Example text

The sugar cane is extensively cultivated in Africa, East and West Indies (especially Cuba), Brazil, and Southern United States, particularly Louisiana. The sugar beet is extensively cultivated in France and Spain, and has been introduced with varying success into some parts of the United States. Cane-sugar is also a constituent of the sugar maple; of the carrot and turnip, of cassia pulp, etc. The sugar in fresh fruit is mainly cane-sugar; by the action of the fruit acids, or a ferment, it is generally inverted, becomes uncrys-talline, and influences polarized light in the opposite direction from that of cane-sugar, twisting the ray from right to left.

It occurs in white, hard crystalline masses or as a white powder feeling gritty to the tongue, odorless, permanent in air. Like cane-sugar it forms compounds with metallic oxides, and reduces alkaline copper solutions. Practically insoluble in alcohol, ether, or chloroform. It is not effected directly by ferments. When heated with mineral acids it forms dextrose and galactose. —When injected into the blood-vessels it appears unaltered in the urine. When taken in the alimentary canal it is perfectly assimilated.

A concentrated decoction of the drug is deprived of gum by precipitating with alcohol. The liquid is then treated with lead subacetate. The lead is removed by H 2S. The resulting liquid, after neutralization, is shaken with chloroform, which leaves on evaporation a thin, yellow, aromatic liquid, acorin. This splits into oil and sugar by hydration; by oxidation the resin and acoretin are obtained. —Tonic and carminative, and a feeble aromatic stimulant. Dose: 15 to 60 gr. ). 53. —SKUNK CABBAGE.
