Even though Ayurveda has gained popularity among the medicinal systems there is a hindrance to its further development. One of the burning problems is the practice of adulteration which creates doubts and disbelief in the curative capability of traditional systems.In the present work methods & reasons for adulteration are described. The efficacies of Ayurvedic Products are critically dependent on an uninterrupted availability of herbs. The unethical practice of adulteration by the drug manufacturers would not only reduce the efficacy of the drugs but also affect the trust of the people in the traditional healthcare systems. Adulteration may be evaluated by different methods like morphological or organoleptic tests, microscopic evaluation, chemical evaluation, physical evaluation, chromatography, spectrophotometry etc. The solution lies in ensuring the availability of crude drugs. Studies on adulteration practices will have to be taken up along with identification of the scares drugs. ...

AU - Tsafaras, Ilias. AU - Petrakis, Eleftherios A.. AU - Mousdis, George A.. PY - 2014/4/1. Y1 - 2014/4/1. N2 - Quantitative analysis of food adulterants is an important health and economic issue that needs to be fast and simple. Spectroscopy has significantly reduced analysis time. However, still needed are preparations of analyte calibration samples matrix matched to prediction samples which can be laborious and costly. Reported in this paper is the application of a newly developed pure component Tikhonov regularization (PCTR) process that does not require laboratory prepared or reference analysis methods, and hence, is a greener calibration method. The PCTR method requires an analyte pure component spectrum and non-analyte spectra. As a food analysis example, synchronous fluorescence spectra of ...

Fig. 1 shows the results of measuring a Class 2 residual solvents standard solution (water-soluble articles) using a 30 m column with an internal diameter of 0.53 mm, compared to the results obtained from separate measurements by GC-FID. With a 30 m L. x 0.53 mm I.D. column, the column outlet pressure will be negative, so the flow rate prescribed in Procedure A cannot be set. Here, the linear velocity of 35 cm/s prescribed in Procedure A was achieved by connecting an 82 mm L. x 0.18 mm I.D. flow restrictor to the column outlet, and a chromatogram pattern approximating the GC-FID results was obtained. The column flow rate with GC-MS was calculated at 4.86 mL/min, but measurements were not a problem for the GCMS-QP2020/QP2010 Ultra because of their high vacuum performance.. ...
Tainted heparin that has killed 81 people in the U.S. may have been intentionally contaminated, witnesses appearing before a congressional committee said yesterday.  In written testimony, a Food & Drug Administration (FDA) official told lawmakers that it does strain one’s credulity to think that the heparin contamination was accidental. The head of Baxter International, the company that issued a massive recall of heparin earlier this year, said that he was also of the belief that the heparin contamination was deliberate.. In March, the FDA confirmed that it had found a counterfeit ingredient, oversulfated chondroitin sulfate, in samples of the active ingredient used in Baxter heparin. The chemical had been molecularly changed to mimic heparins blood thinning properties. That ingredient was supplied to Baxter by Changzhou SPL, a Chinese plant partially owned by Wisconsin-based Scientific Protein Laboratories. Since then, ...
WASHINGTON -- Contamination with oversulfated chondroitin sulfate -- the same contaminant responsible for a worldwide heparin recall in 2008 -- has prompted a new recall by B. Braun Medical.
HealthDay Reporter. WEDNESDAY, Dec. 3 (HealthDay News) -- A final report on the deadly contamination of the blood thinner heparin confirms that the problem was caused by a man-made chemical that was added to batches of the drug imported from China, U.S. investigators report.. The crisis, which began last November, resulted in 152 adverse reactions and as many as 81 deaths in the United States. The Chinese heparin, contaminated with the chemical oversulfated chondroitin sulfate, was found in at least 10 countries, according to federal officials.. The last case was reported on January 31, said Dr. Priti R. Patel, a medical epidemiologist with the U.S. Centers for Disease Control and Prevention, and a member of the investigation team that wrote the report.. Published in the Dec. 4 issue of the New England Journal of Medicine, the report describes the adverse reactions caused by the contaminant and links it to a specific substance, Patel said. The reactions included a drastic drop in blood ...
At Anant, we make and supply a variety of impurities and reference materials for use in quality control and development. Impurities derive from different sources as shown by the schematic below. Impurities that ultimately find their way in the final API originate from a number of sources. Impurities in raw materials and key intermediates are called KSM impurities. Impurities are generated during the various stages of a process come from degradation of stage reactants or products, side reactions at one or multiple stages, residual solvent(s)/reagents, etc. Impurity formation is fuelled by non-ideal reaction or workup conditions and are a function of the reaction environment. Degradation of material (either intermediates or final product) is an additional source of impurities and is controlled by careful handling and storage.. ...
We present a numerical study of collisional transport in a tokamak pedestal in the presence of non-trace impurities, using the radially global delta-f neoclassical solver PERFECT [M. Landreman et al. 2014 Plasma Phys. Control. Fusion 56 045005]. It is known that in a tokamak core with non-trace impurities present the radial impurity flux opposes the bulk ion flux to provide an ambipolar particle transport, with the electron transport being negligibly small. However, in a sharp density pedestal with sub-sonic ion flows the electron transport can be comparable to the ion and impurity flows. Furthermore, the neoclassical particle transport is not intrinsically ambipolar, and the non-ambipolarity of the fluxes extends outside the pedestal region by the radial coupling of the perturbations. The neoclassical momentum transport, which is finite in the presence of ion orbit-width scale profile variations, is significantly enhanced when impurities are present in non-trace quantities, even if the total parallel

For the first time, a comprehensive investigation of the impurity profile of the synthetic thyroid API (active pharmaceutical ingredient) liothyronine sodium (LT3Na) was performed by using reversed phase HPLC and advanced structural elucidation techniques including high resolution tandem mass spectrometry (HRMS/MS) and on-line hydrogen-deuterium (H/D) exchange. Overall, 39 compounds were characterized and 25 of these related substances were previously unknown to literature. The impurity classification system recently developed for the closely related API levothyroxine sodium (LT4Na) could be applied to the newly characterized liothyronine sodium impurities resulting in a wholistic thyroid API impurity classification system ...

In 1820 a little book was published in Britain and the USA that shocked its readers and arguably began the process that led to modern food law in Europe and North America. A Treatise on Adulterations of Food, and Culinary Poisons was penned by a German-born chemist called Frederick Accum, who lived and worked in London. Accums book was the first to alert consumers to what was really in the food they ate and how unscrupulous traders were routinely swindling them. His observations were taken seriously because they were based on scientific analysis. Accum believed that the science of chemistry was the best way to detect and combat food adulteration. But it took 40 years until the 1860 Food Adulteration Act started a legal crackdown on the practice and a further 15 before the 1875 Sale of Food and Drugs Act established adulteration offences and set up the network of analysts and inspectors needed to enforce the new law. Food adulteration has a very long history, and last years horsemeat in beef ...

The minimum purity of a gas refers to the specified impurities that characterize the pure gas. The specific limits for the impurities are not exceeded. In the case of gases without details on impurities, the specification of their purity is to be seen as a typical value. In the case of a number of high purity gases, every filled cylinder is accompanied by a certificate of analysis confirming that the maximum limits for impurities have not been exceeded. This is noted for the gas purities to which it applies. It does not apply to Gases in Small Containers.
