biologically active substances

The results of the study of the chloroform extract of the herb Ranunculus acris L. are presented, in particular the content of biologically active substances and antioxidant activity. 33 volatile compounds were identified: fatty acid esters, higher fatty acids, saturated hydrocarbons (alkanes), monocyclic and bicyclic monoterpenoids, etc. It was established that the chloroform extract has an antioxidant effect. In addition, the significant content of biologically active substances in the lipophilic volatile fraction of Ranunculus acris L.

Crocus sativus (saffron) contains biologically active substances and is used in the food and cosmetic industries. With the preservation of plant diversity in nature, the biotechnological method of tissue culture was used and the plant was introduced into in vitro conditions. The influence of the composition of the nutrient mediumon the growth of biomass and production was studied. The best results were obtained with the use of growth regulators benzylaminopurine (BAP) and naphthylacetic acid (NOK) in the amount of 20 μmol/l BAP + 15 μmol/l NOK. Cultivation time was 12 weeks.

Grape is one of the oldest plants used by man. It has a special taste and is in great demand around the world. It is mainly used by the food industry, and by-products of winemaking are actively used in cosmetic and pharmaceutical industries, due to its composition. Grape production wastes - components of the vine are suitable for further use for the extraction of valuable biologically active substances and increase the competitiveness of primary and secondary winemaking.
