Propolis ‘Fingerprint' Helps Determine Geographical Origin

Geographical Traceability of Propolis by High-Performance Liquid-Chromatography Fingerprints
Food Chemistry, Volume 108, Issue 2, 15 May 2008, Pages 749-759

Abstract: A rapid fingerprint method was developed for investigating and inferring geographical origin of Chinese propolis by using high performance liquid chromatography–ultraviolet detection (HPLC–UV)…

Our results revealed that the presence or absence of specific peaks and similarity evaluation in simulative mean chromatograms among different regions could efficiently identify and distinguish Chinese propolis from different geographical origins.
