Abstract
Trigonelline can be determined in green and roasted coffee extracts by a ion chromatographic method on a single column filled with polybutad iene-maleic acid (PBDMA) coated on silicia, 2 mmol/L aqueous HCl (pH 3 ) as eluent and UV detection at 254 nm. The merits of the new method a re investigated.
