Chromatographic profiles and antimicrobial activity of the essential oils obtained from some species and cultivars of the Mentheae tribe (Lamiaceae)
Abstract The present study was focused on the chemical composition and antimicrobial activity of the essential oils (EsO) obtained from five Lamiaceae representatives grown in the south of Ukraine. Among them are Salvia sclarea L., Monarda didyma (cultivar ‘Cambridge Scarlet’), Thymus pulegioides (cultivar ‘2/6-07’), Thymus vulgaris (cultivar ‘Jalos’), and Thymus serpyllum L. The component analysis of the EsO was carried out by gas chromatography method coupled with mass spectrometry (GC–MS). The antimicrobial properties of the EsO were determined using the agar diffusion test against widespread pathogenic bacterial strains (Staphylococcus aureus, Escherichia coli, Enterococcus faecalis, St…
Chronic kidney disease and dialysis therapy: incidence and prevalence in the world
Сhronic kidney disease (CKD) is the important public and medical problem in the world because of a large burden on health care systems. The prevalence of CKD and number of dialysis patients are increasing in the world. The prevalence and incidence of CKD depends on age, race, and gender of patients, region, and the presence of the CKD registry in a country. Diabetes mellitus (DM) and arterial hypertension (AH) are the most common causes of end stage renal disease (ESRD). It is projected that the number of dialysis patients will reach 5.5 million in 2030. Specific strategies and interventions should be urgently aimed at reducing in the burden of CKD by means of the prevention, detection and …
METHODICAL APPROACH TO THE DETERMINATION OF THE ANTIOXIDANT ACTIVITY OF THE ECHINACEA PURPUREA AND MONARDA FISTULOSA TINCTURES AS A QUALITY CRITERION OF THE DEVELOPMENT OF THEIR COMPOSITION AND LABORATORY TECHNOLOGY
Aim. The aim of the study was to develop the methodical approach to determine the antioxidant activity of the tinctures of Monarda fistulosa herb and flowers and roots of Echinacea purpurea, as well as to develop their technology in laboratory conditions.
 Materials and Methods. The following methods were used: analysis, synthesis, systematization, and comparison for processing of published scientific data on antioxidant activity; method for measuring the particle size of raw herbal materials; maceration and remaceration methods for obtaining the tested tinctures; DPPH test for the valuation of the antioxidant activity of the developed tinctures.
 Results and Discussion.
