How Much Speciogynine is in Plants & Products?
Summary: A large profiling study (UPLC-HRMS) across US-grown plants and commercial products shows clear chemotypes and wide variation in indole alkaloids, including speciogynine—evidence that “kratom” is not compositionally uniform. This underlines the importance of validated quantification in quality control.
Key points:
Method quantified 8 indole and 6 oxindole alkaloids (speciogynine included) and mapped chemotype differences. PMC
For site users: always tie claims about effects or safety to measured composition (batch-specific COAs).
