MASS SPECTROMETRY(mass-spec) -2013 - P.ravisankar- WHAT ABOUT MASS SPECTROMET... Quantitative Analysis of 30 Drugs in Whole Blood by SPE and UHPLC-TOF-MS, No public clipboards found for this slide.  It is a research technique that exploits the magnetic properties of certain atomic nuclei. The types of spectroscopy depends therefore on the interaction matter has with radiation: The table below gives a list of commonly used spectroscopic techniques used, the type of electromagnetic radiation involved, the type of interaction between the electromagnetic radiation and the matter, as well as the type of matter which can be observed. Digestion of Dietary Proteins in the Gastro-Intestinal Tract (GI tract) Thus it is the study of how each of the above electromagnetic radiations interacts with molecules, compounds, atoms or even the nucleus. It is a well known fact that light is composed of electromagnetic radiation which is often treated as a wave phenomenon which has a defined wavelength. To remember the order of the electromagnetic spectrum take a look at the image below along with the text which follows: The electromagnetic spectrum. 4. Metabolomics is defined as “systematic study of the unique chemical fingerprints that specific cellular processes leave behind” [].Metabolom includes the final metabolites of a cell, or biological organisms [].Herbal metabolomics is unbiased, high-performance and specific analysis of … The foaming ability of saponins is caused by the combination of a hydrophobic (fat-soluble) sapogenin and a hydrophilic (water-soluble) sugar part. Far Infrared (Far IR) – between 10,000 nm (or 10 μm) to 1000 μm (or 1mm). Introduction to spectroscopy. Saponins are glucosides with foaming characteristics. Students of D.pharm can also use these questions for thier university or any competitive exams. 3] Radio Spectrum – Finally to the extreme right of the electromagnetic spectrum, i.e. Modern methods of extraction, application of latest techniques like Spectroscopy, chromatography and electrophoresis in the isolation, purification and identification of crude drugs. M. Pharm (Pharmacognosy) (First Semester) PHAR-511 Modern Analytical Techniques Unit - 1 UV-Visible Spectroscopy: Principle of UV-Visible Spectroscopy, Chromophores and their interaction with UV-visible radiation and their utilization in structural, qualitative and quantitative analysis of … ), • Coupled chromatographic - spectroscopic techniques and their applications NMR spectroscopy is a primary method of measurement and it can be also used to evaluate the quality of drugs and excipients besides the possibility to identify a drug by the comparison of the H or C NMR spectra of the substance to be examined and a reference substance. Raman spectroscopy is becoming one of the most popular analytical measurement tools for pharmaceutical applications ranging from verification of raw materials to process monitoring of drug production to quality control of products. (Picture taken from http://www2.chemistry.msu.edu/faculty/reusch/VirtTxtJml/Spectrpy/UV-Vis/spectrum.htm on August 24, 2011).  It determines the physical and chemical properties of atoms or the molecules in which they are contained. The wavelength of light is what determines the photo energy possessed by the light which can be calculated by the equation. On the vertical axis is the relative abundance of each ion detected. The Near infrared Region : This is also known as vibration region and ranges from 2.5 to 25 mu.

This course is dedicated to the study of basics of the quantitative NMR spectroscopy method. Fundamentals of Analytical Chemistry 8th Ed., by Douglas A. Skoog, Donald M. West, F. James Holler, Stanley R. Crouch. Infra-red spectroscopy III. The FTIR spectroscopic studies revealed different Pharmacognosy: Fundamentals, Applications and Strategies explores a basic understanding of the anatomy and physiology of plants and animals, their constituents and metabolites. INTRODUCTION • Spectroscopy is the branch of science dealing with the study of interaction of electromagnetic radiation with matter. Spectroscopy is the study of interaction between matter (i.e. The aglycone part, which is also called sapogenin, is either steroid (C27) or a triterpene (C30). The basis of photo-thermal spectroscopy is the change in thermal state of the sample resulting from the absorption of radiation. It is a field of study within Chemistry focused on natural products isolated from different sources and their biological activities. Introduction. the microwaves and radio frequency, it is common use frequency as a measure of type of electromagnetic radiation instead of wavelength. This is because large number of absorption bands is observed in the IR spectra of organic molecules and the probability that any two compounds will produce identical spectra is almost zero. Application of Chromatography in in the isolation, purification and identification of crude drugs. ... 1.1 General Introduction to Pharmacognosy and its importance in herbal drug industry. Pharmacognosy Journal. Clipping is a handy way to collect important slides you want to go back to later. Pharmacognosy I (Lab Work) ... • Methods of identification of isolated compounds (infrared spectroscopy, visible-ultraviolet spectroscopy, nuclear magnetic resonance spectroscopy, mass spectroscopy, etc. Ultraviolet-Visible (UV-Vis) Spectroscopy – Woodward-Fieser Rules to Calculate Wavelength of Maximum Absorption (Lambda-max) of Conjugated Dienes and Polyenes ... Pharmacognosy and Benefits of Nutmeg and Mace. NMR spectroscopy provides a fingerprint spectrum characteristic of the saccharide that is sensitive to the small structural differences, such as changes in a single inter-sugar linkage. The branch is focusing on natural products research, traditional medicine, ethnobotany and phytochemistry from plant, marine and other life origins on both analytical and preparative scale. These radiations do not have any lower limit of wavelength, but their upper limit lies at 0.01 nm. Pharmacognosy Journal (Phcog J.) 2018;10(4):753-757. Looks like you’ve clipped this slide to already. Apr 27, 2020 - In this video we have discussed some important mcqs on Infrared Spectroscopy in pharmacognosy.
