Abstract
Using the collections containing 6 types of plant materials (Rhizoma Potentillae, Herba Hyperici, Fructus Foeniculi, Flores Chamomillae, Herba Plantaginis Majoris, Rhizomata et radices Inulae) are developed medicine forms of biologically active additions in the form of tablets and capsules, as well as the packages in filter parcels. The process of the conversion of tanides and flavonoids sums from medicine forms into solutions simulating the environment of the stomach (0.1 g-eq / L hydrochloric acid solution) and the intestinal environment (sodium phosphate buffer solution pH = 8.5–8.6), was studied. It is shown that the degree of extraction is quite high, and it allows the use of their 2 forms possible. In the case of applying parcels, the quantity of tanids sum conversion is lower.
