Abstract
Relevance. Currently, there is an increased interest in medicinal plants and preparations from natural herbal raw materials. This is due to the fact that biologically active substances of plants are more easily included in vital processes and do not cause side effects in humans. They can be products of primary (vitamins, fats, carbohydrates, proteins) and secondary biosynthesis (alkaloids, glycosides, tannins). Plants always contain a complex of biologically active substances, but one or several have a therapeutic and prophylactic effect. They are classified as active ingredients and are used in the production of medicines. Some of the promising medicinal plants are species from the genus Dioscorea, for example, Dioscorea alata L., containing a complex of biologically active substances. The aim of this work is to study the effect of humidity and the level of mineral nutrition in the root environment on the accumulation of biologically active compounds in the tubers of the dioscorea winged plant, adapted to in vivo conditions on an ion-exchange substrate of various chemical composition and agrophysical properties.
Results. It has been shown that Dioscorea alata L. plants are able to accumulate the greatest amount of starch, dry matter, ascorbic acid, and flavonoids in an ion-exchange substrate modified with 1 g/l of the coarse hydrogel fraction. The data obtained can be used for practical purposes.
