title: [Spectroscopic study on procaine hydrochloride and its cyclodextrins inclusion complexes].
abstract: In this paper, by means of the ultraviolet spectrum of procaine, we showed the existence of two types of procaine (molecular and ion types) and determined their pH values. The variations of fluorescence intensity of the two types in the presence or absence beta-CD, HP-beta-CD and Methyl-beta-CD were studied.
