Trigonelline is a naturally occurring alkaloid found in coffee beans, fenugreek seeds (Trigonella foenum-graecum, from which its name derives), and other plants. It is the N-methyl betaine of nicotinic acid (niacin) and serves as a key biomarker for coffee authenticity and quality.
Primary applications: Analytical reference standard, coffee quality marker, and research compound.

Q: What is the difference between Trigonelline and Nicotinic acid (Niacin)?
A: Trigonelline is the N-methyl betaine of nicotinic acid. It is a methylated derivative, not vitamin B3 itself.
Q: Why is Trigonelline used as a coffee quality marker?
A: Trigonelline content differs significantly between Coffea arabica (higher) and Coffea robusta (lower). It is a key indicator for coffee authenticity and grade.
Q: Is Trigonelline water-soluble?
A: Yes. Trigonelline is freely soluble in water.
