The title of my research, as stated above, is the Chromatographic Characterization of Bee Propolis and Pollen From Around the World. I have chosen to analyze and compare the components that make up bee pollen and propolis from several species with varying origins, developing an understanding for how the type of extraction methods will affect the gathered results. The purpose of this research is to distinguish between the results gathered from using different extraction methods, while understanding the importance of the extracted components. Moving forward, we would like to understand the different health benefits that propolis can provide for humans and which benefits relate to which chromatographically discovered components.
Before stepping into the wet lab and performing physical research, Dr. Elmer Mojica and I worked collaboratively to perform literary research in order to finalize my research question and methodology being used. We studied papers from several scientific journals, such as the Food Research International and the Journal of the Science of Food and Agriculture. In today’s society, the focus of what is being put inside the foods and products consumed by humans is so vast and significant. For this reason, I expect to achieve a fully developed understanding of which extraction method is best, along with which components are found in which species of bees. I can then use this to understand which components humans are consuming when they go to health food stores to purchase propolis and pollen.
The methodology being used to answer my research question varies depending on the extraction method being used. In chemistry, extraction methods are used to separate substances that they are mixed with. I used my literary research to fully understand the Soxhlet, microwave, sonication, accelerated solvent extraction, and simple extraction. I aim to compare these methods with one another. I will first be using dichloromethane and methanol to make solutions with the propolis and pollen. I can then inject these solutions into the machine known as GC-MS, or gas chromatography-mass spectrometry. This provides us with a visual representation of the spectrum. We can then use this, alongside a library, to analyze which molecules make up the propolis and pollen. Refer to Image 1.0 for footage of the first bee pollen that we have begun analyzing.
This semester has so far been successful with literary research and we have begun injecting samples into the GC-MS. We are looking forward to analyzing the results and successfully reaching our desired achievements to answer my research question.
