Monascus species have been known to produce at least six
molecular structures of pigments, which are classified into three
groups based on their colors, i.e., yellow pigments (monascin
(R = C5H11) and ankaflavin (R = C7H15)), orange pigments (monascorubrin
(R = C5H11) and rubropunctatin (R = C7H15)) (Fig. 1), as
well as red pigments (monascorubramine and rubropuntamine)
