when nano-encapsulated EOs were applied. Our study demonstrates the potential of encapsulated EOs in controlling pathogens that can be very applicable as antifungal agents.

Weisany, Weria published the artcileEnhancement of the antifungal activity of thyme and dill essential oils against Colletotrichum nymphaeae by nano-encapsulation with copper NPs, Quality Control of 124-76-5, the main research area is Anethum Thymus leaf oil copper nanoparticle encapsulation antifungal Colletotrichum.

Nanotechnol. is a quickly growing field and have been actually used in a varied assortment of marketable products worldwide. Nanoencapsulation demonstrations the advantage of more efficient and targeted use of pesticides in an environmentally friendly way. Research and development in post-harvest nanotechnol. can help to preserve food freshness and quality and prevent diseases in a relatively safer way. In this regard, essential oils (EOs) represent promising agents for reducing food decay and development of pathogen microorganisms. The overall aim of the present study was to encapsulate Iranian thyme (Thymus daenensis L) and dill (Anethum graveolens L.) EOs in copper nanoparticles (NPs) and to evaluate their antifungal activity against the phytopathogen Colletotrichum nymphaeae. Encapsulation of thyme and dill EOs with copper NPs resulted effective in reducing the mycelium growth even by 90% after 9 days treatment. Furthermore a strong inhibitory effect on conidia germination of C. nymphaeae was observed SEM observations indicated that C. nymphaeae treated with EOs, copper NPs and encapsulated EOs, showed deformation in mycelial growth and hyphae twisting. In summary, these results showed that nano-encapsulation of EOs with NPs, using safe materials, increased the perspective of their effectiveness as new plant disease management strategies.

Becerra, Jaime-Andres published the artcileTechno-Economic Evaluation of d-Limonene and α-Pinene Separation from Citrus and Turpentine Oils, Quality Control of 124-76-5, the main research area is techno economic limonene alpha pinene Citrus turpentine oil.

The evaluation of the tech. and economic separation of the monoterpenes α-pinene and d-limonene from essential oils, carried out by computational simulation of the vacuum fractional distillation in continuous and batch mode from samples of turpentine and citrus oils, was developed using Aspen Plus software combined with estimations of operational expenses (OPEX) and capital expenses (CAPEX) based on the Guthrie method. The production of d-limonene and α-pinene with high purity from the essential oils is a tech. feasible process. From the economic point of view and based on the average annual import costs of turpentine and orange oils in Colombia, it was found that the selling prices of α-pinene and d-limonene obtained from the distillation module cost anal. depend on the daily production and can be minimized if essential oils are preliminary extracted from local industrial wastes.

Taktak, Nehad E. M. published the artcileNanoemulsions containing some plant essential oils as promising formulations against Culex pipiens (L.) larvae and their biochemical studies, Computed Properties of 124-76-5, the main research area is Culex larva essential oils nanoemulsions formulations larvicidal; Biochemical studies; Culex pipiens; Essential oils; GC/MS; Larvicidal activity; Nanoemulsions.

The chem. composition of cypress, lavender, lemon eucalyptus, and tea tree oils has been investigated using gas chromatog./mass spectrometry (GC/MS). These oils were tested for larvicidal activity against Culex pipiens alongside their nanoemulsions (NEs) and conventional emulsifiable concentrates (ECs). Oil-in-water (O/W) NEs preparation was based on a high-energy ultra-sonication technique. The effect of independent variables of preparation on the different outputs was studied using the response surface method to obtain the optimum preparation technique. The droplet sizes of prepared NEs were significantly different (71.67, 104.55, 211.07, and 70.67 for cypress, lavender, lemon eucalyptus, and Tea tree NEs, resp.). The zeta potentials of NEs were recorded to have a high neg. charge (-28.4, -22.2, -23.6, and – 22.3 mV for cypress, lavender, lemon eucalyptus, and tea tree NEs, resp.). The results showed that the tea tree oil has the most significant effect with LC50 = 60.02 and 57.10 mg/L after 24 and 48 h of exposure, resp. In comparison, cypress oil proved the lowest toxicity with LC50 values of 202.24 and 180.70 mg/L after 24 and 48 h, resp. However, lavender oil does not show any effect against larvae at tested concentrations In addition, pure oil exhibited the lowest larvicidal activity. However, the EC of all tested insecticides slightly improved the toxic action against the larvae. While the NEs showed significantly high toxicity compared to the EO and EC. An in vivo assessment of acetylcholine esterase (AChE), ATPase (ATPase), and gamma-aminobutyric acid transaminase (GABA-T) revealed that the NEs exhibited higher activity than the pure oils and ECs. This work describes these oils with potential use against C. pipiens larvae as eco-friendly products.

Verma, Ram Swaroop published the artcileEssential oil composition of the sub-aerial parts of eight species of Cymbopogon (Poaceae), Computed Properties of 124-76-5, the main research area is cymbopogon essential oil sub aerial pinane carane myrcane.

The genus Cymbopogon (Poaceae) comprised of many species of grasses that grow in tropical and subtropical regions around the world. Some of the com. important aromatic species of Cymbopogon are cultivated for the extraction of the essential oils from their aerial-parts. In spite of wide distribution and large scale cultivation, the essential oils of the sub-aerial parts (root/rhizome) of these species have not been systematically studied so far. In this study, the hydro-distilled essential oils from the sub-aerial parts of eight species, including a hybrid of Cymbopogon, namely C. flexuosus (Nees ex Steud.) W.Watson, C. khasianus (Hack.) Stapf ex Bor, C. pendulus Nees ex Steud., C. khasianus × C. pendulus, C. winterianus Jowitt ex Bor, C. martini (Roxb.) W.Watson, C. distans (Nees ex Steud.) W.Watson, and C. jwarancusa (Jones) Schult. and their varieties/chemotypes were analyzed by gas chromatog.-flame ionization detector (GC-FID) and gas chromatog.-mass spectrometry (GC-MS). A total of thirty-three terpene C-skeleton types (six monoterpene skeletons, twenty-seven sesquiterpene skeletons) were identified. A multivariate statistical comparison by principal component anal. and agglomerative hierarchical clustering grouped the examined essential oils in to four clusters (cluster I: geraniol, and piperitone/ geraniol chemotypes; cluster II: high elemol and low elemol chemotypes; cluster III: limonene chemotype; and cluster IV: 5-epl-7-epl-α-eudesmol/eudesmanediol/hinesol, and cis-p-menth-2-en-1-ol/trans-p-menth-2-en-1-ol/eudesmanediol chemotypes).

Hashemi, Seyed Mohammad Bagher published the artcileBasil seed gum edible films incorporated with Artemisia sieberi and Achillea santolina essential oils: Physical, antibacterial, and antioxidant properties, Application In Synthesis of 124-76-5, the main research area is Artemisia Achillea antibacterial antioxidant essential oil basil seed gum.

Active edible films were prepared by incorporating Artemisia sieberi and Achillea santolina essential oils (EOs) in basil seed gum (BSG) films. The results showed an increase in opacity, contact angel, and water vapor permeability of the films by the addition of EOs, whereas the moisture content, water absorption capacity, and water solubility declined. The presence of EOs significantly improved the DPPH and ABTS radical scavenging activities of BSG films. The agar diffusion disk method was carried out to evaluate the antibacterial activity of the films against Staphylococcus aureus, Bacillus cereus, Listeria monocytogenes, Shigella dysenteriae, Salmonella Typhi, and Pseudomonas aeruginosa. BSG film containing A. santolina + A. sieberi (1:2 volume/volume) demonstrated the highest antibacterial activity against the selected bacteria. It can be concluded that BSG film loaded with A. santolina + A. sieberi (1:2 volume/volume) EOs have the potential to be used as an active edible film and improve the shelf life of food products by delaying the oxidation and the microbial growth. Novelty impact statement : Active edible films were prepared by incorporation of Artemisia sieberi and Achillea santolina essential oils (EO) into basil seed gum (BSG) films. EOs significantly increased the opacity, water contact angel, and water vapor permeability of BSG films. Films incorporated with the mixture of EOs (A. santolina + A. sieberi (1:2 volume/volume)) showed the highest antibacterial and antioxidant activities. BSG films that contained these EOs have the potential to be used as active packaging to increase the shelf life of food products.
