HPLC Method for Analysis of Carnosine (beta-alanyl-L-histidine) on Primesep 100 by SIELC Technologies

Carnosine is a dipeptide molecule with the chemical formula C9H14N4O3. It is synthesized from beta-alanine and histidine. It is a naturally occurring pH buffer. It is found in muscles and brain tissue, but is produced in the liver. Some use it as a nutritional supplement, but it can be used in topical applications to reduce wrinkles.
Carnosine (beta-alanyl-L-histidine) can be retained and analyzed on a mixed-mode Primesep 100 column with a mobile phase consisting of water, Acetonitrile (MeCN), and Trifluoroacetic acid (TFA). This analytical method can be UV detected at 215 nm with high resolution and peak symmetry.
