Nowadays, one of the most important problems of clinical care is assisting the healing process in acute and chronic wounds of various origins. Current interest direction of drug therapy is the use of phytomedicines. African marigold is one of the most promising ones to obtain medicine for wound healing. According to literature data, extracts and individual compounds of marigold show antimicrobial, wound healing, antioxidant, anti-inflammatory and analgesic activity. Lipophilic extract of marigold is non-toxic and does not have local irritating and allergic effects. The aim of our research was to study the wound healing activity of the lipophilic extract obtained from the inflorescences of African marigold tall forms of the variety "Hawaii" (Tagetes erecta plena L. var. "Hawaii"). Materials and methods. The lipophilic extract was obtained from inflorescences of Tagetes erecta plena L. by extraction with corn deodorized oil in a ratio of 1:6. The resulting lipophilic extract was standardized for the content of carotenoids and flavonoids. The wound healing effect of the extract was determined based on the example of a simulated burn healing according to the time of perifocal reaction disappearance, skin sloughing, formation of granulation, initiation of marginal epithelialization and the end of healing. The number of animals with completely epithelialized wounds was determined on days 25 and 30 of the experiment. Results. The quantitative content of carotenoids (up to 80.51 ± 1.15 mg% equivalent to β-carotene) and flavonoids (up to 0.7120 ± 0.0060 % equivalent to patuletin) was determined by the lipophilic extract of Tagetes erecta plena L. var. «Hawaii» standardization. The duration of experimental wounds healing when applying the extract and reference preparation was up to 30.7 ± 1.4 days and 28.0 ± 1.8 days, respectively, which was significantly less than in the control group (up to 47.7 ± 4.0 days). Full epithelization of wounds was observed on day 25 of the experiment in 60 % of the animals receiving the extract, in 70 % of the animals receiving the reference preparation and only in 10 % of the animals which did not receive a treatment. On day 30 of the experiment, this indicator was 80, 90 and 30 %, respectively. The results of the experiment reliably testify to the fact that in animals treated with the studied lipophilic extract, the healing time of burn wounds was significantly less than in the untreated control group animals and practically did not differ from the healing time in animals treated with sea buckthorn oil. Conclusions. The lipophilic extract from inflorescences of Tageta erecta plena L. var. "Hawaii" has been studied for wound healing activity. The stages duration and the time of experimental wounds complete healing in animals receiving the studied extract and reference preparation were significantly reduced in comparison to the control group animals.
Key words: flavonoids, hydroxycinnamic acids, herb, achillea setacea Waldst. et Kit., a. submillefolium Klok. et Krytzka, HPLC. Plants of the genus achillea L. are rich in polyphenolic compounds, which play an important role in the prevention of chronic diseases, slowing down aging processes as well as reducing the risk of cardiovascular and neurodegenerative diseases. The most studied is the chemical composition of Achillea millefolium, while other plant species growing in Ukraine have not been studied enough. The aim of our work was researching the qualitative and quantitative composition of polyphenolic compounds in the herb of achillea setacea Waldst. et Kit. and a. submillefolium Klok. et Krytzka. Materials and methods. The shredded air-dry raw materials of Achillea submillefolium Klok. et Krytzka and A. setacea Waldst. et Kit. were used for the study. Thin-layer chromatography was used to identify flavonoids and hydroxycoric acids. The method of high-performance liquid chromatography was used to separate the sum of polyphenolic compounds into individual components. Results and discussion. Qualitative identification of flavonoids and hydroxycinnamic substances by TLC revealed the presence of chlorogenic and neochlorogenic acids, luteolin in both species, and rutin in a. setacea Waldst. et Kit. The content of hydroxycinnamic acids and flavonoid compounds were determined by HPLC method. The predominant components are luteolin-7,3’-di-O-β-D- glycoside, neochlorogenic acid, rutin, apigenin-7,4’-di-O- glucopyranoside. The obtained results make to predict the antioxidant, antibacterial and antifungal activity of the extracts of the studied plants.
A variety of drugs are widely used to treat fungal infections. Mostly they are products of chemical synthesis, but recently, due to the increased resistance of fungi to many synthetic drugs, the relevance of the use of herbal remedies in the complex treatment of both skin infections and deep mycoses has been increasing. The aim of our research was to study the chemical composition of the lyophilic extracts of Plantago media and Plantago altissima of the flora of Ukraine by HPLC and GLC-MS methods and also mycostatic activity of ethanol and lyophilic extracts of the studied plants. As a result of the research, aucubin iridoid was detected in the lyophilic extracts of both species. There were also detected 15 polyphenolic compounds among which prevails acteoside, plantamayoside, ferulic and chlorogenic acid. Alcohol and lyophilic extracts of P. media and P. altissima showed mycostatic activity to all studied strains of yeast, dermatophytic fungi and aspergillus. The mycostatic effect of alcoholic extracts of P. media and P. altissima was more evident in comparison with the mycostatic effect of lyophilic extracts. The most evident antifungal effect was presented by alcoholic extract of P. media in relation to the clinical strain of Aspergillus oryzae (18.0±1.0 mm), and alcoholic extract of P. altissima to the clinical strain of Malassezia sp. (18.0±0.5 mm). The data obtained indicate a wide range of mycostatic effects of Plantago media and Plantago altissima extracts and the prospectivity of these objects for practical use in medicine.
