ABSTRACT
Objective:To establish a random amplified polymorphism DNA(RAPD) method for classification of origin fungi of the Chinese traditional medicine Red Kojic. Methods:The genome DNA of 7 ordinary species Monascus including M. purpureus and a strain of Aspergillus terreus were extracted by CTAB. The content of DNA was assayed doubly by fluorescence intensity of ethidium bromide (EB) and spectrometer. Amplification products were detected by agarose gel electrophoresis and clustering analysis by PHYLIP 3.5c. Results:A characteristic pattern was produced depend on one of the 10 primers screened from 60 random primers, and the genome was amplified. The diversities of the fingerprint patterns of Monascus was obvious, by which Monascus can be distinguished easily. The results were consistent with that of morphologic study. Conclusion:RAPD is a new assay technique. It can be used to classify and identify of Monascus fungi. [
