Chemical Extraction and Composition Analysis of 25b Essential Oils For Pest Control




Pest Geek Podcast  show

Summary: Essential oils composition is very complex, in order to identify what chemical component actually control the pest with what mode of action requires an individual extraction and testing on a specific pest.<br> Answering which component has what mode of action Insecticidal, Antifeedant, Repellent, Oviposition Deterrent, Growth Regulatory And Antivector Activities on which pest still can not get answered.<br> <a href="http://www.pestgeekpodcast.com/?attachment_id=6078" rel="attachment wp-att-6078"></a><br> Chemical Extraction and Composition Analysis of 25b Essential Oils<br> <br> * Chemical Extraction and Composition Analysis Methods<br> * Capillary gas chromatography (GC)<br> * Gas Chromatography<br> * Mass Spectrometry (MS)<br> * Chemometric resolution<br> * Olfactometry and multidimensional gas chromatography<br> * Enantioselective capillary gas chromatography<br> * Stable isotope ratio mass spectrometry<br> * Hydrodistillation<br> * Purity Standards of 25b Essential Oils<br> <br> Adulteration of Essential Oils<br> <br> * Total ion chromatogram essential oils<br> <br> Extraction Methods of 25b Essential Oils<br> <br> * Hydro-distillation<br> * Microwave extraction<br> * CSE Cold solvent extraction<br> * ASE accelerated solvent extraction<br> * SFE supercritical fluid extraction<br> * SPME solid-phase microextraction<br> <br> Chemical Extraction and Composition Analysis Studies of 25b Essential Oils<br> The Extraction and Quantification of Limonene from Citrus Rinds Using GC/MS<br><br> <a href="https://www.perkinelmer.com/PDFs/downloads/APP_Limonene_In_Citrus_Rinds_By_GCMS.pdf" target="_blank" rel="nofollow noopener">https://www.perkinelmer.com/PDFs/downloads/APP_Limonene_In_Citrus_Rinds_By_GCMS.pdf</a><br><br> Introduction to Gas Chromatography<br><br> <a href="https://youtu.be/ZpPzImDSfqc" target="_blank" rel="nofollow noopener">https://www.youtube.com/watch?v=ZpPzImDSfqc</a><br><br> Essential Oil GC/MS Testing with Dr. P<br><br> <a href="https://youtu.be/LtWq6jkoi9o" target="_blank" rel="nofollow noopener">https://youtu.be/LtWq6jkoi9o</a><br> Application of Comprehensive Two-Dimensional Gas Chromatography (GC6GC) to the Qualitative Analysis of Essential Oils<br><br> This paper investigates the separation of moderately complex samples by comprehensive two-dimensional gas chromatography (GC6GC).<br><br> The analysis of spearmint (Mentha spicata) and peppermint (Mentha piperita) essential oil components, including acetates, alcohols, furans, ketones, sesquiterpenes, and terpenes, was achieved by one-dimensional gas chromatography with quadrupole mass spectrometry detection (GC/MSD) and GC6GC with flame ionization detection.<br><br> Peppermint essential oil was found to contain 89 identifiable peaks by GC6GC compared to 30 peaks in the GC/MSD chromatogram.<br><br> Likewise, 68 peaks were found in the GC6GC chromatogram of spearmint (compared to 28 in GC/MSD).<br><br> Plots of the first dimension versus second dimension retention times provided a fingerprint of the two essential oils, which revealed 52 similar compounds between the two essential oils as opposed to 18 matches by 1D GC.<br><br> <a href="https://s3.amazonaws.com/academia.edu.documents/46578306/Application_of_Comprehensive_TwoDimensio20160617-6908-nar2dx.pdf?AWSAccessKeyId=AKIAIWOWYYGZ2Y53UL3A&amp;Expires=1511450647&amp;Signature=a0FdP0KQbxBjZAl1SxqbChmS2oE%3D&amp;response-content-disposition=inline%3B%20filename%3DApplication_of_comprehensive_two-dimensi.pdf" target="_blank" rel="nofollow noopener">https://s3.amazonaws.com/academia.edu.documents/46578306/Application_of_Comprehensive_TwoDimensio20160617-6908-nar2dx.pdf?AWSAccessKeyId=AKIAIWOWYYGZ2Y53UL3A&amp;Expires=1511450647&amp;Signature=a0FdP0KQbxBjZAl1SxqbChmS2oE%3D&amp;response-content-disposition=inline%3B%20filename%3DApplication_of_comprehensive_two-dimensi.pdf</a><br>
