title: Neogrifolin derivatives possessing anti-oxidative activity from the mushroom Albatrellus ovinus.
abstract: Three neogrifolin derivatives, 3-hydroxyneogrifolin, 1-formylneogrifolin and 1-formyl-3-hydroxyneogrifolin along with grifolin and neogrifolin were isolated from the Japanese mushroom Albatrellus ovinus belonging to Scutigeraceae. Their structures were established by a combination of two-dimensional NMR spectroscopic analyses and by chemical synthesis. 3-Hydroxyneogrifolin and 1-formyl-3-hydroxy-neogrifolin showed more potent antioxidative activity properties than either alpha-tocopherol or BHA.
