Obtaining Biologically Active Compounds by Extraction of Valerian Roots

An effective method of obtaining biologically active substances from plant raw materials without changing their optical isomerism is extraction. The investigation results of achieving equilibrium conditions for isovaleric acid extraction from valerian roots and rhizomes are presented. The effect of the isovaleric acid chemical structure and extractant nature on achieving equilibrium conditions is shown.

Extraction Process of Intracellular Substance

In this study the mathematical model of the extraction process from plant material is developed, taking into account the anatomical structure of plant material, namely the presence of cellular and intercellular spaces. The solution of the model enables to determine its kinetic coefficients Dc, Dt, process conditions, and predict the kinetics of the extraction process implementation in practice.
