The active ingredients in the Elderflower liquid extract are responsible for the antibacterial, antioxidant and anti-inflammatory effects of the plant. The aim of the study was to design semisolid formulations with liquid Elderflower extract and evaluate the quality of them using a biopharmaceutical research method in vitro. The quality of the Elderflower (Sambucus nigra L.) extracts were evaluated spectrophotometrically by determining the total polyphenols and flavonoids content. Antiradical activity was determined by employing the spectrophotometrically DPPH free radical scavening method. Antibacterial activity was determined in vitro using the agar diffusion method. The biopharmaceutical experiment in vitro of the semisolid pharmaceutical formulations was performed by using modified Franz type diffusion cells. The results revealed that the highest amount of active compounds were found in the extracts when 70% (v/v) ethanol was used for the extraction of the raw material. The extracts obtained have antiradical activity and antimicrobial effects against S. aureus and B. cereus. Released amount of active compounds decreased when oleogel concentration in the formulation increased. The in vitro results of a biopharmaceutical semisolid formulation study showed that the base and the amount of excipients affected the release kinetics of the active compounds from the formulations. The results of the study showed that, as the lipophilicity and viscosity of the base increase, the formulation is characterized by a prolonged action: the release of the flavonoids, with the increase in the amount of oleogel, slow down. The best carrier of ederflower liquid extract was confirmed the hydrophilic base.

Background. Osmolalities can be useful markers for determining whether given beverages are suited for maintaining an adequate hydration of the body. Losing 2% of body water relative to body mass reduces the efficiency of body function when undertaking physical effort by around 20%. Deficiencies in water intakes approaching 5-8% of body mass, double the impairment to the body’s physical and mental functioning, whereas at a level of 10% the body becomes incapable of performing any sort of physical effort. For such reasons the body’s hydration status is vital to its functioning. Objectives. To asses osmolalities as measured in various types of commercially available mineral waters and non-alcoholic beverages containing different amounts of extracts. Materials and Methods. Test materials were commercially available mineral waters (of low, medium and high mineral content) along with juices, nectars and drinks that are isotonic, energising and those described as being ‘light’ and sparkling. Osmolality was measured by the 800CL Osmometer instrument from TridentMed whilst the RL-type refractometer was used for determining extract values. Results. Isotonic drinks were found to have the same osmotic pressures as bodily fluids at 275 – 295 mOsm/kg water. The osmotic pressure in mineral waters depended on the extent of mineralisation and ranged from 13 mOsm / kg water (low mineral content) to 119 mOsm/kg water (high mineral content). Low osmolalities were also found in ‘light’ drinks (from 29.3 to 34 mOsm/kg water). Juices, nectars, energising drinks and colas typically have high sugar contents and have high osmolalities ranging 492 – 784 mOsm / kg water. Statistical analysis demonstrated significant associations (p < 0.05) between osmolalities and extract content in beverages as well as between osmolalities and mineral content in mineral waters. Upon factor analysis, it was possible to group the tested drinks according to similar osmolalities and extract content. Conclusions. Osmolalities measured in beverages are a marker that permits drinks to be classified into groups according to their tonicity and their ability to ensure that the body is properly hydrated; this becoming vital in cases when the body requires rapid body fluid replenishment.

Wprowadzenie. Wartość osmolalności napojów może być wykorzystana jako wskaźnik ich przydatności do właściwego nawadniania organizmu. Utrata wody w wysokości 2% w stosunku do masy ciała obniża wydolność fizyczną o około 20%. Niedobór wody sięgający 5-8% masy ciała powoduje dalsze zaburzenia wydolności fizycznej i psychicznej, a przy stracie wody do 10% masy ciała człowiek jest niezdolny do wykonywania jakiegokolwiek wysiłku fizycznego. Dlatego też kontrola stanu nawodnienia organizmu jest bardzo istotna. Cel. Celem badań była ocena zmierzonej osmolalności różnych wód mineralnych (nisko, średnio i wysoko zmineralizowanych) oraz soków, nektarów, napojów izotonicznych, energetyzujących, „light” i gazowanych zawierających różne zawartości ekstraktu ogółem (oBx). Materiał i metody. Materiał do badań stanowiły komercyjnie dostępne wody mineralne (nisko, średnio i wysoko zmineralizowane) oraz soki, nektary, napoje izotoniczne, energetyzujące i „light” oraz gazowane o różnej zawartości ekstraktu. Osmolalność oznaczono przy wykorzystaniu osmometru 800 CL firmy Trident Med., natomiast zawartość cukrów mierzono refraktometrem typu RL. Wyniki poddano analizie statystycznej wykorzystując program Statistica v. 12. Wyniki. Stwierdzono, że napoje izotoniczne charakteryzowały się typowym dla płynów ustrojowych ciśnieniem osmolalnym (275-295 mOsm/kg H2O). Ciśnienie osmolalne wód mineralnych zależało od stopnia ich mineralizacji i wahało się od 13 mOsm/kg H2O (nisko zmineralizowane) do 119 mOsm/kg H2O (wysoko zmineralizowane). Niską osmolalność wykazywały także napoje typu „light” (od 29,3 do 34 mOsm/kg H2O). Soki, nektary, napoje energetyzujące oraz napoje typu „cola” charakteryzujące się wysokim udziałem cukrów wykazywały wysoką osmolalność wynoszącą od 492 do 784 mOsm/kg H2O. Analiza statystyczna wyników wykazała, że istnieje istotna zależność (p < 0,05) pomiędzy osmolalnością a zawartością ekstraktu ogółem w napojach, a w wodach mineralnych pomiędzy osmolalnością a zawartością składników mineralnych. Analiza czynnikowa pozwoliła na pogrupowanie badanych napojów produkowanych przemysłowo wg podobnej osmolalności i zawartości ekstraktu ogółem na grupy o podobnej osmolalności i zawartości ekstraktu ogółem. Wnioski.. Osmolalności zmierzone w napojach są markerami, które pozwalają klasyfikować napoje według grup w zależności od ich toniczności i ich zdolności do zapewnienia, że organizm jest odpowiednio nawodniony. Staje się to niezbędne w przypadkach, gdy organizm wymaga szybkiego uzupełnienia płynu ustrojowego.

Three low coalified coal samples of Upper- Vistula Coal Basin (Poland) were object of geochemical analysis by pyrolitic, chromatographic and spectrographic methods. Coal extracts and low-temperature tars received in three temperatures: 390, 520 and 600°C in the presence of n-butanol-l vapour were separated into three fractions: aliphatic, aromatic and polar (NSO compounds + asphaltenes) using preparative TLC for gross composition assessment. Infrared spectroscopy of overall primary tars indicates that lower coalified coals give primary tars containing much higher amounts of oxygen 'compounds then higher coalified coals and that with increase of pyrolysis temperature the content of aliphatic structures in tars tends to decrease. Aliphatic compound fractions were analysed by gas chromatography to assess changes in n-alkanes, n-alkenes and isoprenoid compounds distribution and changes of main biomarker parameters with changes of pyrolysis temperature comparing to coal extracts. Results of gc analysis indicated similar thermal maturity of coals and their various depositional environment ( oxic in the case of the Czeczott and J anina coals and anoxic-suboxic for the Siersza coal). In lower temperatures of pyrolysis (390°C) high predominance of even-carbon-number n-alkanes and n-alk-l-enes was found caused by generation even-carbon-number aliphatic compounds from coal macromolecule. As a probable source of pristane in coals vitrinite macerals were supposed.

Palm (Phoenix dactylifera L.) is a specie cultivated in Mauritania. The present study is focused on the potential of the aqueous extract of the Pergularia tomentosa L., as biological control agent against Fusarium brachygibbosum, the main agent of the date palm stipe rot disease in Mauritania. Fungal pathogen was isolated from symptomatic date palm stipe rot disease in Mauritania. The morphological characterization and the molecular identification by sequencing ITS1, ITS2 5.8 RNAr region showed homology of 98% with Fusarium brachygibbosum strain UOA/HCPF 16982 s during in vitro tests on leaves performed to verify its phytopathogenicity. The inhibitory effect of aqueous extract of Pergularia tomentosa L. on the phytopathogenic isolate (Fusarium brachygibbosum) of date palm, on mycelial growth and spore germination was observed. In fact, in vitro on PDA, mycelial growth ranged from 39.23 to 67.7%, depending on the concentration of the aqueous extract of P. tomentosa. The aqueous extract showed a reduction of spore germination varying from 5.3 to 23.8%. The minimum inhibitory concentrations varied from 1 to 100 mg/ml. The various extracts give high antioxidant activities exhibited by DPPH assay. Multivariant analysis by PCA plot and the heatmap were done, to evaluate the correlation between the tested parameters. These results suggest the use of Pergularia tomentosa L., extract as a biological agent to control and reduce damage caused by Fusarium brachygibbosum.

In recent years, many studies have been focused on natural substances that can affect health of animals. A mix of different extracts was used as dietary supplement and it consists exclusively of natural products. Its main components are polyphenols from terrestrial and marine origins and plant polysaccharides. The effect of this supplement on reproduction has not been reviewed in the past what is a reason why its effect on the reproduction potential of male rabbits was tested. The aim of the present study is to determine effects of natural mix during 120-days long in vivo experiment on selected reproductive traits of male rabbits. Natural mix was supplemented in two different concentrations (T1 – 0.3% and T2 – 0.6%) with the basal ingredients of the conventional rabbit feed in pellet form. In our experiments, emphasis was placed on both the spermatozoa concentration and its motility parameters as well as on the properties of seminal plasma and antioxidant activity. The dietary supplementation with the natural extracts mix positively altered the quality traits of rabbit spermatozoa, but these changes were statistically not significant. In experimental T1 group a significant increase of GPx and FRAP content, both regarding the antioxidant markers profile in seminal plasma was recorded. We can conclude that the supplementation of 0.3% of natural mix did not significantly negatively affect any of the studied reproductive parameters of male rabbits, but some improvement in several antioxidant parameters was found.
