Abstract: The polyenoyltetramic acid physarorubinic acid (2) has been isolated from microplasmodia of the slime mold Physarum polycephalum. The structure was elucidated by means of 1D- and 2D-NMR, IR, and UV spectroscopy and mass spectrometry. The stereochemistry was proven by synthesis of the tetramic acid unit and application of circular dichroism. It was shown that plasmodia of a white mutant strain also contain yellow pigments.
