Astaxanthin and its hydroxylated derivatives were purified from the carotenoids extract of N-5 using an open chromatography column of silica gel 60 coupled with a mobile phase of hexane−acetone (7:3‚ v/v). Using HPLC method C‚ a first fraction (1) was eluted at 16.66 min and gave a [M+ + 1] ion peak at m/z 629‚ corresponding to 2‚2′-dihydroxyastaxanthin. A second fraction

Abstact 1) Introduction An adulterant is a chemical substance which should not be contained within other substances‚ such as food‚ beverages‚ fuels‚ for legal or other reasons. The addition of adulterants is called adulteration. The word is appropriate only when the additions are unwanted by the recipient. Otherwise the expression would be food additive. Adulterants when used in illicit drugs are called cutting agents‚ while deliberate addition of toxic adulterants to food or other products

January 27‚ 2014 Introduction This laboratory has its first objective to familiarize with the thin layer chromatography (TLC) technique. Second‚ each student has to identify the unknown components by comparing it to one of the tree dissolved liquid analgesics: Acetaminophen‚ Aspirin and Caffeine. Finally‚ calculating the Rf value by measuring the mobile and stationary phase. Chromatography is a technique used to separate mixtures into their compounds. It’s based on a mobile phase and a stationary

Chemical composition of the essential oil of Majorana hortensis grown in Uttaranchal Shishir Kumar Singh Abstract GLC and GC-MS Analysis was done to analyse the hydrodistilled essential oil of Majorana hortensis grown in Uttranchal state of India. The 36 compounds could be identified out of 50 by their mass spectra accounting for 93% of the oil. The major ones are trans-sabinene hydrate (41.2%)‚ terpinen-4-ol (18.5%)‚ cis-sabinene hydrate (9.3%)‚ a-terpineol (3.8%)

specific and accurate reverse phase high performance liquid chromatographic method was developed for the simultaneous determination of chlorpheniramine maleate and phenylephrine in tablet dosage forms. A reversed-phase C-18 column (250 mm × 8 mm i.d.‚ particle size 10 µm) column with mobile phase consisting of acetonitrile and phosphate buffer 55:45 (v/v) (pH 5.6 ± 0.02‚ adjusted with triethylamine) was used. The flow rate was 1.0 ml/ min and effluents were monitored at 255 nm. The retention times

Proteins (ACTIVITY 8) Gallemit‚ Lacei Machelle• • January 17‚ 2013 ABSTRACT Chromatography is one of the most useful methods of separating minute amounts of complex mixtures into the pure substances contained therein. Chromatographic separations are effected by allowing the components in the mixture to be distributed in two phases‚ one being stationary‚ and the other‚ mobile. Partition chromatography involves two main distribution systems‚ one system is composed of a gas and a liquid and

Identification of Plant Pigments by Paper Chromatography Biology 1107L Introduction All living organisms require energy for their chemical processes. The ultimate source of this energy is the sun. Plants convert light energy into the chemical energy of sugars. During photosynthesis pigments are used to capture light energy. Pigments of green plants can easily be separated and identified using a technique called paper chromatography. The purpose of this experiment is to separate
