بررسی مقایسه ای ژرم پلاسم بابونه ایران با استفاده از مارکر gc, rapd و gc-ms

بررسی تنوع ژنتیکی و فیتوشیمیایی ژرم پلاسم کلپوره استان کرمان با استفاده از نشانگر مولکولی RAPD و روش GC/MS

کلپوره (Teucrium polium L.) گیاهیست علفی، پایا و پرشاخه که در نواحی مختلف اروپا و خاورمیانه ازجمله ایران به‌صورت وحشی می‌روید. برای بررسی تنوع ژنتیکی ژرم‌پلاسم این گیاه در استان کرمان، ابتدا با استفاده از روش CTAB استخراج DNA از 15 نمونه جمع‌آوری شده انجام شد. از 15 آغازگر RAPD برای انجام PCR استفاده شد. داده‌های بدست آمده حاصل از الکتروفورز توسط نرم‌افزار NTSYS با ضریب تشابه دایس و به‌روش UPGM...

Chemical Analysis of Pesticides Using GC/MS, GC/MS/MS, and LC/MS/MS

There are well over 500 registered pesticides worldwide for use in agricultural regions and new agrochemicals are introduced to the marketplace continuously. This chapter deals with the chemical analysis methods for the main pesticide chemical classes that are most frequently analyzed with gas chromatography (GC) or liquid chromatography (LC) coupled to mass spectrometry (MS). GC amenable pesti...

Polymer Analysis Using Pyrolysis-GC-FTIR-MS and GC-AED

Fluxome analysis using GC-MS

Fluxome analysis aims at the quantitative analysis of in vivo carbon fluxes in metabolic networks, i. e. intracellular activities of enzymes and pathways. It allows investigating the effects of genetic or environmental modifications and thus precisely provides a global perspective on the integrated genetic and metabolic regulation within the intact metabolic network. The experimental and comput...

Photo-ionization Gc×gc-hrtof/ms for Aviation Fuel Characterization

Recent application of photo-ionization (PI) coupled with GC×GC-HRTOF/MS for authentic standard mix called century mix along with several groups of petrochemical samples demonstrated PI as an effective soft-ionization technique to characterize volatile mixtures particularly, hydrocarbons [1]. This soft-ionization technology was shown to enhance analyte speciation by providing both molecular ions...

GC - MS analysis of Polygala

The present study presents the bioactive profile of Polygala arillata Buch.-Ham ex D.Don using GC-MS. The phytochemical constituents of leaf and stem ethanolic extracts of Polygala arillata were investigated using Fisons Gas-chromatography – Mass spectrometry. The mass spectra of the compounds in the leaf and stem extracts was matched with National Institute of standards and Technology (NIST) L...
