Abstract: The site-specific natural abundance deuterium distribution of raspbeerry ketone 3 obtained through a variety of methods has been determine through 2H NMR spectroscopy. This technique provided a means of distinguishing between 'natural' raspberry ketone biogenerated from 4-hydroxybenzalacetone 2, obtained from 4-hydroxybenzaldehyde of extractive botanical origin and acetone produced by sugar fermentation, by reduction using baker's yeast and other microorganisms from other raspberry ketone samples obtained in different 'non-natural' ways. Of 'natural' origin results also a commercial sample obtained in an unspecified manner. A mechanistic interpretation has been proposed to explain the difference of site-specific deuterium content between the examined samples.
