We studied the effect of an anthocyanin-containing complex from the fruits of S. aucuparia L. on doxorubicin-induced genotoxicity in bone marrow cells of C57BL/6 mice. The complex reduced the genotoxic effect doxorubicin in metaphase plates of bone marrow cells in 24, 48 h, and 10 days after the administration of the cytostatic. The mean number of single fragments and the fraction of cells with gaps and aberrant metaphases also decreased.
The results of studying the effect of the anthocyanin-containing complex from Sorbus aucuparia L. on the main indicators of erythropoiesis in the blood and bone marrow of mice with Lewis lung carcinoma against the background of doxorubicin administration were presented. It was shown that administration of the anthocyanin-containing complex from S. aucuparia L. to animals with the tumor prevented the development of anemic syndrome by promoting regeneration of the erythropoiesis after its depletion caused by single administration of a cytostatic agent.
Mountain ash (Sorbus aucuparia L.) is a prominent representative of phenolic medicinal plants. A widespread and cultivated plant, it has a sufficient raw material base not only of fruits, but also of other parts of the plant (leaves, flowers); it is a promising source of biologically active complexes for the development of new medical drugs. In the work, the content of the main groups of phenolic compounds in plant extracts from fruits, leaves and flowers of S. aucuparia L. was determined. Extracts were obtained using the original technology with acidified 95% ethanol. The content of the sum of phenolic compounds was determined, as well as the content of anthocyanins, flavonoids, phenolic acids, tannins. The effect of these phenol-containing complexes on the development of transplanted tumors (Lewis lung carcinoma, lung cancer-67) and the effectiveness of cyclophosphane treatment were studied. It was revealed that the use of plant complexes leads to a significant inhibition of the development of metastases in the lungs, as well as an increase in the antitumor and anti-metastatic activity of cyclophosphane in combined treatment. The new data obtained are of interest for further study of these phenol-containing complexes in order to create drugs based on them to increase the effectiveness of chemotherapy for malignant neoplasms.

Introduction. Lemna minor L. (duckweed) refers to the duckweed subfamily (Lemnaceae S. F. Gray) and widely distributed in ponds of Russia. Literature data confirm the possibility of harvesting significant volumes of this raw material in natural habitat and grown in aquaculture. The process of biosynthetic accumulation in duckweed fronds provides a variety of compounds with a wide spectrum of biological activity. Therefore, the use of raw materials Lemna minor L. is promising for the development of drugs and parapharmaceutical products. Thus, it is an urgent task to quantify active components of duckweed and standardize (determination of criteria for identification, quality and safety) plant material.Aim. Establish macro- and microscopic characteristics of raw materials and develop methods for the quantitative determination of the main groups of biologically active substances (BAS) for standardization of raw duckweed.Materials and methods. Samples of duckweed was collected in natural habitats of Western Siberia. Macro- and microscopic assay, HPLC, UV-spectrometry were used in research process.Results and discussion. Were established the criteria for identification of duckweed fronds by studying external (macroscopic) and microscopic features of raw material Lemna minor L. Was developed and validated the procedure of the quantitative determination of phenolcarboxylic acids in raw material Lemna minor L.Conclusion. The study of external (macroscopic) and microscopic features provided the criteria for identification of the raw material Lemna minor L. The technique for the quantitative analysis of polysaccharides using gravimetry does not need validation, because is a direct method of substance measurement. Was validated quantification method of phenolcarboxylic acids (in terms of chlorogenic acid) by criteria of linearity, repeatability, in-laboratory precision and accuracy. Was established quality criteria for identification and quantitative assay, which can be used in the draft for normative documents for medicinal plant raw material of Lemna minor L. «Duckweed fronds».
The composition of phenolic compounds of rowanberry (Sorbus aucuparia L.) fruit extracts prepared with 40% ethanol and 95% acidified ethanol was studied. The differences in the content of flavonoids, including anthocyanins, and phenolic acids were shown. It was found that the antimetastatic activity of cyclophosphamide was most efficiently increased by the rowanberry fruit extract in 95% acidified ethanol enriched in anthocyanins. The aim of the present research was to investigate the effect of hydroalcoholic extracts of rowanberry fruit on the development of Lewis lung carcinoma and the antitumor activity of cyclophosphamide and to reveal the most effective extract containing a phenolic complex for its further study as a promising drug.
The effects of Fructus Sorbi aucupariae extract, originally saturated with anthocyans, on the development of Lewis lung carcinoma and B-16 melanoma in C57Bl/6 mice and the efficiency of cyclophosphamide treatment were studied. Antitumor activity of the extract and potentiation of the antimetastatic activity of the cytostatic were demonstrated. Studies on melanoma B-16 model revealed an increase in the counts of stromal progenitor cells in the tumor node and their accelerated maturation after treatment with the extract. No effects towards the tumor stem and committed cells were detected.
The purpose of the study – to study the effect of polyphenolic compounds extracted from the flowers of safflower oil and calendula, the functional activity of immune cells in cytotoxic immune suppression.Conventional methods determined the total number of splenocytes, relative (%) and absolute (106), the number of antibody-forming cells (AFC) in the spleen of mice by local hemolysis by Cunningham.Evaluated the effect of compounds of natural origin on the cellular immune response in the delayed-type hypersensitivity (DTH). Phagocytic activity of peritoneal macrophages was determined by the method based on the intensity of their capture ink particles. We studied the functional activity of peritoneal macrophages by NBT test (spontaneous and stimulated). Studies were conducted on male mice Category 1 (conventional linear mouse) line CBA/CaLac aged 2–2.5 months, weighing 20–22 g. After the introduction mice line CBA/CaLac of polyphenolic compounds derived from flowers of Carthamus tinctorius and flowers of Calendula officinalis L. during the 5-day course in dose 50 mg/kg was observed stimulation of the humoral immune response (total number of splenocytes, the number of antibodies in the spleen cells) and the functional activity of macrophages and Immunomodulating effect on the humoral immunity and the functional activity of macrophages after a single injection of cyclophosphamide in dose 250 mg/kg. Immunotropic activity of polyphenolic compounds is higher than that those of the reference product of tincture of Echinacea purpurea.
The influence of Sorbus sibirica, Calendula officinalis and Althaea officinalis extracts on the humoral immune response and nonspecific resistance of mice to immunosuppression by cyclophosphan was studied. It was shown that these extracts are not inferior to Echinacea purpurea tincture in terms of stimulation of humoral immune response, phagocytic and bactericidal activity of peritoneal macrophages but exceed effect of E. purpurea on phagocytic activity of peripheral blood neutrophils.
