General description

Palmatine chloride hydrate (Palmatine) is an alkaloid. It is a potential phototoxin, and exhibits low quantum yields for fluorescence. Normal Raman spectra and DFT calculations of palmatine chloride hydrate is reported.

Application

Palmatine chloride hydrate (Palmatine) is suitable for use:
  • as alkaloid standard in the method validation for determination of berberine, hydrastine and canadine in goldenseal (Hydrastis canadensis L.) root powder
  • in the preparation of 8-heteroaryl-7,8-dihydroprotoberberine
  • in a study to investigate the FT-Raman and surface-enhanced Raman scattering (SERS) spectra of three related alkaloid dyes, namely palmatine, jatrorrhizine and coptisine

Adducts of the quaternary protoberberine alkaloids (QPA) berberine, palmatine, and coptisine were prepared with nucleophiles derived from pyrrole, pyrazole, imidazole, and 1,2,4-triazole. The products, 8-substituted 7,8-dihydroprotoberberines, were identified by mass spectrometry and 1D and 2D NMR spectroscopy, including (1)H--(15)N shift
