Abstract: Monacolin K (MK, also known as lovastatin), produced by fermenting steamed rice with Monascus sp.,is a beneficial secondary metabolite which has hypocholesterolemic effects. While some Monascus strains can produce the mycotoxin citrinin, which gives rise to a controversy over the safety of Monascus fermented products. In this study, 11 Monascuspurpureus and 10 Monascusruber strains were selected, and the contents of MK and citrinin in red yeast rice produced by these strains were analyzed with high performance liquid chromatography (HPLC). All 11 M. purpureus strains and 4 M. ruber strains could produce citrinin, while a M. purpureus strain and 9 M. ruber strains could produce MK. The contents of MK and citrinin in fermented rice produced by 5 M. ruber strains met the standards of functional red yeast rice (QB/T 2847—2007). The results from this study provide valuable information for modifying standards of related functional red yeast rice.
