Photochemical and Photophysical Processes of N-Deacetyllappaconitine and Its Monohydrobromide in Aqueous Solutions

  • Published:
Chemistry of Natural Compounds Aims and scope

The photophysical and photochemical processes of N-deacetyllappaconitine (DAL) and its hydrobromide (DAL·HBr) in aqueous solutions were investigated. Their spectral parameters and fluorescence (FL) quantum yields were determined. The UV and FL kinetic functions during photolysis of aqueous solutions of DAL and DAL·HBr were obtained. It was shown that Br– did not affect the photochemical transformation rate of the alkaloid. The role of singlet oxygen 1O2 in the phototransformation of DAL and DAL·HBr was discussed.
