High Performance Liquid Chromatography (HPLC) Method of Nordihydrocapsaicin Capsaicin and Dihydrocapsaicin. Capsaicinoids (capsaicin, dihydrocapsaicin and nordihydrocapsaicin) are a group of phenolic alkaloids specific to the genus Capsicum and are comprised of a vanillylamine head and a fatty acid tail. Capsaicin, dihydrocapsaicin and nordihydrocapsaic can be retained and separated in HPLC using Newcrom R1 reverse-phase column isocratically. The method uses a simple MS-compatible mobile phase of acetonitrile (ACN) and water without the need for a buffer. The peaks can be monitored by low UV (210 nm), ELSD, CAD or LC/MS.
