“…Similarly, the influence of other cultivation parameters (casing soil, flush number, developmental stage and tissue distribution) in their sterols content was also determined. The total fungal sterols content of A. bisporus mushrooms using the modified extraction method ranged from 3.1-11.2 mg/g dw thus results were in concordance with previous reports (Teichmann, Dutta, Staffas, & Jagerstad, 2007;Mattila, Lampi, Ronkainen, Toivo, & Piironen, 2007) Firstly, the fungal sterols content was measured in the fruiting bodies harvested from substrates inoculated with different spawn varieties ( Table 1). Two of the Agaricus bisporus strains (Fungisem H15 and Mispaj 365) showed significantly higher ergosterol levels than the others although the levels of the minor sterols were similar.…”

“…According to the GC-MS database, the identified the peaks were in concordance with previous studies (Teichmann, Dutta, Staffas, & Jagerstad, 2007;Jasinghe & Perera, 2005). The detected sterols were ergosterol (ergosta-5,7,22-trien-3β-ol) as the major sterol (RT= 13.3 min) being 83% of the total sterols content followed by ergosta 7,22-dienol (RT= 13.6 min), ergosta-5,7-dienol (RT= 14.0 min) and ergosta-7-enol (fungisterol) (RT= 14.3 min).…”

“…Ergosterol (ergosta-5,7,22-trien-3β-ol) is the major sterol of their hyphae membranes (approx. 80% of the sterols w/w) followed by other 4 derivatives such as ergosta-5,8,22-trien-3-ol, ergosta-7,22-dien-3-ol, ergosta-5,7-dien-3-ol and ergosta-7-en-3-ol (fungisterol) Their presence and concentration is specie dependent influenced by many other environmental factors (Yokokawa & Mitsuhashi, 1981;Teichmann, Dutta, Staffas, & Jagerstad, 2007;Mattila, Lampi, Ronkainen, Toivo, & Piironen, 2007;Kalač, 2009;Senatore, Dini, Marino & Schettino, 1988).…”

Ergosterol, ergosta7,22 dienol, ergosta 5,7 dienol, fungisterol,7,6,8(14),22-tetraen-3-ona were the fungal sterols detected in Agaricus bisporus mushrooms after optimization of an sterol extraction method. Their concentration ranged from 3.1-11.2 mg/g dw depending on the strain, casing soil, flush number, developmental stage and sporophore tissue analyzed. Two methods were optimized to obtain sterols enriched extracts from A. bisporus fruiting bodies using pressurized fluid (PLE) and supercritical fluid extractions (SFE). PLE using ethanol as solvent at 10.7 MPa (50ºC and 100ºC) after 5 cycles of 5 min extraction (mixing in the extraction cell the sample with sand in a ratio 1:4) yielded extracts with respect. 5 and 2.9% sterols. Using SFE-CO2 at 40ºC and 9 to 30 MPa fractions containing 60% of sterols were obtained. Both technologies could be also utilized to extract sterols from mushroom by-products (the lower part of the stipe) as a method for their valorization. IntroductionCardiovascular diseases (CVD) are one of the leading causes of death in industrialized countries. Although, up to 80% of the cases could be prevented by changing style life, advertises of public agencies do not have the impact they should.Nowadays, only the consumption of functional foods with hypocholesterolemic properties seems to be better accepted by the CVD risk population than other changes.The functional foods, available at the markets, bearing the claim `able to reduce cholesterol levels in serum´ contain mainly plant phytosterol (Ling & Jones, 1995;Turnham, 1999), or cereal β-glucans. The mechanism of action of the hypocholesterolemic β-glucans is not completely elucidated (Cheickna & Hui, 2012) while apparently the phytosterols are able to impair cholesterol absorption by displacing Edible mushrooms also contain sterols with structural similarities to phytosterols and cholesterol. Thus, these fungal molecules might also act as phytosterols displacing cholesterol from the DMMs. Ergosterol (ergosta-5,7,22-trien-3β-ol) is the major sterol of their hyphae membranes (approx. 80% of the sterols w/w) followed by other 4 derivatives such as ergosta-5,8,22-trien-3-ol, ergosta-7,22-dien-3-ol, ergosta-5,7-dien-3-ol and ergosta-7-en-3-ol In this work, ergosterol and derivatives were measured in several Agaricus bisporus varieties during different cultivation parameters, developmental stages, sporophore tissues etc. The sterols were extracted by both SFE and PLE technologies in order to compare them and define the optimal method and extraction parameters to obtain sterols-enriched fractions. Extractions were carried out using the complete fruiting body or the lower part of the stipe usually discarded as a by-product during harvesting to investigate the possible revalorization of this by-product as starting material to generate ergosterol-enriched fractions for novel functional ingredients with hypocholesterolemic properties. stage was studied). In some cases, the different sporophore tissues, including the lower part of the stipe...

“…Vitamin D2 may be synthetized in plants and mushrooms involving UV-B action on ergosterol (21). Cultivated mushrooms contain lower amounts of vitamin D2 than wildgrown, but if they are exposed to UV-B the amount of vitamin D2 increases (22). Dietary vitamin D is absorbed predominantly in the small intestine via chylomicrons which enter the lymphatic system that drains into the superior vena cava.…”

“…The pattern of the sterol profile shows that ergosterol is the main compound synthesized by wild growing and cultivated mushrooms [45,46]. Because of its antimicrobial, antitumor and anticomplementary activities, ergosterol and its peroxidation derivatives are currently under frequent investigation [47][48][49].…”
