摘要
功能红曲产品中的Monacolin-K包括酸型和内酯型两种成分。采用TLC法,以60%乙腈溶液作为提取剂,V(氯仿):V(甲醇):V(氨水)=25:3:1作为展开剂,以10%硫酸-乙醇溶液显色,紫外检测波长为365nm,可同步检测酸型和内酯型莫奈呵啉K。该法适用于任何含莫奈呵啉K的样品的检测,特别适用于大批量经常性的定性或半定量检测莫奈呵啉K。
The TLC works in the following conditions: The solvent system was chloroform: methanol: ammonium hydroxide =25:3:1 (volume ratio); monitoring the TLC under 365 nm after heating it with a slight coating of the charring reagent 10% (volume fraction) H2SO4 ethanol on the TLC plate. Under such condition,the two forms of Monacolin K (acid form and lactone farm of Monacolin K) can be determined simuhaneously. The present TLC method is suitable for the routine qualitative and semi-quantitative analysis of the bulk materials containing Monacolin K.
