Studies on the Spectra of Protoberberine Alkaloids. I. Absorption Spectrum of Berberine

Croatica Chemica Acta, 1965
Measurements have been made of the visible and UV absorption spectra of berberine chloride in pure aqueous, methanol, ethanol and propanol solutions and in the presence of various concentrations of either hydrochloric acid or potassium hydroxide. In all solutions, potassium hydroxide considerably influences both the form of the absorption curves and ...
