Β Carotene

The objective is to standardize the content of β-carotene – one of the principal active substances with sufficient hypolipidemic activity in the resultant original product. Search for natural biologically active substances having a hypolipidemic effect is one of the topical questions in modern pharmacy. Most of the research is carried out by means of isolating individual substances from the plant object. We propose to study a native phytocomplex obtained from pumpkin pulp – a dry extract of pumpkin pulp juice. The following materials and methods were used: laboratory-obtained dry extract of pumpkin pulp juice and methods used to determine the qualitative and quantitative content of β-carotene in an individual substance. It was possible to adapt the methods applied to the analysis of an individual substance in relation to the resulting phytocomplex containing both lipophilic and hydrophilic fractions. The rapid method of quantitative determination of β-carotene described in the scientific literature was corrected. An effective alternative method for spectrophotometric determination of β-carotene in the phytocomplex has been developed. Phytocomplexes standardized for the main active substances can be used to obtain effective drugs and biologically active additives with minimal side effects. In addition, the expansion of the search for alternative natural objects containing complexes haaving a hypolipidemic effect is currently relevant. Based on the literature data, in the future it is planned to conduct a pharmacological study to establish the anti-inflammatory effect of the resulting complex on the state of the vascular wall.

The paper presents a comparative assessment of the nutritional value depending on the phenological phase of Onobrychis viciifolia Scop., as well as the determination of the regularity of the accumulation of biologically active substances and heavy metals in the herb of the species. The yield of green mass of plants was determined. From each hectare of sowing, 9,7 centners of protein can be obtained; the yield of fiber is 13 centners, BEV is 22,9 centners, fat is 1,6 centners, ash is 4 centners and carotene is 13.0 kg. Depending on the growing season, the chemical composition in the grass of Onobrychis viciifolia changes. The content of calcium, phosphorus increases, and the presence of iron, copper, cobalt, zinc, manganese and molybdenum and amino acids decreases.

An analytical method for the quantitative determination of antioxidant sodium metabisulphite in veterinary drugs has been proposed by spectrophotometric method. Based on the literature data, the optimal conditions of the analytical reaction were selected experimentally. The dependence of the value of the analytical signal on the temperature of the reaction medium, concentration of p-rosaniline and duration of the reaction was investigated to establish the optimal conditions of the analytical reaction and obtain a stable analytical signal. The stability of the colored analytical form in time was also checked and the linear dependence of the value of the analytical signal on the concentration of sodium metabisulphite was investigated. The analytical reaction at room temperature is optimal. The maximum analaytical signal is achieved by carrying out the analytical reaction for 10 minutes and then practically does not change for an hour. To achieve the maximum analytical signal, it is necessary to use a 20-fold excess of dye relative to sodium metabisulphite. The analytical signal remains stable only for the first hour, then gradually begins to decrease. Metrological characteristics of the method of determination of metabisulphite in veterinary drugs are calculated, the limits of spectrophotometric determination are 0.33 – 2.50 μg/ml. The correctness of the developed method was checked on model solutions by the method of "introduced-found" method of comparison in the presence of various biologically active substances that are part of drugs together with sodium metabisulphite. The content of sodium metabisulphite in veterinary drugs of domestic and foreign production at different intervals of their storage time was established. It is shown that the content of sodium metabisulphite in drugs decreases during their storage time, until complete disappearance, which directly affects the content of the active substance, because in the absence of antioxidant oxidative processes with biologically active substances begin to take place.

Introduction. The perspective direction in therapy of dyslipidemia (DLP) is a complex application of biologycally active substances from marine hydrobionts. Objective. The purpose of research - to compare the lipidcorrective action of preparates based on biologically active substances from marine hydrobionts - fukolam and maristim - individually and in combination with atorvastatin in patients with DLP. Materials and methods. 250patients with DLP and 40 healthy donors were included in research. As medicines atorvastatin, fukolam, maristim were used. In the blood serum the levels of lipid spectrum were determined. Results. Hypolipidemic action of fukolam in complex of basic therapy of patients with DLP was implemented by gradually reducing the total cholesterol, cholesterol of low-density lipoproteins, triglycerides levels to control values. The efficacy of fukolam was comparable with that of atorvastatin in a daily dose of 10 mg. Complex of «fukolam-maristim» showed hypolipidemic effect in severe hyperlipidemia. Conclusions. Combined therapy with use of bioactive substances of natural origin may be one of the way to improve the efficiency of hypolipidemic therapy. We have developed the algorithm of differential correction of DLP by inclusion the fukolam and maristim in complex therapy.

General information about biologically active substances flavonoids is concisely presented. The need for the quantitative determination of its content in products and the influence of product processing on flavonoid’s content is justified. Methods of qualitative and quantitative determination of flavonoids content in various products, medications and raw materials were studied. Based on this study the method of quantitative determination of flavonoid’s in samples of irradiated coriander is compiled and tested. Further ways to improve and adjust the compiled method for flavonoid’s content determination in irradiated samples via spectrophotometric analysis is considered.
