In this study, the molecular weight of the anti-cholesterol agent from Monacus kaoliang
KB9 strain analysis by LC-MS was found to be 355 and 359 (data not shown), which differed from a previous report (Li et al., 2004). However, the previous study of Dontri et al. (2008) showed that the red mold rice of Monascus kaoliang KB9
played a dual function by significantly decreasing the cholesterol of egg yolk and serum, while increasing yolk pigment.
