Disposition of the waste sawdust substrate from sawdust-based cultivation of shiitake mushrooms (Lentinula edodes) is an important issue. In this study, we evaluated the physiol. activity in the water extracts of waste sawdust substrate which had been extracted, by the two-step hot/hot-compressed water percolation. The 180°C water extract of waste sawdust substrate contained some isoprenoid and high amounts of polyphenol. Addnl., high antioxidant activity was found in the 180°C water extract of the waste sawdust substrate in in vitro experiment (DPPH scavenging activity) and the human keratinocyte, HaCaT. This study suggested that the two-step hot/hot-compressed water percolation elutes the antioxidant components in the 180°C fraction from the waste sawdust substrate. In the experiment, the researchers used many compounds, for example, 2′,7′-Dichloro-3′,6′-dihydroxy-3H-spiro[isobenzofuran-1,9′-xanthen]-3-one (cas: 76-54-0Electric Literature of C20H10Cl2O5).
2′,7′-Dichloro-3′,6′-dihydroxy-3H-spiro[isobenzofuran-1,9′-xanthen]-3-one (cas: 76-54-0) belongs to benzofurans derivatives. Benzofuran is the “”parent”” of many related compounds with more complex structures. For example, psoralen is a benzofuran derivative that occurs in several plants. Substituted benzofurans find applications such as fluorescent sensors, oxidants, in drug discovery, and in another field of chemistry and agriculture.Electric Literature of C20H10Cl2O5
