Abstract
The peculiarity of solid bodies of organic origin, in
contrast to solid bodies of mineral origin, is that their internal
structure is characterized by the presence of two spaces –
cellular and intercellular. Such bodies tend to swell upon contact
with the extractant. The phenomenon of swelling, during
extraction, is always accompanied by the dissolution of target
substances contained in the cellular and intercellular space. All
these processes create conditions for the diffusion of the
dissolved target substance through the cell membrane into the
intercellular space, and then through the intercellular space
beyond the boundaries of the solid phase particle. This helps to
increase the volumes of the cellular and intercellular
environment. The absolute value of the volumes of cellular and
intercellular spaces is one of the most important values when
developing and calculating extraction processes and forecasting
environmentally safe technologies for obtaining biologically
active compounds. The work presents a method of
experimentally calculating the volumes of intercellular and
cellular spaces of medicinal plant raw materials of various
morphological organs. The established absolute values of the
volumes of the cellular and intercellular spaces make it possible
to calculate the order of diffusion coefficients of biologically
active compounds in the medium of the intercellular space, as
well as in the cell membrane. In the future, the determined
values of the volumes provide grounds for predicting the
regime, kinetics and dynamics of extraction of target substances
during the implementation of an environmentally safe
technology for obtaining biologically active compounds in
production, as well as to support the monitoring of production
processes of extraction in digital mode.
