摘要: A UV-Vis spectrophotometric method for characterization of plant extracts with specific acid dissociation constants was developed and nine traditional Chinese were used in the analysis workflow. The ionization gave intensive pH-dependent spectral shifts their changes differed between wavelength ranges. simulation one-step two-step processes showed that distributed steadily at some These might be as markers extracts. This study suggests proposed has potential applications quality assessment mass control food pharmaceutical industries.
