Catalpa seeds contain up to 30% of eleostearic acid. Decoctions are made of the bark of the tree. They serve as a gastric agent and have an anthelmintic effect. Decoction of the bark exhibits bronchodilator action, is used in the complex treatment of cancer. The leaves are used to treat skin diseases. The infusion of fruits has anti-herpetic and hypoglycemic properties. The aim of the work is to investigate biologically active compounds of the leaves of catalpa bignini. The object of the study was the leaves of common catalpa harvested in the summer of 2018 in Sevastopol. Chemical identification reactions and methods of chromatographic analysis were used to determine the major groups of biologically active substances of the leaves of the catalpa (chromatographic paper Filtrak FN No. 4, Munktell, Czech Republic). Chromatography was performed in pre-selected solvent systems: n-butanol‒acetic acid‒water (BAW) (4:1:2) ‒ I direction and 15% acetic acid ‒ II direction. Identification reactions were performed with aqueous and aqueous-alcoholic extracts of catalpa leaves. The qualitative composition of the phenolic compounds was investigated by paper chromatography. The content of the sum of phenolic compounds, hydroxycyclic acids and flavonoids was determined by the spectrophotometric method. Based on the held reactions and chromatographic analysis, by the characteristic fluorescence in the filtered UV light before and after treatment with chromogenic reagents and the values of Rf in the raw material the presence of the following groups of biologically active substances were determined: flavonoids, phenol glycosides, hydroxycoric acids. According to the chromatographic analysis, at least 9 substances of phenolic nature have been detected in the alcohol-aqueous extracts. For the first time, the presence of the following groups of biologically active substances: hydroxycoric acids, phenologic glycosides, flavonoids was determined in the leaves of catalpa. Quantitative content of natural compounds in the leaves of common catalpa: the sum of phenolic compounds (4,76 ± 0,04%), of hydroxycoric acids (3,42 ± 0,02%), of flavonoids (1,88 ± 0,02%). The results of the study will be used in the development of the draft quality control methods for medicinal plant raw materials.

In this paper, the results of studies on the release of biological active compounds from their encapsulated forms under conditions of enzymatic hydrolysis in vitro are presented. In the phase of the model «small intestine» swelling of the capsules and their subsequent decay occurs, which allows to speak about the controlled release of encapsulated bioactive components. It was revealed that almost 90 % of the residual quantity of essential ingredients was released from the capsules in the model phase of the artificial «small intestine». At the end of the experiment, the capsules released all the encapsulated biologically active substances, regardless of the content of fish oil and phenolic compounds in them. It was noted that the poly-capsules had the greatest propensity to withstand the aggressive environment of the «model stomach» and concentrate in themselves the maximum amount of biologically active substances. Mathematical modeling confirms the direct transport of biologically active compounds and the role of the swelling of capsules in the release of biologically active compounds. two mathematical models describing the classical theory of diffusion from capsules and incorporating the material relaxation coefficient demonstrate a combination of empirical and theoretical approaches in controlling the properties of encapsulated biologically active substances. the obtained data are promising in the field of development of improved and functional food products, as well as the dry ingredients and concentrates

Micellar mediated extraction (MME) is a new and alternative method of obtaining biologically active substances, such as flavones, flavanones, anthocyanins, triterpene from plant material. In this study a series of polyethoxylated sorbitan esters of fatty acids (Tween 20, 40, 60 and 80) have been applied for the extraction of green tea containing Chrysanthemum morifolium flowers. Results showed that all tested surfactants were effective in the solubilisation of flavonoids and phenolic compounds. Probably, because of too high hydrophilicity, Tween 20 was not sufficient to obtain antioxidants, in contrast to another Tween. It has been shown that method is economical, attractive and ecological.
