Malaria description

Description of Method. Quinine is an alkaloid used in treating malaria (it also is found in tonic water). It is a strongly fluorescent compound in dilute solutions of H2SO4 (f = 0.55). The excitation spectrum of quinine shows two absorption bands at 250 nm and 350 nm, and the emission spectrum shows a single emission band at 450 nm. Quinine is rapidly excreted from the body in urine and is easily determined by fluorescence following its extraction from the urine sample. 

Description.—For the delineation of the different varieties of gamboge, the Editor has to resort to the Malaria Medka of Dr. Pereira as the best source of information on the subject . That eminent authority says —Two kinds of gamboge are described by pharmacological writers—the Siam and the Ceylon, Of these the first otfly is known in commerce.
