An antitumor substance, Lampterol (C15H20O4) has been isolated from a japanese poisonous mushroom Lampteromyces japonicus (KAWAM.) SING., in an overall yield of 2×10-3% from the raw mushroom. The procedure is described in Chart 1. The activity of lampterol as measured against Ehrlich ascitic tumor in mice is 120γ/kg., and the toxicity as measured by intraperitoneal injection into normal mice is 5mg./kg. Lampterol gave a diacetate. Lampterol is isomerized to isolampterol when passed through an alumina column; isolampterol gave a triacetate.
