In recent years, the fluorescence properties of pumpkin seeds have been highlighted on social media. When illuminated with a UV lamp, pumpkin seed extract appears orange/red to the human eye due to fluorescence associated with protochlorophyllide that is present in the seeds. Chlorophyll extracts can also be used as a fluorescent dye in “glowstick” chemiluminescence experiments. The similarities between chlorophylls and protochlorophyllide raised the question, is it possible to use pumpkin seed extract as a fluorescent dye in chemiluminescence experiments? In this short article, some results are reported from attempts to use pumpkin seed extracts for chemiluminescence experiments.
