摘要: 红曲产品中可能含有桔霉素,已使我国的红曲出口受到很大影响。根据国内外对桔霉素的最新研究报告,采用薄层层析法,对红曲中桔霉素的提取方法和展开剂分别进行研究。结果表明,以酸性水溶液作为提取剂,以甲苯:乙酸乙酯:甲酸(6:3:1)为展开剂,桔霉素的分离检测效果较好。在此基础上对22个红曲样进行了分析,结果显示,大部分红曲都含桔霉素,但含量高低不一,从中获得桔霉素含量低而色价高的红曲霉菌株有3个。

Abstract: Citrinin was probably found in Honqqu (Monascus spp.) product, thus affected the Hongqu export of our conuntry.On the basis of the domestic and oversea up dated study reports, the extracting method and developer of Citrinin analysis inHongqu product have been researched. The results indicated that the effect of separation and detection of Citrinin was better byusing the acid resolution as the extractant and using Ethyll acetate: Toluene: Formic acid (6:3:1) as developer.On these bases ,22 Hongqu samples have been analysed. The results showed that most of Hongqu samples contained Citrinin at different level.However there were 3 strains of Monascus spp. that would have high color value and low Citrinin.

Key words: Hongqu, Monascus spp., Citrinin, TLC
