Santos-Torres worked with SIU researchers Mary and Gary Kinsel to use analytical instrumentation to examine various CBD products, including tinctures, topicals, gummies and pet treats, and their active ingredients. Together, the research team used liquid chromatograph mass spectrometers to separate the CBD from the other ingredients in the products and compared them against five standard CBD solutions.
“Roberto took the two types of data, measured the area of the CBD signals and calculated the amount of CBD using the standard calibration equations,” Mary Kinsel said. “We repeated the extractions up to three times to calculate an average amount of CBD for the CBD consumer products.”
Another SIU physiology student, Chloe Leonard, will continue the work this semester. Leonard’s first task is to validate the research team’s extraction processes and then continue to examine CBD products.
“It is problematic when the public cannot trust that
