Caffeine Caffeine is a bitter, white crystalline xanthine alkaloid that is a psychoactive stimulant drug. Caffeine was discovered by a German chemist, Friedrich Ferdinand Runge, in 1819. He coined the term “kaffein”, a chemical compound in coffee, which in English became caffeine.

Isolation of Caffeine from Tea Leaves Isolation of Caffeine from Tea Leaves. Caffeine is an alkaloid stimulant with a cyclic backbone structure analogous to the purine structures of DNA, giving it the ability to affect biochemical pathways in the body1. In commercial application, caffeine supplements pharmaceuticals and certain beverages such as coffee or tea. Standard tea bags contain 2.00 +/- 0.05 g of tea leaves along with approximately 55 mg of caffeine[1]. Using the proper extraction methods, the caffeine within a tea bag could potentially be isolated to yield a pure solid; the mass of this solid would reflect the actual yield of caffeine in the tea.

Structural formula The structural formula of a chemical compound is a graphic representation of the molecular structure, showing how the atoms are arranged. The chemical bonding within the molecule is also shown, either explicitly or implicitly. Unlike chemical formulas, which have a limited number of symbols and are capable of only limited descriptive power, structural formulas provide a complete geometric representation of the molecular structure.

Is caffeine, or it's metabolite paraxanthine responsible for the stimulation experienced in caffeinated beverages? When caffeine goes into our bodies, some of it is modified into paraxanthine. Some say most of the consumed caffeine (~ 80%, as stated by this paper: http://www.ncbi.nlm.nih.gov/m/pu...) is converted. After that process, both caffeine and paraxanthine act as competitive inhibitors against adenosine.

- OPSS Answer. The difference has to do with the amount of water associated with the caffeine molecule. The term caffeine can refer to any form of caffeine, regardless of its water content. “Caffeine anhydrous has essentially no water—just 0.5%. For this reason, logic and chemistry suggest that anhydrous caffeine is more potent.

- Caffeine is a xanthine which acts in the body’s cells by different mechanisms of action and on a wide range of molecular targets. It intervenes as an antagonist of the adenosine receptors, inhibitor of phosphodiesterase enzymes, sensitizer of calcium liberation channels, and GABA receptor antagonist [26].

Caffeine Myths and Facts Caffeine is a stimulant to the central nervous system, and regular use of caffeine does cause mild physical dependence. But caffeine doesn't threaten your physical, social, or economic health the way addictive drugs do. (Although after seeing your monthly spending at the coffee shop, you might disagree!).affeine content can range from as much as 160 milligrams in some energy drinks to as little as 4 milligrams in a 1-ounce serving of chocolate-flavored syrup. Even decaffeinated coffee isn't completely free of caffeine. Caffeine is also present in some over-the-counter pain relievers, cold medications, and diet pills.

- Shanbhag Caffeine Extraction 2006 After the extraction procedure, the organic solution of dichloromethane and caffeine is dried with an anhydrous inorganic salt. Crude caffeine is recovered as a solid residue by evaporation of the dichloromethane. The solubility of caffeine in water at 20°C is 2.2 g per 100 mL, so there is no problem in keeping it in water solution while you filter off the spent tea leaves and calcium salts. Caffeine is far more soluble in dichloromethane: 10.2 g per 100 mL at
