CHEMICAL CONSTITUENTS OF ARMILLARIA MELLEA MYCELIUM Ⅶ. ISOLATION AND CHARACTERIZATION OF CHEMICAL CONSTITUENTS OF THE ACETONE EXTRACT

Eight compounds were isolated from the acetone extract of artificially cultutred mycelium of Armillaria mellea (Vahl. ex Fr.)Quel. (Tricholomataceae). Three of them are protoilludane sesquiterpenoid aromatic esters. Their structures were elucidated by spectral data analysis as the known 4′-methylmelledonal (Ⅰ)and two new compounds named armillaritin (Ⅱ) and armillarivin (Ⅲ). In addition, five known compounds were identified as D-erythritol, D-mannitol, azelaic acid, orsellinic acid and glycerin-α-monooleate.
