Red cinchona

Cinchona rubra, red cinchona, is the bark of C. Succirubra or of its hybrids, containing not less than 5% of cinchona alkaloids. From it is prepared the compound tincture of cinchona.

Sweet Tincture of Ked Bark (Cinchona). Red cinchona bark, in fine powder, 4 troy ounces strong alcohol and s mip, sufficient quantity dilute alcohol (alcohol 3 parts to 1 part water), 14 fluid drachms. Moisten the cinchona with the dilute alcohol, and pack in a glass funnel, in the neck of which sufficient tow (free from tar) has been placed, to act as a filter cover the surface with a piece of perforated paper, and pour on alcohol previou y mixed with an equal volume of syrup until it has reached the tow and the surface of tho powder is covered cork the neck of the funnel and allow it to macerate 48 hours then remove the cork and continue the percolation with equal parts of alcohol and syrup, mixed, untU 16 fluid ounces have been obtained.

You may be wondering why Pasteur was mixing his tartaric acid with cinchonidine. Cinchonidine is a chiral compound that is extracted from the bark of the red cinchona tree along with quinine, and was a well known substance in the midnineteenth century. In later years, Pasteur had great interest and success in using his chemistry knowledge to cure diseases, and no...

Sometimes natural fine chemicals are by-products in bulk products refining. Examples are (a) lecithin and steroids in vegetable oil refining (b) betaine, pectin and raffinose in sugar manufacture (c) quinic acid in quinine extraction of the bark of Cinchona trees (d) chitin and the red pigment asthaxanthin in lobster and shrimp processing and (e) lanolin, lanosterol and cholesterol in sheep wool purification. 

QUIN IN.—Quinta or quina.—This important substance, which was discovered by Pelletier in 1820, is found naturally in the bark of several species of cinchona, which inhabit the Eastern slopes of the Cordillera in Bolivia, Peru, and New Granada. Three principal species ofbark occur in commerce—the yellow, true, or Calisaya bark, obtained from cinchona cordi-folia the red, yielded by c. ohlongifolia and tire pale, from c. condamima. It is found, also, though in smaller quantities, In a variety of barks, which are nearly all obtained from trees of the same family, the distinctive characteristics of which are but imperfectly known. 

Cinchona red is a reddish-brown, insipid, inodorous substance. 

Other Cinchona Alkaloids Dissolve about 2.5 g of sample in 60 mL of water contained in a separator, add 10 mL of 6 A ammonium hydroxide, extract the mixture successively with 30 mL and 20 mL of chloroform, and evaporate the combined chloroform extracts to dryness on a steam bath. Dissolve 1.5 g of the residue in 25 mL of alcohol dilute the solution with 50 mL of hot water add 1 A sulfuric acid (about 5 mL) until the solution is acid, using 2 drops of methyl red TS as the indicator and neutralize the excess acid with 1 A sodium hydroxide. Evaporate the solution to dryness on a steam bath,... 

A distorted octahedral, deep red complex of 1,2-diamine (R,R )-trans-l,2-bis(N-pyrrolidino)cyclohexane (L), L-0s04 has been made at low temperatures.103 It is very reactive and is formally a 20e outer valence shell species. The isolation of this and relevant 1,2-diamine complexes throws light upon the mechanism of enantiose-lective dihydroxylation of alkenes noted below. The tetroxide has important commercial use in the stoichiometric and catalytic cis-hydroxylation of alkenes. There has been much discussion of the mechanism, particularly for the enantiospecificity achieved in the presence of cinchona alkaloids or other chiral agents.104...
