Inosit is found in the muscles, liver, spleen, kidneys, super-renal cavity, lungs, brain, testicles, and in the urine in pathological cases. It is found very widely distributed in the vegetable kingdom, especially in unripe fruits, in green beans, (phaseolus vulgaris), and therefore it is also called Phaseomannit. Inosit crystallizes in large, colorless, rhombical crystals of the monoclinic system, or, if not pure and if only a small quantity crystallizes, it forms groups of fine crystals similar to cauliflower. It looses its water of crystallization at 110 C. , also if exposed to the air for a long time. Such exposed crystals are non-transparent and milk-white. The crystals melt at 217 C. Inosit dissolves in six parts of water at ordinary temperature, and the solution has a sweetish taste. It is insoluble in strong alcohol and in ether. Inosit does not ferment with beer-yeast; it dissolves copper oxyhydrate in alkaline solutions, but does not reduce on boiling. It gives negative results with Moores or Bottger-almeus bismuth tests. If inosit is evaporated to dryness on a platinum foil with nitric acid and the residue treated with ammonia and a drop of calciumchloride solution and carefully re-evaporated to dryness, a beautiful rose-red residue is obtained (scherers inosit test). If we evaporate an inosit solution to incipient dryness and moisten the residue with a little mercuric-nitrate solution, we obtain a yellowish residue on drying, which becomes a beautiful red on strongly heating. The coloration disappears on cooling, but it reappears on gently warming (g-alloiss inosit test). To prepare inosit from a liquid or from a watery extract of a tissue, the albumin is first removed by coagulating at boiling heat. The filtrate. . . This item ships from La Vergne,TN.<
