The determination region of solubility of methanol with gasoline of high aromatic content was investigated experimentally at temperature of 288.2 K. A type 1 liquid-liquid phase diagram was obtained for this ternary system. These results were correlated simultaneously by the UNIQUAC model. The values of the interaction parameters between each pair of components in the system were obtained f...

There is considerable interest in the discovery of hypocholesterolemic drugs whose mode of action is the inhibition of sterol biosynthesis. Culture broths of microorganisms have yielded active compounds that specifically inhibit 3hydroxy-3-methylglutaryl coenzyme A (HMGCoA) reductase, the rate-limiting enzyme in cholesterol biosynthesis. The first of these to be described was ML-236B (compactin...

Sir: Clinical and nutritional studies have indicated that high cholesterol levels in the blood may be one of the major causes of atherosclerosis and coronary heart disease. In this context the metabolism of cholesterol in liver is of paramount importance because liver seems to be the sole organ supplying serum cholesterol and because the conversion of cholesterol into bile acids in liver is qua...

The flavonoids of Crotalaria grahamiana (family Popilionaceae) were isolated from the alcoholic extract by partition with benzene, diethyl ether, ethyl acetate respectively. On the basis of chemical and spectral analysis their structures are elucidated as 4’hydroxy flavone-7-O-rhamnoside and its aglycone.Identification of unknown compounds were established through comparison of chromatographic ...

Jude K. Coompson, B.S. Marquette University, 2014 Benzene is a constituent component of crude oil that has been classified as a carcinogen by the EPA with a maximum contamination level (MCL) of 5ppb in drinking water. However, of the aromatic compounds, benzene has one of the lowest polymer-water partition coefficients using commercially available polymers as sensor coatings, resulting in poor ...
