Extract Caffeine From Tea

- Caffeine is a natural stimulant most commonly found in tea, coffee and cacao plants.”

As previously stated, the following are the calculated RF values for each plate, Plate 1: Acetaminophen; Acetaminophen (Isolated)- 4.0/6.9= 0.57, Acetaminophen (Pure)- 3.8/6.9=0.55, Excedrin- 4.2/6.9=0.61 Plate 2: Caffeine; Caffeine (Isolated)- 1.9/6.8=0.28, Caffeine (Pure)- 0.8/6.8=0.12, Excedrin-4.0/6.8=0.59 and Plate 3: Aspirin; Aspirin (Isolated)-6.2/7.5=0.83, Aspirin (Pure)-6.2/7.5=0.83, Excedrin-6.8/7.5=0.9. The yield of each isolated analgesic was not calculated. The Rf values of the isolated acetaminophen, pure acetaminophen and Excedrin were all within 0.06. This is most likely due to the contamination of the TLC plate with Excedrin. During plating, drops of the Excedrin solution may have been introduced to the plate. Also, the capillary tube may have been contaminated. This lead to nearly identical marking on the TLC plate and similar Rf values. Due to this, it is not possible to conclude whether or not acetaminophen was separated from the sample of Excedrin. The Rf value of the pure isolated caffeine was 0.28. This was 0.16 higher than the Rf value of the pure caffeine. Although the value of the isolated caffeine is nearly double that of the pure caffeine, it appears that caffeine was separated from Excedrin, but the sample was not pure. It still had other analgesics present. This is concluded from the location

More than 90% of high school students in America suffer throughout the school day because of chronic sleep deprivation. Students, parents, teachers, and doctors have begun to question the start times of schools and their effect on students. Schools may begin early to allow time for extracurricular activities and sports practices at the end of the school day. By beginning earlier, students and teacher get home earlier. But overtime, early start times have developed negativities in the lives of adolescents. While some administrators are concerned with schedule changes, it is proven that current school start times can damage a student’s learning environment, the sleep deprivation developed can lead to larger health risks, and the consumption of

In this experiment, extraction was used as a separation technique to separate the acid, base, and neutral compounds. In extraction, two immiscible solvents with opposite polarities are used to dissolve different parts of the solute with different polarities, so they form two distinct liquid layers. In this experiment, methanol, an organic solvent, and an aqueous solution were used as the two immiscible solvents. The extraction solvent must also be capable of dissolving one of the mixture components. While initially it seems as though methanol, an organic solvent would be incapable of dissolving a polar acid or base, the conjugate of the acidic and basic compound will dissolve in methanol. The conjugate acid and base were obtained by adding

With the constantly increasing paces of everyday life the search for an energy source, capable of boosting the human body to new limits by extending its endurance, continues. In the recent years a specific product, called an energy drink, has received much publicity worldwide. The energy drink is a highly caffeinated stimulant that is able to rise the performance of the human body. Many people consider it as a refreshment after a hard day’s work. What’s more one of the most frequently used cases of energy drinks is in combination with alcohol during parties. However, the majority of consumers do not understand the way they work and often abuse with the consumption of the substance. Furthermore, a great amount of them are unaware of what effects can be caused on the human body.

The chloroform and caffeine mixture was collected and into a conical flask labeled A. The remainder of the solution was discarded. This was repeated for beakers B and C.

Caffeine is a chemical found naturally in few plants all over the world. From these plants it is processed into its pure form and then put into other things such as soda, energy drinks, tea, and pills. Energy drinks and soda are some of the most widely marketed products in the world, even though they contain the highest concentration of caffeine outside of pure caffeine supplements. It is a stimulant that affects everyone in strange but semi predictable ways. Research has been done on this topic since the 1920’s and many different conclusions have been reached. In modern schools of thought, caffeine has been found to be a lightly addictive, moderate to severe stimulant that affects neurological function in various ways, though scientists disagree

Studies show that caffeine can increase the speed at which athletes can run. It is a strategic, legal stimulant to help your speed. More than two thirds of Olympic runners drink a caffeinated drink to help their performance. For long events such as marathons and half-marathons, caffeine is shown to reduce the athlete’s perception of effort. Caffeine can also increase mental alertness and improve your mood. Basically, it makes running seem easier. Additionally, it makes fat easier to use as an energy source. This conserves the ‘burning’ of glycogen, which can improve performance in the last legs of the race. Although researchers are not positive why caffeine makes fat easier to use as an energy source, they know that as caffeine levels in the body increase, the concentration of fat in the bloodstream increases, which makes it easier for the body to utilize the fat and use it as energy. Reaction time, coordination, and performance in heat are also affected after the ingestion of caffeine. A recent study on the effect of caffeine on athlete’s performance in heat showed that athletes that ingested caffeine before running in high temperatures completed 15-23% more work than those who used water or another widely used sports drink. Caffeine can also help athletes recover after a sporting event, when used with carbohydrates. Research shows that drinking a beverage with both caffeine and carbohydrates in it rebuilds glycogen 66% faster than a regular drink with only

In chapter eight, caffeine, Natterson beings by defining what caffeine is and how popular it 's become. The natural stimulant, caffeine, is found in several plants such like the tea bush, the coffee plant, the cacao tree, and the kola tree. When a person consumes caffeine, it affects the neurons in their brain causing the feeling of energy and awakeness. This happens because the neurotransmitter, Adenosine, is meant to control and us down; but when it meets caffeine, caffeine

These results oppose the theoretical action of caffeine, which inhibits the action of adenosine by blocking its receptors to increase neural activity. As caffeine acts as a competitive inhibitor to block adenosine from binding, an increase in the concentration of caffeine molecules should result in an increase in the number of adenosine receptors which are blocked by caffeine. Thus, fewer adenosine molecules should be able to bind and so a decrease in its effects; drowsiness, fatigue and mental alertness, is expected to occur. Thus, it is expected that the subjects who drank 100% caffeinated beverages experience faster reaction times than those who drank the 50% caffeinated

There are over 60 plant species that produce caffeine naturally. Coffee beans, guarana, tea leaves and coca beans are a few plants that contain natural caffeine. The caffeine in these plants are used as a natural pesticide to paralyze and kill insects that desire to feed on that plant. These plants are then harvested and the caffeine is extracted out of these plants for humanity to use. Coffee, tea, and chocolate are some examples of natural caffeine. Distinguishing whether a product is a natural or synthetic caffeine can be tricky, but if it is natural, the ingredient label will name the actual plant where the caffeine can be found (Whidden)

Some people just do not care about their health. Although a lot of studies have been done to prove the terrible effects caffeine has on the human body, American citizens still take in a disgusting amount of caffeine every day. Do people today really care so little about themselves, or are they just plain stupid and unaware of the disaster they are wreaking on their own bodies? Caffeine is really just a poison that energizes you for a little while. An argument written in a belligerent style offends readers and causes them to stop reading,

We hypothesize that if caffeine levels are increased, then time taken to run a lap will decrease when time is a function of caffeine level. Because of this and the fact that Dr. Pepper has more caffeine, we believe that when we give the test subjects the Dr. Pepper they will run the fastest. McDonald 's sweet tea contains 12.5 mg of caffeine per 118.3 ml, Dr.Pepper contains 33.3 mg of caffeine per 118.3 ml, and of course water contains 0.00 mg of caffeine per 118.3 ml. We have reason to believe this will be the result based on other experiments done that prove that caffeine improves reaction time and agility.

Metabolism is the sum of all anabolic and catabolic reactions within a living organism to sustain life. The energy required to perform these reactions is provided by oxygen in the form of ATP, therefore the oxygen consumption rate can be measured to determine the metabolic rate. Since oxygen is obtained through respiration, the efficiency of an organism’s respiratory system affects its metabolism. Previous studies have shown that caffeine affects the human respiratory center and occasionally dilates bronchus. It can thus stimulate human respiration and increase the metabolic rate (Haggins et al, 1915).

In today 's society, if we appear to be exhausted, while knowing that we have to be on the run, we turn ourselves to energy drinks. Little do we know that every time we consume a single sip of an energy drink, we are literally creating a crucial complication towards our body. The innumerable quantities of caffeine and sugar that we devour stimulates each and every part of the body. Individuals have been replacing protein bars and other athletic beverages for real food (McCarthy). Becoming addicted to energy drinks relates to type 2 diabetes, even long-term effects such as heart issues, but most of all death. It is urgent that we pace the amount of caffeine from energy drinks that we ingest on a daily basis.
