Compare of Monacolin K Detection Method in Lipid-Lowering Monascus Products

Abstract:

To accurately examine the amounts of Monacolin K（MK） in lipid-reducing Monascus products，in this paper we compared to the light industry standard of the People's Republic of China（2007），the health care food inspection and evaluation specification（2003），Taiwan food inspection method of MK（2012） and Zhu Hua et al. applied method. The results show that Zhu Hua et al. applied method was superior. MK linearity was good within 10~400 μg/mL，and addition recovery rate was 96.3%，RSD=1.6%. This method was simple，quick and accurate to examine the amounts of MK，with very great practical value.
