Background: Derived form the greek words for colour (Chroma) and writing (graphe). Chromatography is a method is method in which different kinds of the coloured chemical mixtures are separated. In the early 1900s, Mikhail Tswett, a Russian botanist, was interested in the individual compounds presented in plants. He understood that removing ground up plants extracts with the dissimilar solvents will provide assorted coloured solutions. Tswett conducted an experiment which involved pouring a plant
traditional column chromatography because of the forcibly pumped mobile phase. Recently, ultrafast analysis using a high-pressure-resistant apparatus has been attracting attention. UHPLC (Ultra High Performance LC) is becoming established as an abbreviation for this ultrafast LC method. In 1941 Martin and Synge, described the discovery of liquid-liquid partition chromatography and also laid the foundation of Gas liquid chromatography and High performance liquid chromatography. They also introduced

Chromatography Different types of Chromatography Paper chromatography Paper chromatography is a method of testing the purity of compounds and helps identify the substances within it. Using the paper chromatography is a useful and simple technique as it is relatively quick and requires small quantities of material. Paper chromatography separates colours, this also happens in the thin layer chromatography. Using the paper chromatography method, substances the distribution between stationary phase and
Electrospray is the technique that is used by analytical chemist for the creation of ions from a sample. The technique uses electricity to form an exceptionally fine liquid aerosol. Other techniques that were used before electrospray used gas to form these aerosols for analyses. Electrospray is particularly useful over using gas because it is a soft ionization technique. Soft ionization techniques ionize the sample with minor fragmentation of the molecule, giving an observable molecular ion for the
Chromatographic Analysis of a Commercial Analgesic’s Active Component seeks to separate, identify, quantify and analyze the active component found in Biogesic®, which may be useful for public awareness despite its wide acceptance and availability in the market. Furthermore, this study applies thin layer chromatography (TLC) technique since it is the simplest, cheapest yet most effective approach in terms to the study’s objectives. The TLC method implies Rf (Rate of flow) values where it is given by the
CHEM 333L Organic Chemistry Laboratory Revision 1.1 Isolation of Lycopene from Tomato Paste using Column Chromatography In this laboratory exercise we will isolate the pigment Lycopene from tomato paste. In a follow up lab, we will examine the UV-VIS spectrum of Lycopene, isomerize it and then examine the isomer’s spectrum for comparison. Lycopene, the red pigment of the tomato, is a C40-carotenoid made up of eight Isoprene units; making it a tetraterpene. Other sources of the compound
current manufacturing processes are either difficult to scale up, high in cost, or have the potential to affect the structure-activity properties of these peptides. To overcome these challenges, we have proposed in this review, the use of 'omic ' techniques and high throughput simulation models to forecast the

medicinal plants with hypoglycemic effect in diabetes management. The effects of these plants can delay the progression of diabetic complications and correct the metabolic abnormalities. Recently, a number of medicinal plants have been reported to be useful in diabetes around the world and has been used empirically as antidiabetic and anti-hyperlipidemic drugs. Despite the presence of known antidiabetic drugs in the pharmaceutical market, diabetes and related complications continue to be a major medical
