Caffeine is a mild stimulant that occurs naturally in at least 63 plant species. Caffeine can be found in the leaves, stems, seeds, and roots of these various plants. Caffeine is part of the methylxanthine family. It consists of a xanthine molecule with three methyl groups attached to it.

Caffeine is an odorless, slightly bitter solid. It is a stimulant. Caffeine dissolves in water and alcohol, and has crystals that look like needles. When taken in small

Components containing caffeine were composed into stock solutions. These solutions were diluted to 1: 10 substance: mobile phase. A stock solution of caffeine was diluted 1:50. A sequence of diluted caffeine solutions were prepared for use as a standard (ppm): 1, 2, 4, and 10. Solutions of acetaminophen, acetylsalicylic acid, and Goody’s Powder were developed to differentiate chromatographic peaks observed. These solutions were subjected to HPLC for examination of the observed peak area and retention time for the set of compounds. Comparison of retention time allowed for the differentiation of peaks observed. The peak area obtained was utilized to determine the relative concentration of caffeine present in Goody’s Powder based on the relationship obtained in the standard. The content of caffeine present in Goody’s Powder by percent weight was identified.

According to Stromberg, “Caffeine closely resembles a molecule that’s naturally present in our brain, called adenosine, Normally, the adenosine produced over time locks into these receptors and produces a feeling of tiredness.” When people decide to withdraw caffeine it usually gives them headaches, affect their sleeping behaviors, cause nausea, and feel flu like symptoms. According to Science behind food and cooking in the kitchen,“People have used caffeine since the Stone Age. Early people groups found that biting the seeds, bark, or leaves of specific plants had the impacts of facilitating weakness, empowering mindfulness, and hoisting mind-set.
