IV: Analytical applications I: What can be analyzed? At present, Supercritical Fluid Chromatography is very useful in this industries. And it has been used in the many fields. Pharmaceutical: It’s used in the drug industries to process the compound relate to the health and life as a vitamins, steroids, antibiotics, barbiturates, taxol, prostaglandins, non-steroidal anti-inflammatory agents, or etc. Moreover, it has been used for the achiral separations and purifications of substance in…

The main concern regarding the use of electronic cigarettes is that no one knows what ingredients or chemicals are in them. It's difficult to decide if they are safer than cigarettes if one doesn't have enough information to compare the two. Although there have not been enough studies conducted to know exactly how many chemicals are in electronic cigarettes, there have been 42 identified (Harmful Chemicals in Electronic Cigarettes). Out of the 42 identified chemicals, there are certain ones…

In conclusion, we reported the synthesis of fused and isolated triazoles based on thieno[2,3-d]pyrimidines. The synthesized 1,2,4-triazolo compounds were screened for their anticancer activity at a concentration of 10 μΜ against a panel of 60 cell lines derived from nine different types of cancers, and also screened for their PDE 5 inhibitory activity. The possibility of combining 1,2,4-triazolo moiety to thieno[2,3-d]pyrimidines should open new opportunities for the rational design of…

weight 58,079, isthe simplest and the most important of the ketones. It is a colourless, mobile, flammableliquid with a mildly pungent and somewhat aromatic odour. It is miscible in all proportionswith water and with organic solvents such as ether, methanol, ethyl alcohol, and esters.Acetone is used as a solvent for cellulose acetate and nitrocellulose, as a carrier for acetyleneand as a raw material for the chemical synthesis of a wide range of products such as ketene,methyl methacrylate,…

the fruits of V. macrocarpon, V. myrtillus and V. uliginosum (Table, figure, pp). 6.3.3. Powder behaviour of V. macrocarpon, V. myrtillus and V. uliginosum with different chemical reagents Powder behaviour is also an important tool for the determination of constituents in herbal drugs and it provides an idea about their chemical nature. The different colour changes observed in long, short UV and visible light after treatment of fruit powder of V. macrocarpon, V. myrtillus and V.…

vaccine. They used monkey tissue in the cultures in order to have the virus grown in the lab for research. Salk then killed the polio virus, in those cultures, with a certain amount of formaldehyde, a colorless and odorless toxic gas derived from methanol and oxidation, (Salk Develops A Polio Vaccine). Salk did not trust his vaccine completely, so early in 1952 he used it on children that already had Polio. Their bodies produced the Polio virus antibodies which led Salk to believe in his vaccine…

Lots of American farmers found themselves unable to make enough money to support their families. One of the main ingredients of Moonshine is corn. A farmer could take a subpar corn farm and turn it into a goldmine. Obviously the Government did not approve of this practice. There are a couple good reasons for the Government to oppose this practice. With underground Moonshine sales growing they were losing a large amount of tax revenue; secondly, there was no way to regulate production, and…

Above mentioned cultures are uniformly spread on to the plates containing the media using cotton swabs. 100 mg of Tal Sindoor is dissolved in 1ml of methanol and 2ml of water. Sterile discs soaked in the suspension of Tal Sindoor for 10 minutes and dried are placed on the previously swabbed petri plates. Later the plates have to be incubated at 37oC for 24 hours. After 24 hours of incubation the plates…

HPLC method was developed and validated for determination of content of Ketorolac Tromethamine and Phenylephrine Hydrochloride in immediate release tablet. UV spectrophotometric method was developed and validated to study drug release profile of Ketorolac Tromethamine and Phenylephrine Hydrochloride in immediate release tablet. Background:…

1.5 REVIEW OF LITERATURE 1.5.1 Phytoconstituents of Enicostemma littorale Blume and its medicinal properties Enicostemma littorale Blume contains secondary metabolites such as alkaloids, catechins, saponins, sterols, triterpinoids, phenolic acid flavonoids and xanthones. Thse secondary metabolites exhibit various biomedical properties like anti-inflammatory [29] and anticancer [30] properties. Aqueous extract of E. littorale in alloxan induced diabetic rats was also reported to possess…
