Studies on pigments of the myxomycete Physarum nudum. I. Absorption spectra of the crude extracts of pigments from plasmodia cultured in continuous light and in darkness

L. Rakoczy


1. Method for extraction and crude separation of the plasmodial pigments of the myxomycete Physarum nudum cultured in light and in darkness were elaborated. 2. By the use of various solvents in the procedure of extraction three pigment fractions were obtained from plasmodia cultured in the dark and four fractions from those grown under continuous light. 3. The absorption spectra of the particular fractions within the UV and visible range were determined.
