INFLUENCE OF ENVIRONMENT AND HYDROPHOBIC SILICA ON WATER BINDING IN COMPOSITES CONTAINING MILLED MEDICAL PLANTS

The aim of the work was to study the effect of methylsilica additions and deuterochloroform hydrophobic medium on the water state in a phytocomposite system “Lymphosilica”. The water state in a Lymphosilica composite material, created by mechanochemical activation of a mixture of milled medicinal plants and wetting-drying silica A-300 was studied by low-temperature 1H NMR spectroscopy. The parameters of bound water layers in the initial composite and hydrated mixtures with methylsilica in air and hydrophobic media were measured. It was shown that liquid and solid hydrophobic agents reduced the water binding with the cellulose components of medicinal plants. This can be used to control desorption rate of the bioactive complex for oral and transdermal use such herbal biological active components.
