MestreNova NMR spectroscopy TopSpin automatic analysis edible oil fatty acid composition iodine value.Ĭastejón D., Mateos-Aparicio I., Molero M.D., Cambero M.I., Herrera A. To demonstrate the applicability of this method, the fatty acid composition of extra virgin olive oils from various Spanish olive varieties (arbequina, cornicabra, hojiblanca, manzanilla, and picual) was determined by ¹H-NMR spectroscopy according to this protocol. Due to the fact that this protocol can be carried out at low field and that the complete process from sample preparation to printing the report only takes about 3 min, this approach is promising to become a fundamental technique for high-throughput screening. The objective of this work was to drive forward the automated analysis of the FAC by NMR. To achieve this, two scripts, which automatically analyze and interpret the spectral data, were developed. We describe the evaluation and optimization needed for the automated analysis of vegetable oils by low-field NMR to obtain the fatty acid composition (FAC). If this option is not selected, the layout template will only keep the properties.In this work, we introduce an NMR-based screening method for the fatty acid composition analysis of edible oils. If you check the ‘Apply Processing Template’ option, the layout template will keep also the processing used in the original spectrum. Another thing you can do is double click on any item to change any property and then save the changes.Īpply a layout template to any opened spectrum, just by following the menu “View/Layout Templates/Apply Template Document”: If you open again the template you will have by default the annotation and the logo on your screen. For example in the template above we have added an annotation and a logo and then clicked in the ‘Save’ button. In the same way, when the user opens or pastes a molecule and an image, they will also be automatically displayed in the corresponding location (with the original properties).Īlso note that our concept is designed to be extended to reports with more than one page, to allow for the placing of several spectra on the report (in this case 1H, 13C and HSQC): If you open a different 1D-NMR spectrum over this layout, it will be obtained in the corresponding location, with the corresponding processing and analysis features (multiplet analysis in this case) and also with the corresponding object properties, including all the relevant tables and reports: The picture below shows you the layout created previously: The layout template will keep all the properties of the objects (draws, annotations, spectra and molecules), the processing (optional) and the analysis features used in the original spectrum (‘peak picking’, ‘integrals’, ‘multiplets’ or cuttings). Please note that drag and drop also works in this instance. Once saved, a template can be easily opened by double clicking on the. To save the created layout as a template, just follow the menu ‘View/Layout Templates/Create Template Document’ and select the location of the new template. The picture below shows a 1H-NMR spectrum, with the corresponding molecular structure, multiplet report, images and the Parameters table: It is very easy to create a template with Mnova, just open a document and select the desired location and properties for the different objects present in it. This feature includes the capability to create templates with the location of the spectrum, molecular structure, images, tables and multiplet reports.
