Abstract A monascus red pigment (resolved in water) was radiated with UV-light until it became colorless, the molecular formulas of the colorlessness were determined by MS and H1NMR, they were C31H45NO10、C15H24O5、C16H21NO5. The photobleaching mechanism of the red pigment was deduced according to photochemical theory.
