    Opis:
    Phenolic compounds, both derivatives of benzoic and cinnammic acid, possess biologically valuable properties: anti-inflammatory, antioxidant, anticarcinogenic and others. Studies of the accumulation of these compounds focused mostly on plant material. Rich sources of these compounds are representatives of Basidiomycota taxon. The aim of the study was qualitative and quantitative HPLC analysis of phenolic acids in biomass from in vitro culture of selected edible mushroom species belonging to the phylum Basidiomycota: Agaricus bisporus, Boletus badius, Cantharellus cibarius. The investigations revealed the presence of the following acids: p-hydroxybenzoic, syringic and galic acid. Both the composition and the amount of phenolic acids in biomass of A. bisporus and Boletus badius were diverse. The total amount ranged from 6.07 mg·100 g−1 DW in A. bisporus to 14.78 mg·100 g−1 DW in Boletus badius. Syryngic acid amounts fluctuated in the range of 1.75–9.66 mg·100 g−1 DW, with its maximum in Boletus badius. Gallic acid dominated in the biomass of the same species (5.12 mg·100 g−1 DW). p-Hydroxybenzoic acid was found in biomass from in vitro culture of A. bisporus at levels 0.70 mg/100 g DW. In biomass of in vitro culture of Cantharellus cibarius no phenolic compounds were found before and after hydrolysis. The results of HPLC analyses show that in vitro culture of B. badius and A. bisporus are a good dietary source of phenolic compounds with antioxidant activity.

    Opis:
    In recent years an increase in the consumption of edible mushrooms has been observed. In many countries mushrooms have been a popular delicacy, as they add flavor and texture to a meal. Mushrooms are able to accumulate both primary and secondary metabolites. Some of them may play an antioxidant role, e.g. phenolic and indole compounds, flavonoids, terpenoids, sterols, ascorbic acid, ergothioneine and carotenoids and are a source of elements, e.g. selenium. Indole compounds fulfill the role of neurotransmitters or their precursors, exhibit antioxidant, anticancer, anti-inflammatory and anti-aging actions, regulate the diurnal cycle in humans and take part in blood coagulation. Biologically and therapeutically active metabolites of fungi are used to treat such serious diseases as cardiovascular diseases, diabetes, atherosclerosis and cancer. The intake of mushrooms clearly has a cholesterol-lowering effect or hypocholesterolemic effect by different mechanisms such as decreasing VLDL, improving lipid metabolism, inhibiting of activity of HMG-CoA reductase, and consequently preventing the development of atherosclerosis. The antioxidant and anti-inflammatory compounds occurring in mushrooms also may contribute to reduce the atherosclerosis risk.

    Opis:
    Bacopa monnieri (Water hyssop) is a hydrophyte occurring in Asia and the southern US states. This plant is known in India as Brahmi and has been used in Ayurvedic medicine for 5,000 years as sedative, supporting the treatment of insomnia and improving cerebral circulation. For the biological effect in this species are responsible triterpenoids saponins – bacosides. The aim of the study was to obtain the biomass of B. monnieri shoot in vitro cultures, and then evaluating the biomass growth and content of zinc. B. monnieri derived from in vitro culture on Murashige-Skoog medium (MS) and on the same medium, but enriched in organic additives and elements may be a good source of Zinc for the human body. The experiment was also conducted on the commercial formulations containing B. monnieri. For the determination of zinc ions DP ASV method was used. It was found that the use of highly mineralized water (mineral water “Stefan” – Spa Szczawnica) for extraction of B. monnieri biomass from in vitro culture provided the highest concentration of zinc in the material and for the biomass from MS medium with the addition of As (163.52, and 167.23 mg/mL, respectively). The lowest content was found in B. monnieri biomass from MS medium supplemented with serine, and the capsules product (13.54 and 14.57 mg/mL). For extracts of B. monnieri biomass from MS medium enriched with Zn salts into digestive juices the highest concentration of zinc was determined in gastric juice (6.88 mg/mL).
