Abstract

Plants are natural sources of bioactive compounds, and the intensive use of wild plants to obtain them, in particular secondary metabolites, depletes natural biocenoses. Instead, modern biotechnological methods, especially cell and tissue culture in vitro, make it possible to get environmentally friendly, highly productive plant raw materials that are able to synthesize and accumulate specialized substances, which are valuable for pharmacology, cosmetology, and medicine. Regenerating in vitro-plants of different plant species such as Acorus calamus L., Phalaenopsis sp. were obtained in our research. It was proved that by changing the cultivation conditions it is possible to change the content of substances of secondary metabolites in explants and in the nutrient medium under aseptic culture.

Highlights

Constant changes in environmental conditions necessitate changes in the biochemical and physiological processes of all living organisms in order to increase their adaptive capacity
Quantitative analysis of secondary metabolites content showed a steady increase in the content of phenolic in the nutrient medium used for cultivation of Acorus calamus L. (Fig. 4)
The amount of xanthones in the nutrient medium decreased significantly over the same period of time, and the content of flavonoids was too low to be detected by a quantative analysis We identified a different composition of xanthones depending on localities of explants that were cultivated on this medium (Fig. 10 and Fig. 11)

Summary

Introduction

Constant changes in environmental conditions necessitate changes in the biochemical and physiological processes of all living organisms in order to increase their adaptive capacity. Numerous mechanisms of adaptation to the action of abiotic, biotic and anthropogenic factors specify unique properties of plants. Plants synthesize hundreds of thousands of organic compounds, which are divided into three main groups. The first group includes primary metabolitescompounds that are directly required for plant growth. The second onephytohormones, which perform a regulatory function in the plant body and metabolism in general. Scientists attribute organic substances with relatively low molecular and high biological activity, namely substances of specialized metabolism. The other name for this group of substances is secondary metabolites [1, 2]
