“…Thus, the acid complex of plantain leaves is represented by: fumaric, oxalic (31-103 mg%) [4], tartaric (1.60-1.87%), citric (1.22-1.53%), malic (0,20-0.51%), malonic (0.11-0.35%) and succinic (0.25-0.55%) acids. The total content of organic acids is 10-12%, of which up to 60% are related [5].…”

Introduction. Implementation of scientifically sound use principles of dairy and plant raw materials with functionaltechnological properties is relevant. Materials and methods. Normalized milk was used as the raw material to obtain protein concentrates. As a coagulant in the deposition of proteins used juice of direct extraction from the terrestrial part of Plantago major L. Identification and quantification of polyphenols and flavanoids in the samples of the plantain juice and the obtained whey was performed by high-performance liquid chromatography using system Prominence LC-20 Shimadzu (Japan). Comparisons were made with external standard samples. Results and discussion. The study of the qualitative composition and quantitative content of polyphenols and flavonoids in protein-plant concentrates obtained by deposition of milk proteins with the juice of direct extraction of the terrestrial part of Plantago major L were presented. The process took place at elevated temperatures. According to the analysis of absorption spectra of the experimental samples of juice from the plantain found that the maximum is at wavelengths of 225-350 nm. This result is correlated with the fact that of the 22 isolated flavonoids, 9 substances are 6oxyflavones, characterized by a maximum within the range of 255-285 nm. The difference between the content of polyphenols in Plantago major L. juice and whey indicates the degree of transition of polyphenolic compounds into protein-plant concentrates. The total content of flavonoids in all tested samples was equal to the content of substances that were similar to the standards of flavonoids (phenolic acids, catechins, flavonols, flavonones and flavones) with the exception of catechin-like substances. Flavonols are represented by the glycosides of myricetin. Naringin and hesperidin are part of flavonones. The flavones in the quantitative sense are of the lowest weight and are represented by luteolin and its glycosides and glycosides of apigenin. Phenolic acids content ranged from 12.36 mg/l for plantain juice and 0.07 mg/l for colored whey. Conclusions. The degree of polyphenolic compounds transition in protein-plant concentrate was determined at the level-77% of the total amount, of which 74% are flavonoids.

“…Plants are traditional sources of various biologically active compounds, many of which so far have not been well studied or characterized [1,2], e.g., compounds that affect such important biological processes as migration, adhesion, differentiation and proliferation. Of special interest is the research into a new group of biologically active plant bioregulators, membrano tropic homeostatic tissue specific bioregulators (MHTB), that were found in various tissues of verte brates and fungi [3].…”

Peptide mixtures with molecular weights of 1000-2000 Da and in vivo membrano trophic activity against mouse hepatocyte culture at very low concentrations were isolated from dill Anethum graveolens L. leaves. It has been found that plant peptides in aqueous solution formed larger nanosized particles of approx imately 90 nm with a secondary structure mainly composed of β structures and random coil structures. We demonstrated that peptides isolated from A. graveolens in vitro at an ultra low dosage affected the size of the area of pigmented cells of amphibian liver, which are analogous to Kupffer cells of the mammalian liver, using roller organotypic newt liver culture models.

“…IR spectra were recorded in films on KRS-5 plates on a Spectrum 100 (Perkin-Elmer) IR-Fourier spectrometer in the range 4000-650 cm -1 . Carbohydrate content was determined by the anthrone method [8]; protein, by the literature method [9]; ash content, gravimetrically after ashing; galacturonic-acid content (K GalUA ), by reaction with 3,5-dimethylphenol [10]; free (K f ) and esterified (K e ) carboxylic groups, by potentiometry [11]; and acetyl content (K Ac ), by the hydroxylamine method [12] and IR spectroscopy [13]. The lignin content in HC was determined by the Komarov method [14].…”

Bearberry [Arctostaphyllos uva-ursi (L.) Spreng., Ericaceae] is an official medicinal plant used in medical practice to treat a broad spectrum of diseases of the urogenital tract [1]. The active compounds of A. uva-ursi are phenolic glycosides, tannins, and flavonoids [2]; other classes of compounds are insufficiently studied. Considering the fact that the forms of A. uva-ursi used most often are aqueous extracts (decoctions, tinctures, and dry extracts obtained from aqueous extraction), we analyzed water-soluble polysaccharide components and pectinic substances in addition to hemicellulose of this type of plant raw material.Water-soluble polysaccharides (WSPS) were isolated from ground leaves of A. uva-ursi (200 g) by successive extraction in a Soxhlet apparatus using CHCl 3 , EtOAc, and (CH 3 ) 2 CO, after which the raw material was worked up exhaustively with water at 20 and 100°C. The extracts obtained at the different temperatures were concentrated separately and dialyzed through a cellulose-acetate membrane (Filtrak) against distilled water. The undialyzed remainder was precipitated by acetone (1:5). The resulting precipitates were centrifuged, demineralized by cation-exchanger KU-2-8 (H + -form), and deproteinized using pronase from Streptomyces griseus (Sigma) [3] to produce two fractions of water-soluble polysaccharides, WSPSc and WSPSh in yields of 0.708 and 0.512 g.WSPSc was a heterogeneous fraction that contained at least three components according to gel chromatography. The reaction with iodine was negative. The IR spectrum exhibited strong absorption bands for an α-bond (762.7 and 852.
