The creation of new approaches to the standardization of Proktofitol
The methodological approaches for standardization of antihemorrhoidal species (Proctophytol) were developed on the base of results of chemical investigationc of Frangula alnus Mill. barks. These approaches consist in the determination of anthracenderivatives by means of spectrophotometry at analytical wavelength 524 nm and using of frangulin A as standard sample. The contents of the total anthracenderivatives in species «Proctophytol» are varied with 3,50 % to 3,84% (calculated on frangulin A).
