The results from this experiment show that caffeine can be extracted from a tea bag due to solubility properties of the natural substances found in tea. The two major substances that the caffeine was separated from are cellulose and tannins. Due to the insolubility of cellulose in water, it was easily extracted. Tannins are soluble in water but were neutralized with sodium carbonate to produce water-soluble salts. Caffeine is soluble in methylene chloride which allowed separation of tannins from caffeine because water-soluble salts are insoluble in methylene chloride. The experimental melting point observed in the results above show that caffeine was not completely separated from methylene chloride, tannins, or cellulose. The melting point

    Planaria Caffeine Experiment

    Introduction Planaria are a type of flatworms that possess a mammalian nervous system and the ability to regenerate skin cells. The flatworms are used in a variety of experiments, which include chemical responses and experiments upon the regeneration process. When combined with addictive drugs and chemicals, such as cocaine and ethanol, the planaria display paroxysms, motor effects, and c shaped movements (Tallarida et al 2014). The planaria demonstrate their applicability of their systems in multi-drug interactions, and they display visible results in different drug combinations. (Tallarida et all 20014).…

    Pharmacology- Practical based exercise Introduction/ aims Acetylcholine (ACH) is a neurotransmitter which operate in the brain, ACH are known as cholinergic because they are released from both the parasympathetic and sympathetic systems, (Colovic, 2013). There are drugs which look to copy these effects or inhibit them, they are known as cholinergic drugs. ACH has two types of receptors, nicotinic and muscarinic receptors. Nicotine acts as antagonists for nicotinic receptors, by blocking these receptors this causes the muscles to relax.…

    Frog Caffeine Experiment

    Caffeine, one of the most commonly used psychoactive drugs, is a central nervous system stimulant that induces the sense of alertness and awareness. Inspired by the previous research on how the caffeine affects the cardiovascular system, we wanted to test the effect of different concentrations of caffeine on the heart. We used ECG stimulator on LabScribe 2 software to monitor the heart rate. We used frogs as a test subject, since both frogs and humans have a closed cardiovascular system, therefore the effect on the frog’s heart would parallel the situation of a human heart. We quantitatively measured the heart rate and found out that caffeine significantly increases the heart rate of the Rana sphenocephala Introduction:…

    Activated Carbon: Soluble Contaminate Out Of Water

    One such way of removing caffeine includes distillation, distillation is possible between the two as they have a distance of over 50 degrees Celsius in boiling points. Water has a boiling point of 100 degrees Celsius and caffeine has a boiling point of 178 degrees Celsius. This means if the solution is heated to 100 degrees the water will begin to evaporate but the caffeine will not. The water vapours can then undergo condensation leaving pure water without the contaminate present. This process however can be time consuming and costly also requiring a constant heat source for prolonged periods.…

    7-Trimethylxanthine Research Paper

    Caffeine (1, 3, 7-trimethylxanthine) is one of the most important naturally occurring methylated xanthine alkaloids. It is a constituent of coffee, tea, sodas, chocolate, various energy drinks, and is the most widely consumed behaviorally active substance in the world. After rapid and complete absorption from gastrointestinal tract, caffeine undergoes extensive hepatic metabolism, mediated primarily by cytochrome P450 1A2 N-demethylation, to form three primary metabolites, paraxanthine (1, 7-dimethylxanthine), theobromine (3, 7-dimethylxanthine), and theophylline (1, 3-dimethylxatnhine). In humans, the formation of paraxanthine accounts for 83.9 ± 5.4% of caffeine metabolism, while theobromine and theophylline account for 12.2 ± 4.1 and 3.7…

    Acetanilide Extraction

    This lab was performed to both introduce and practice extraction techniques along with any procedures associated. The specific extraction employed used the different reactivates of the components with an acid and a base to produce products that are more soluble in water at different stages. Other methods included filtration of mixtures, obtaining a compound’s melting point, and using infrared spectroscopy to analyze a compounds structure. Since no initial masses were given, percent yield cannot be determined. However, a relative analysis of the resulting masses of the compounds shows that the solution contained mostly aspirin, caffeine, and acetanilide in decreasing amounts, but since each compound contains the other compounds, this conclusion…
