中文摘要:

为准确测定降脂红曲类产品中Monacolin K（MK）的质量浓度。作者对中华人民共和国轻工行业标准（2007）、保健食品检验与评价技术规范（2003版）、台湾食品中MK检验方法（2012）以及其它方法进行比较。确定朱华等的检测方法较优，MK在质量浓度10~400 μg/mL范围内线性良好，加标回收率为96.3%，方法精密度RSD=1.6%。该方法简单、快捷，能够比较准确地反映红曲类产品中不同构型MK质量浓度，具有很高的实用价值。

英文摘要:

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.
