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
