[Technology of extract improving the immune system].

The article deals with the production of the extract of Echinacea purpurea herbs when selecting an extractant concentration, the size of particles in a raw material and the method of extraction. Using 60% (v/v) ethanol for production of the immune system enhancing extract, the extract becomes green due to pigmental substances; therefore, 60% (v/v), 70% (v/v), and 96% (v/v) ethanol was not used for extraction. It is recommended to use 50% (v/v) ethanol for extraction.

[Technology and analysis of "Askoeziuofito" tablets].

The objective of this work is to produce chewable tablets out of Echinacea purpurea liquid extract (1:1) and ascorbic acid: to create the technology, to select methods of analysis and to examine stability. The paper describes the technology of tablets: a method of condensation is chosen; the influence of additional substances over tableting is established; pressing characteristics of tableting mixtures are examined. The quality of tablets is evaluated in terms of appearance and technological rates: average tablet mass, hardness against pressure, hardness against wearing, time of disintegration, and speed of ascorbic acid secretion.

[Development of "Saules" tincture technology].

The article deals with the production of the "Saules" tincture in a way of selecting an extractive agent concentration, the size of particles of the raw material and the method of extraction. The experiment indicates that the optimum concentration of ethanol in the tincture is 70% V/V, the particles' size is in the range from 1 to 2 mm; the production method recommended for use is percolation. The quality of the tincture was evaluated by determining the quantity of flavonoids and dry residue, the concentration of the ethanol, the density and the microbial contamination.

[Development and analysis of revitalizing tincture].

The article deals with the production of the complex tincture of Hyperici herba 80.0 g, Cinnamomi cortex 20.0 g, Rosmarini folium 20.
