Opis:
Grzyby z gromady Basidiomycota od dawna budzą zainteresowanie ze względu na występowanie w ich owocnikach szeregu związków o uznanych właściwościach leczniczych. Obiektem przeprowadzonych badań były kultury mycelialne dwóch gatunków grzybów afylloforoidalnych występujących na terenie Polski Hydnum repandum L. oraz Sparassis crispa (Wulf.) Fr. Celem podjętych badań była jakościowa i ilościowa analiza ekstraktów otrzymanych z kultur mycelialnych pod kątem występowania związków o udokumentowanej aktywności biologicznej: kwasów fenolowych, niehalucynogennych związków indolowych oraz steroli. Do oznaczeń wykorzystano wysokosprawną chromatografię cieczową faz odwróconych (RP-HPLC). Na podstawie analizy stwierdzono w ekstraktach z otrzymanej biomasy obecność ośmiu kwasów fenolowych: galusowego, gentyzynowego, p-hydroksybenzoesowego, kawowego, kumarowego, protokatechowego, syryngowego, wanilinowego oraz kwasu cynamonowego. Ilościowo dominującym związkiem był kwas protokatechowy w ilości 6,23 μg/g s.m. (H. repandum) oraz kwas hydroksybenzoesowy w ilości 4,52 μg/g s.m. (S. crispa). Spośród związków pochodnych indolu ilościowo oznaczono: indol, serotoninę, tryptaminę i tryptofan. Całkowita ich zawartość wynosiła 1,28 μg/g s. m. (ekstrakty z H. repandum) oraz 3,07 μg/g s.m. (ekstrakty z S.crispa). Ilościowo dominującym metabolitem był tryptofan. Spośród steroli oznaczono ergosterol w biomasie z kultur in vitro S. crispa (700,87 μg/g s.m). Uzyskane wyniki wskazują, że przebadane kultury mycelialne krajowych gatunków grzybów afylloforoidalnych są zdolne do akumulacji metabolitów aktywnych biologicznie.  
For a long time fungi belonging to Basidiomycota phylum have been in the center of attention because of the presence in their fruiting bodies of compounds with known therapeutic activity. Mycelial cultures of two aphyllophorales species occurring in Poland, Hydnum repandum L., and Sparassis crispa (Wulf.) Fr., were analyzed in our study. The main aim of the study was qualitative and quantitative analysis of extracts obtained from the mycelial cultures for the presence of known biologically active compounds, including phenolic acids, non-hallucinogenic indole compounds and sterols. For analyses a reversed-phase chromatography (RP-HPLC) method was used. The presence of eight phenolic acids including gallic, gentisic, p-hydroxybenzoic, caffeic, p-coumaric protocatechuic, syringic, vanillic and cinnamic acids was confirmed in the extracts obtained from the biomass. The quantitatively predominant metabolites in biomass from in vitro cultures of H. repandum and S. crispa were protocatechuic acid (6.23 μg/g DW) and p-hydroxybenzoic acid (4.52 μg/g DW). Derivatives of indole such as indole, serotonin, tryptamine and tryptophan were measured quantitatively. Their total content was estimated as 1.28 μg/g DW and 3.07 μg/g DW in H. repandum and S. crispa extracts, respectively. The major metabolite found was tryptophan. In addition, ergosterol, one of the sterols present in the biomass of in vitro cultures of S. crispa was analyzed (700.87 μg/g DW). The obtained results confirm the hypothesis that mycelial cultures of domestic species of aphyllophorales are able to accumulate biologically active metabolites.

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:
Bacopa monnieri (Scrophulariaceae) is a well-known plant and has been used by humans for several thousand years. In traditional Hindu medicine, it is one of the most important medicinal plants. The aim of the work was to determine the content of Fe, Mg, and Zn and selected organic compounds before and after extraction into the artificial digestive juices obtained from preparations containing B. monnieri. Commercial preparations in the form of tablets and capsules and B. monnieri shoot cultures were used in the experiment. The metal content in the considered mineralized samples was analyzed by atomic absorption spectrometry and organic compounds by RP-HPLC method. The maximum measured content of the metals released into the digestive juices was as follows: Fe – 32.85; Mg – 367.51; and Zn – 16.41 mg/100 g of the preparation. The existing research shows that metals are best released into the artificial digestive juices from the B. monnieri shoot cultures, and least efficiently from the commercial preparations available in the form of tablets. The phenolic compounds analyzed in the methanol extracts and the extracts of the artificial digestive juices were as follows: protocatechuic acid, p-hydroxybenzoic acid, neochlorogenic acid, chlorogenic acid, isochlorogenic acid, caffeic acid, ferulic acid, cynaroside, trifolin, and luteolin. Bacoside A was only determined in the extracts from the B. monnieri shoot cultures. The experimental results revealed that B. monnieri distributed in the form of tablets did not break down in the artificial digestive juices during the considered time intervals.

Opis:
Arthrospira platensis (Spirulina platensis) is a well-known microalga and has been utilized as a medicinal agent and foodstuff by humans since at least 16th century. The aim of this study was to determine zinc content as well as determine phenolic and indole compounds from commercial preparations containing Arthrospira platensis (lyophilizate, tablets, and capsules) before and after extraction with methanol and incubation with artificial digestive juices. The secondary aim of this study was to evaluate the quality of these preparations. The samples were incubated in artificial stomach juice and in intestinal juice. The samples were mineralized and their zinc(II) ions content was estimated using flame absorption atomic spectroscopy (F-AAS). The maximum zinc(II) ions content released into the digestive juices was found to be up to 1.6 mg 100 g-1 of the preparation. Phenolic compounds identified in the examined extracts are as follows: gallic acid; protocatechuic acid; 3,4-dihydroxyphenylacetic acid; p-hydroxybenzoic acid; syringe acid; cinnamic acid; and quercetin. Furthermore, indole compounds identified were 5-hydroxy-L-tryptophan, 5-methyl-L-tryptophan, L-tryptophan, tryptamine, and 5-methyltryptamine. Consequently, it was also found that the distributed Arthrospira platensis in the form of tablets does not disintegrate in the artificial digestive juices. Among the examined preparations, only hard capsules met the requirements of the European Pharmacopeia 8th ed.

Opis:
The purpose of this study was to analyze the indolic, phenolic, and fatty acid content and antioxidant activity of garlic sprouts growing in the dark and in the daylight. The pro- or anti-inflammatory properties of the garlic sprout extract were investigated by evaluating the cyclooxygenase-2 (COX-2), prostaglandin E synthase (cPGES), glutathione S transferase (GSTM1), nuclear factor NF-κB, peroxisome proliferator-activated receptors (PPARs), and aryl hydrocarbon receptor (AhR) protein levels in the RAW 264.7 cells activated with lipopolysaccharide (LPS). The highest amount of total indolic (73.56 mg/100 g f.w.) and phenolic compounds (36.23 mg/100 g f.w.) was detected in garlic sprouts grown in the daylight. Studies on antioxidant activity (the FRAP and DPPH method) of garlic sprouts showed that this activity is significantly higher for sprouts grown in full access to light when compared to those grown in the dark. In garlic sprout extracts, α-linolenic acid (ALA) was found to be in greater amount. COX-2 and cPGES level was lower when compared to LPS alone activated cells. After garlic extract treatment, higher level of GSTM1, PPARΥ, cytosolic p50 and p65 protein, as well as a lower NF-ĸB p50/p65 activity was noted in the RAW 264.7 cells which suggested PPARs and AhR transrepression mechanism of NF-ĸB signalling. The obtained results indicate Allium sativum sprouts are a rich source of n-3 fatty acids, indolic and phenolic compounds characterized by anti-inflammatory and antioxidative activity, which may support their high therapeutic and dietary potential.
