Softer Foods, Smaller Portions. While following a bland food diet, a patient eats softer foods such as cream of wheat, mashed potatoes or cooked rice in place of heavier starches such as bread, crackers and grain cereals.
Quinine is an alkaloid, a naturally occurring chemical compound. How it works as a medicine is not entirely clear. Quinine was first isolated in 1820 from the bark of a cinchona tree. Bark extracts have been used to treat malaria since at least 1632.
Quinine is a strongly fluorescent compound in dilute acid solution with two excitation. wavelengths (250 and 350 nm) and a fluorescence emission at 450 nm. The factors which affect. the quantitative determination of quinine (such as concentration quenching and chemical. quenching) will be studied as well as the interpretation of the emission spectra. Chemicals: - Quinine stock solution: (100.0 Âµg/mL), 120.7 mg quinine sulfate dihydrate or 100.0 mg.
