Substances with antitumor activity isolated from Sepedonium ampullosporum, Cercospora oryzae and Coriolus unicolor were chemically and spectrometrically studied. They were identified as the mixtures of 1-monoglycerides, having octadecenoic and octadecadienoic acids with or without hexadecanoic acid as the main components. They contain other fatty acids with larger and smaller carbon numbers as the minor components. Fatty acid composition of the monoglycerides depends upon the origin of the glycerides.
