Amaranth seeds and their main product amaranth oil are a rich source of bioactive substances. The non-saponifi able substances which accompany lipids include: squalene, tocopherols, sterols and others. The aim of the study was to compare the content of squalene, tocopherols and phytosterols in amaranth oils obtained by various techniques. The oil was extracted from seeds (Amaranthus cruentus) with the use of supercritical fl uid extraction (SFE), extraction with a chloroform/methanol mixture and expeller pressing. Contents of squalene and tocopherols were determined with high performance liquid chromatography (HPLC) method. The content of sterols in oils was determined by gas chromatography coupled with mass spectrometry (GC-MS). The highest squalene content was found for the oil obtained as a result of supercritical CO2 extraction (6.95 g/100 g of oil). A lower content of squalene was noted in the oil extracted with organic solvents and in cold-pressed oil – 6.00 and 5.74 g/100 g of oil, respectively. The amaranth oils were characterised by a signifi cant content of tocopherols. The oil obtained as a result of fl uid extraction was characterised by the highest content of tocopherols (131.7 mg/100 g of oil). A dominating homologue (40%) was β-tocopherol. Also the same sample was characterised by the highest content of sterols (2.49 g/100 g of oil). In all samples the predominating sterol was sum of α-spinasterol and sitosterol, which accounted for 45%, 56% and 53% of total analysed sterols for the oil obtained from SFE, from extraction with solvents and from cold pressing, respectively.

In in vivo experiments the natural biologically active substances, which may reduce the application of chemical plant protection pesticides were examined. As dressing preparations water extracts (macerations, infusions) prepared from various parts of 39 plant species were used. For dressing non-disinfected seeds of two varieties of oat: Akt with naked seeds and Bajka with chaffed seeds were used. The experiment was conducted as a filter paper test, germination viability (I date) and germination capacity (II date) as well as healthiness of the seeds were determined. A significant differentiation of the effect of the extracts depending on extracts’ origin (plant), mode of their preparation and of interaction between these factors was revealed.

An oyster mushroom (Pleurotus ostreatus (Jacq.) P. Kumm) is a cultivated species of mushrooms characterizing with unique culinary and medicinal properties. Its’ nutritional value comes from proteins, carbohydrates, fatty acids, vitamins and mineral nutrients present in their fruitbodies. Because of a high content of fiber (mainly chitin) and low content of fat, they are a valuable element of an atherosclerosis diet. The fruitbodies of oyster mushrooms are an important source of biologically active substances, specific polysaccharides and polyphenols, which influence a human immune system, so that it fights against cancer cells. ß-D-glucans have an advantageous effect on digestive system, lower blood cholesterol and triglycerides level, decrease the risk of ischaemic heart disease. Active substances present in the mushrooms have antioxidant, antibacterial, antiviral, antidiabetic and anti-inflammatory properties. Numerous scientific studies prove high efficiency of the therapy with the use of preparations and extracts from Pleurotus ostreatus mycelia, both in prophylaxis and cure of civilization diseases, atherosclerosis and cancer.

Modern medicine, as well as the pharmaceutical, cosmetic and food industries appreciate the value of plant raw materials for their antiseptic, analgesic, anti-inflammatory and soothing effects. Medicinal plants, often found endemically, are often treated as potential sources of new substances with antimicrobial and antifungal activity. The aim of this study was to analyze the significance of selected medicinal and spice plants in terms of their ability to inhibit the growth of microorganisms, including those pathogenic to humans. The significance of active substances contained in selected plant species with high antimicrobial potential including Aloe vera L. and Chelidonium majus L. was described. The antimicrobial activity of plant oils, including those extracted from citrus and spice plants, was also analyzed. Plants are a rich source of many substances with a broad spectrum of activity. This knowledge has often been used in folk medicine, but it was not until the development of modern research methods that the mechanisms underlying the therapeutic properties of many plant substances and their proper use could be understood. New substances present in plant materials are constantly being discovered that may be of medical interest because of their great potential to be used against microorganisms or because of their antioxidant and anti-cancer properties.

Broad bean seeds, with a high nutritional value at green maturity stage, are used for direct human consumption and in food processing. However broad bean green seeds had as a very shortly time to use because the green seeds very quickly lost the white-green fresh colour. The aim of the study was to evaluate the content of biologically active substances in fresh broad bean seeds immediately after the harvest and seeds from pods stored for a week under low temperature conditions. Experimental material consisted of fresh, green broad bean seeds of Bachus, Basta, R-366/1, Bolero, Jankiel Biały, and Windsor Biały cultivars. Broad bean seeds were sown in the second decade of April at 60 × 10 cm spacing, 100 seeds per plot of 6.0 m2 area. Broad bean pods were harvested once at the stage of technological maturity of seeds in the second and third decade of July. Marketable seed samples of 500 g were collected for laboratory tests. At the same time, immediately after the harvest, samples of 2 kg marketable broad bean pods of each cultivar were collected and storage within 7 days at 1–4°C. The contents of L-ascorbic acid, chlorophyll (a + b), flavonoids (QE), free phenolic acids sum (CAE), and dry matter were determined in broad bean seeds directly after the harvest as well as in the seeds from the pods stored for 7 days. In the results of the investigation indicate that green faba bean seeds from the storage pods had a good white-green colour and marketable quality, however the seeds had the significantly lowest content of L-ascorbic acid and chlorophyll (a + b). The content of selected biologically active substances in the seeds after storage in the pods indicates a significant difference in dependence on cultivar.

W opracowaniach na temat ostropestu plamistego występuje szereg nieścisłości, które przede wszystkim dotyczą łacińskiej nazwy rośliny, składników sylimaryny, mylenia owoców z nasionami oraz używania określenia „bielmo”. W oparciu o naukową literaturę przedmiotu wskazano, że poprawną nazwą gatunkową jest Silybum marianum (L.) Gaertn., plonem ostropestu są owoce, a nasiona są bezbielmowe. Sylimaryna (kompleks flawonolignanów – sylibina, sylikrystyna i silidianina) skumulowana jest w owocni i łupinie nasiennej. W zależności od warunków wegetacji ostropest osiąga wysokość od około 0,7 do 1,7 m, a okres wegetacji na plantacjach surowcowych trwa 80-110 dni.

The present study investigated the chemical coding of neurons in the celiac-superior mesenteric ganglion complex supplying the normal (n = 4) and inflamed (n=4) ileum (chemically-in- duced inflammation) in juvenile pigs using retrograde tracing combined with immunohistochem- istry. Ileum-projecting neurons (IPN) were predominantly distributed in the left and right superior mesenteric pools of the ganglion. The majority of them were adrenergic (tyrosine hydroxylase-positive) and also contained neuropeptide Y, somatostatin or galanin. No clear-cut differences in the distribution and chemical coding of IPN were found between normal and inflamed pigs. However, in the inflamed group, the density of peptidergic, IPN-associated nerve fibres was higher than that found in the control group.
