Of particular interest, the higher yielding type B specimens, found in a significant geographically confined area, are diploid and the lower yielding specimens found elsewhere are tetraploid. diploid (2n=2x=24) potato species, Solanum bulbocastanum Dun. In this regard, medicinal usage modalities often involved ritualistic smoking ceremonies (smudging), heating bundles of leaves to produce intact volatiles, such as Eremophila bignoniiflora, or alternatively, topical treatments using lipophilic volatile and fixed components extracted into animal fats. Other novel results include generally poor activity from E. duttonii and E. sturtii essential oils and G. parviflora solvent extracts. (Myoporaceae): evidence for three chemotypes. 2020 Aug 13;126(3):363-376. doi: 10.1093/aob/mcaa107. The species is hermaphrodite (has both male and female organs). Journal of essential oil-bearing plants JEOP. Impact of genome duplication on secondary metabolite composition in non-cultivated species: a systematic meta-analysis. Our results suggest that polyploidization as a strategy to enhance metabolite production cannot be generalized. Subsequent analysis since that time has revealed at least 4 other chemotypes in New South Wales: type A, made up of isomenthone/menthone with a yield of 4-7% of wet leaves ; type B, made up of karahanaenone with a yield of 0.5-5%; type C, made up of various monoterpenes and monoterpenols including borneol and fenchol, with a yield of 0.2-0.7%; and type D, made up of various monoterpenes such as α-pinene, sabinene and limonene, with a yield of 0.0-0.2%. Use in horticulture. For example, the Adnyamathanha people used Varti-varka (Eremophila longifolia) in burial ceremonies and in initiation ceremonies. Lack of superiority may be attributed to the time required for adjustment, adaptation and evolution after the genomic shock induced by polyploidization, as well as the fact that an optimum ploidy level for each species may be crucial. Similarly, no significant differences were found among genotypes both for measures of gas and for chlorophyll fluorescence, except for non-photochemical quenching (NPQ). (Pittosporaceae), Callitris spp. The heterogeneous nature of chromosomes along with a high disparity index value reveal its advanced nature, whereas a high TF% value indicates its primitiveness. 5, 581-586, 1993) Eremophila longifolia. Epub 2013 Apr 4. Br.) In Europe, it is increasingly cultivated for its ornamental flowers, as well as for use in aromatherapy and traditional herbal medicine due to its broad spectrum of biological activities. Volatile oils of Eremophila longifolia F. Muell. From Petri Dish to Patient: Bioavailability Estimation and Mechanism of Action for Antimicrobial and Immunomodulatory Natural Products. (Rutaceae), were also used in a similar manner and are further explored herein. Leaf specimens of Eremophila longifolia were collected from western New South Wales, Australia. All rights reserved. Epub 2014 May 27. Steroidal saponins content revealed superiority of some tetraploids with respect to the diploid parent, suggesting perturbations in the mechanism regulating the biosynthesis of such compounds following polyploidization. Previous studies have demonstrated that the widely distributed desert plant Eremophila longifolia has at least six geographically defined essential oil chemotypes. The focus of the present study is to extend and enhance information concerning known chemotypes and to investigate the involvement of cell nuclei ploidy in this variation. The focus of the present study is to extend and enhance information concerning known chemotypes and to investigate the involvement of cell nuclei ploidy in this variation. Some chemotypes of Eremophila longifolia yield a much higher quantity of essential oil than plants typically used in smoke therapy or ritualistic smoking ceremonies around the world. Informed by an ethnopharmacological approach, our research extends the range of species with potential therapeutic and commercial value and provides the basis for longer term government and private investment in partnership with Aboriginal communities in an emerging health care industry addressing the imperatives of a globalized market while providing employment opportunities for Aboriginal people in marginalized regional communities. Aboriginal medicinal plant knowledge is a source of information that can guide the search for novel antimicrobial agents in the laboratory. eremanthus erythropappus branch/leaf oil: eremophila longifolia leaf extract: ergocalciferol: ergosterol: ergothioneine: erica cinerea flower extract: erigeron canadensis flower extract: extrait de fleurs de vergerette du canada: eriobotrya japonica leaf extract: extrait de feuille de néflier du japon: eriobotrya japonica leaf protoplasts It was found that the total phenolic content, as well as the radical scavenging activity of residual water remaining after hydrodistillation of G. macrorrhizum, is related to the plant ploidy level. Singab AN, Youssef FS, Ashour ML, Wink M. J Pharm Pharmacol. A positive result consistent with the literature was seen for a G. parviflora (chemotype 3) essential oil and so it was subjected to TLC bioautography to identify the active constituents. Australian Aboriginal phytotherapies: Antimicrobial activity and applications (B.Sc.(Hons.) Find NCBI SARS-CoV-2 literature, sequence, and clinical content: https://www.ncbi.nlm.nih.gov/sars-cov-2/. Clipboard, Search History, and several other advanced features are temporarily unavailable. COVID-19 is an emerging, rapidly evolving situation. 2010 Sep;71(13):1521-7. doi: 10.1016/j.phytochem.2010.06.006. As it was present with terpinen-4-ol, it was assayed for interactions with this compound and found to have at least an additive effect in preliminary antimicrobial screenings. Suitable pH: acid, neutral and basic (alkaline) soils. Smith J, Tucker D, Alter D, Watson K, Jones G. Phytochemistry. The essential oil composition, however, clearly depends on environmental factors. National Center for Biotechnology Information, Unable to load your collection due to an error, Unable to load your delegates due to an error. Join ResearchGate to find the people and research you need to help your work. These range from those exhibiting exceptionally high oil yields to those yielding no oil at all. In the current study, genifuranal was observed in trace amount in the condensates produced by simulated smoking of E. freelingii, and new and as-yet unidentified, smoke derivatives were also observed. Intraspecific variation in essential oil composition of Eremophila longifolia F. Muell. (J. Essent. J Ethnopharmacol. Reducing the extremely high incidence of preventable medical-errors in hospitals. Previously described high yielding essential oil chemotypes were also characterised in terms of diploidy. Two major constituents of the essential oil such as linalool and 1,8-cineole was increased 13 %and 77 %respectively, in the tetraploids than the diploid plants. (Myoporaceae) leaves were obtained by hydrodistillation and analysed using GC–MS. Copyright © 2014 Elsevier Ltd. All rights reserved. Customary use involves smoldering the leaves over hot embers of a fire to produce an acrid smoke, believed to have therapeutic effects broadly consistent with antimicrobial, antifungal and anti-inflammatory capacity. Furthermore, the previously described derivative 'genifuranal', produced in abundance in such condensates from E. longifolia, was reduced to the corresponding alcohol and the antimicrobial activity determined. Res. This study demonstrated in tetraploid basil revealed significant increases in dry and fresh weight, leaf wide and thickness, stem diameter and number of branches per plant increase in ploidy level causes significant decrease in leaf long, cluster number, seed germination percent and rate as compared with diploid parent. Eremophilas have not often been cultivated in the past, although some species, including Eremophila maculata are well known.
