    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.

    Opis:
    The research goals of presented work consisted of determination of zinc and indole compounds that are released into artificial digestive juices from Tricholoma equestre species. During the experiment freeze-dried samples of wild growing fruiting bodies and mycelia from in vitro cultures from liquid Oddoux medium were extracted to artificial digestive juices (saliva, gastric juice and intestinal juice). In the next step the determination of examined compounds was done by RP-HPLC for indole compounds and DP ASV for zinc. Furthermore it was decided to check weather this species has any beneficial properties for health. The extraction of researched material in conditions imitating human digestive tract allows determination of true amounts of elements released to artificial digestive juices and their beneficial influence (a specially designed and constructed apparatus Gastroel-2014 was applied). The indole compound with the highest quantity was 5-hydroxy-L-tryptophan, both in fruiting bodies and in biomass from in vitro cultures of T. equestre (up to 352.47 mg/100 g d.w.). Serotonin and L-tryptophan was determined in all analysed samples, but their amounts were significantly lower than the ones found for 5-hydroxy-L-tryptophan. The amounts of zinc on the other hand showed that the biggest concentration of zinc can be obtained for fruiting bodies and biomass from in vitro cultures to both artificial saliva and gastric juice after 120 minutes of digestion (6.83 14.4 mg/100 g d.w. retrospectively) in conditions that imitate human digestive track.

    Opis:
    Lecznicze i przeciwutleniające właściwości grzybów są doskonałym połączeniem, które stanowi o ich wartości dietetycznej i umożliwia korzystanie z nich zarówno, jako żywności jak i dodatku żywieniowego. Celem niniejszej pracy była analiza zawartości fizjologicznie aktywnych związków indolowych w mycelium z kultur in vitro Agaricus bisporus (pieczarka dwuzarodnikowa). L-tryptofan, egzogenny aminokwas i jego pochodne, takie jak np. 5-hydroksytryptofan, muszą być dostarczane z pokarmem w codziennej diecie. Związki te mają działanie przeciwdepresyjne, są bezpośrednimi prekursorami serotoniny, a w przeciwieństwie do niej przekraczają barierę krew – mózg. Są też biogenetycznymi prekursorami innych związków indolowych, które pełnią funkcję neuroprzekaźników, co uzasadnia oznaczanie ich zawartości w grzybach jadalnych. Materiał do badań stanowiły owocniki A. bisporus pochodzenia komercyjnego. Z owocników A. bisporus wyprowadzono kultury in vitro na podłożu stałym Oddoux (1957). Eksperymentalne kultury in vitro prowadzono na płynnym, wytrząsanym podłożu Oddoux. Co dwa tygodnie prowadzenia kultur pasażowano je na świeżą pożywkę. Biomasę mrożono i suszono metodą liofilizacji. Otrzymaną biomasę z kultur in vitro analizowano jakościowo i ilościowo metodą HPLC na obecność niehalucynogennych związków indolowych. Po raz pierwszy zidentyfikowane i ilościowo oznaczone zostały związki indolowe w kulturach in vitro Agaricus bisporus na płynnym podłożu wg Oddoux. Analiza wykazała, że ekstrakty metanolowe otrzymane z grzybni zawierają sześć związków indolowych: L -tryptofan, 5 - hydroksytryptofan, serotoninę, melatoninę, tryptaminę i 5-metylotryptamię. Zawartości poszczególnych składników w biomasie z kultur in vitro były zróżnicowane w zakresie od 0,01 do 21,33 mg/100 g s. m. Dominującymi ilościowo związkami były: 5-hydroksytryptofan (12,50 mg/100 g s. m.), L-tryptofan (14,00 mg/100 g) i serotonina (7,00 mg/100 g). Całkowita zawartość związków indolowych w badanym materiale wynosiła 55,32 mg/100 g s. m. Biomasa z kultur in vitro badanego gatunku jest dobrym źródłem 5-hydroksytryptofanu i L- tryptofanu. Kultury in vitro A. bisporus mogą być wykorzystane jako model do badań nad akumulacją i metabolizmem związków indolowych.
    Methanolic extracts obtained from biomass of Agaricus bisporus (J.E. Lange) Imbach cultured in vitro were analyzed for qualitative and quantitative composition of non-hallucinogenic indole compounds in order to compare their amount with fruiting bodies of these species. Extracts demonstrated to contain six indole compounds. Contents of individual compounds ranged from 0.01 to 21.33 mg/100 g d.w. in biomass from in vitro cultures. The quantitatively dominating compounds included: 5-hydroxytryptophan (12.50 mg/100 g d.w.), L-tryptophan (14.00 mg/100 g d.w.) and serotonin (7.00 mg/100 g d.w.). Total content of the remaining indole compounds under analysis in the study was 55.32 mg/100 g d.w.

    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:
    Due to the valuable properties of carotenoidsthe interest in new methods of obtaining them is still increasing. For this purpose, since the 60s of the twentieth century, scientists conducted numerous studies to recognize the processes in which carotenoids could be produced . Carotenoids, revealing a strong antioxidant activity, act as free radical scavengers. These compounds can support many beneficial processes such as the stimulation of the immune system, the modulation of intracellular signaling pathways, the regulation of the cell cycle and apoptosis as well as theregulation of growth factors. Carotenoids were determined by spectrophotometric analysis in the following fungal species: Leucopaxillus giganteus, Sarcodon imbricatus, Lactarius piperatus, Lactarius deliciosus, Agaricus arvensis, Agaricus bisporus, Agaricus romagnesii, Agaricus silvaticus, Agaricus silvicola, Hypholoma fasciculare, Calocybe gambosa, Craterellus cornucopioides, Marasmius oreades. High performance liquid chromatography (HPLC) coupled with a UV detector detected β,β-carotene in Agaricus bisporus, Polyporus squamosus, Lepista nuda, Russula delica, Verpa conica, Pleurotus ostreatus and Hypsizgus marmoreus. β-carotene and lycopene were also found in three wild species of edible mushrooms: Leucopaxillus giganteus, Sarcodon imbricatus and Agaricus arvensi. These compounds were isolated in several species of the family Cantharellus as well. One example is Cantharellus cibarius, which contains mainly β,β-carotene and minor amounts of lycopene, α-carotene and other carotenoids, which may be δ – and γ – isomers.

    Opis:
    Lentinula edodes (Berk.) Pegler (shiitake) is a species with medicinal properties that is used primarily in traditional medicine, but also in conventional oncology treatment. The first records of Lentinula edodes cultivation reach back to China under the Song dynast (960-1127). The Japanese adopted the Chinese technique of shiitake cultivation, thus becoming its main producer. Currently, shiitake is used in the treatment of lifestyle diseases. Polysaccharides contained in this species strengthen the immune system, eliminate side effects of chemo and radiotherapy and have strong antitumor, antiviral and antibacterial properties. The year 1972 saw a discovery of substances with anti-atherosclerotic effects, with the most important being eritadenine (2 (R), 3 (R)-dihydroxy-4 – (9-adanyl) butyric acid) and statin – lovastatin. L. edodes is of interest to researchers due to its content of therapeutic compounds. These substances have antitumor, antifungal, antibacterial, anti-inflammatory, hypocholesterolemic, antihypertensive, hypoglycaemic and antioxidant effects.

    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.

    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:
    Species of the genus Ganoderma are an example of some of the most thoroughly studied representatives of Basidiomycota both in terms of chemical composition and biological activity. Among the compounds found in this kind, the therapeutic effect is primarily associated with the polysaccharides that are heteroglycans or β-D-glucans and terpenoids represented mainly by triterpenes. Triterpene compounds have a structure composed of 30 carbon atoms, usually forming a system of five six-membered rings. Characteristic of these structures are functional groups (hydroxyl, carboxyl or ketone) and double bonds. Mycochemical studies have led to the isolation of numerous triterpenes of the lanostane type (ganoderic acids, aldehydes, alcohols, esters), lucidenic acids and others from various species of the Ganoderma genus. The broad spectrum of biological activity determined by triterpene compounds includes anti- tumor, anti-inflammatory, antioxidant, hepatoprotective, antidiabetic, and antiviral effects. This work describes biologically active triterpenes in selected species of the genus Ganoderma: Ganoderma lucidum, Ganoderma applanatum, Ganoderma adspersum, Ganoderma pfeifferi, Ganoderma colossum and others. These species are sources of natural compounds valued for thousands of years in the traditional medicine of the Far East, while ongoing research has confirmed their medicinal properties nowadays.

    Opis:
    A group of natural sterols isolated from mushrooms are mycosterols, of which derivatives the most interesting is ergosterol (5,7,22-ergostatrien-3β-ol) and its peroxide, which are presented in the fruiting bodies of most of the representatives of the Basidiomycota taxon. Mushroom sterols are synthesized in a similar way, but the reaction sequence, which is squalene metabolism and the stereochemistry of the major products are different. As with many derivatives of isoprene, the basic unit of the synthesis of sterols is isopentenyl pyrophosphate (IPP), which in turn is synthesized from acetyl-CoA by alternately pass away of mevalonic acid. Mycosteroles, they are considered beneficial compounds that have health promoting effects. It has been proven their ability to lower serum cholesterol, may also be effective in the prevention of certain types of cancer. Ergosterol, which is common in mushrooms, as peroxidation products thereof, also exhibits many beneficial effects. It may have the potential health benefits and influence on the improvement of essential physiological functions of human body, including reduced pain associated with the activity of inflammation, reduction in the incidence of cardiovascular disease, inhibition of the enzyme cyclooxygenase (COX) and lowering cholesterol levels. It also has antioxidant properties and inhibit the growth of fungi and bacteria.

    Opis:
    Humans have used mushrooms from the beginning of their history. However, during the last few decades, the market demand for these fruiting bodies has increased significantly owing to the spread in the capabilities of culinary and pharmacological exploitation. Natural mushroom resources have become insufficient to meet the support needs. Therefore, traditional methods of extensive cultivation as well as modern technologies have been exploited to develop effective growing recommendations for dozens of economically important mushroom species. Mushrooms can decompose a wide range of organic materials, including organic waste. They play a fundamental role in nutrient cycling and exchange in the environment. The challenge is a proper substrate composition, including bio-fortified essential elements, and the application of growing conditions to enable a continuous supply of fruiting bodies of market quality and stabilized chemical composition. Many mushroom species are used for food preparation. Moreover, they are treated as functional foods, because they have health benefits beyond their nutritional value, and are used as natural medicines in many countries. Owing to the rapid development of mushroom farming, we reviewed the growing technologies used worldwide for mushroom species developed for food, processing, and pharmacological industries.
