Scientists developed a new way to help understand what happens in the body when people consume a plant product and the many chemicals it contains. The American Chemical Society’s Journal of Natural Products published the method to quickly analyze the effects of a natural product, developed at Emory University.
As a test case, the paper focused on biotransformation of chemicals from the kratom plant by human liver cells in a laboratory dish. The researchers developed an automated method — based on high-resolution mass spectrometry and molecular network mapping — to gain a detailed, big-picture view of the resulting metabolites, or chemicals produced.
The new, streamlined methodology can be broadly applied to nutrition and dietary supplement research, filling a critical gap in the field.
“Plants evolved extraordinarily complex chemical defenses and signaling systems,” says Cassandra Quave, co-senior author of the study and professor of dermatology at Emory School of Medicine and the Center for the Study of Human Health. “Our new approach in molecular mapping gives us a way to follow how that chemical complexity is reshaped by human metabolism.”
“Our technique does not just look at how one compound in this plant is metabolized,” adds William Crandall, first author of the study and a PhD student of molecular and systems pharmacology in Emory’s Laney Graduate School. “It shows how dozens of compounds are metabolized at one time.”
“This method marks a major, transformative step in natural products research,” says Dean Jones, co-senior author of the paper and professor in Emory School of Medicine. “A process that used to require years of work now takes just days.”
