## 3 Results and Discussion  
Preliminarily investigations on the physicochemical properties of the selected polyorganosiloxanes were carried out. The results were compared with the traditional extractants (water and 70% of aqueous alcoholic solution), as shown in Table 2.  
Table 2 shows that the studied polyorganosiloxanes possess low surface tension (from 18.54 to 27.12\(\cdot 10^{3}\) N/m) compared with those of a water-alcohol mixture (30.96\(\cdot 10^{3}\) N/m)

and water (72.40\(\cdot\)10\({}^{3}\) N/m). Compared to traditional extractants, silicones are characterized by high degrees of spreading and wetting. These characteristics are crucial for the extraction process. Then, we determined the qualitative (Table 3) and quantitative (Table 4) composition of silicone extracts of calendula and wormwood. We focused on the detection and quantification of biologically active molecules, including vitamins, flavonoids, tannins, terpenoids, and glycosides (Tables 3 and 4). According to Table 3, it can be argued that the studied polyorganosiloxanes are able to extract biologically active substances from plant raw materials of calendula and wormwood. The presence of vitamins A and E in the samples of silicone extract taken from amodimethicone BRB 1288 should be noted. These results can be explained by the presence of cetrimonium chloride and tridecet-12 in the mixed polymer BRB 1288 surfactants, which significantly increase the wetting and permeability of silicone. The absence of glycosides in the silicone extracts of wormwood Silicone Oil 350 cSt and BRB PTM 20 can be related to the specificity of the chemical structure of these silicones. Thus, it can be concluded that the studied polyorganosiloxanes exhibited excellent extraction properties for biologically active substances contained in plants. Table 4 shows that the use of one-component silicones (polyddimethylsiloxane Silicone Oil 350 cSt, cyclopentassiloxane BRB CM 50, and phenyltrimethicone BRB PTM 20) and a mixed solution of dimethiconol in cyclopentasiloxane BRB 1834 does not promote the extraction of vitamin C from raw materials. The use of amodimethicone silicone BRB 1288 allows for the extraction of vitamin C (15.72 g/L) with an efficiency similar to the aqueous
