A Simple, Rapid Method for Circular Paper Chromatography

A Simple, Rapid Method for Paper Chromatography of Barbiturates.

Barbiturates are extracted quantitatively into ethyl ether from biologic fluids buffered to pH 6. A measured portion of the ether extract is then impinged to dryness and the residue spotted on Whatman No. 2 paper that has been previously dipped in alkali and dried. The paper is developed by descending chromatography with chloroform saturated with water. The barbiturate may then be located and a...

A Simple and Rapid Leaf Genomic DNA Extraction Method for Polymerase Chain Reaction Analysis

In plants, secondary metabolites and polysaccharides interfere with genomic isolation procedures and downstream reactions such as restriction enzyme analysis and gene amplification. The removal of such contaminants needs complicated and time-consuming protocols. In this study, a simple, rapid and efficient method for leaf DNA extraction was optimized. This method use small amount of plant mater...

A Simple Electrochemical Method for the Rapid Estimation of Antioxidant Potentials of Some Selected Medicinal Plants

     Clinical and Epidemiological studies have shown that a diet rich in fruits and vegetables is associated with a decreased risk of cardiovascular diseases, cancers and other related disorders. These beneficial health effects have been attributed in part to the presence of antioxidants in dietary plants. Therefore screening for antioxidant properties of plant extracts has been one of the inte...
