[Distinguish of the original fungi of the Chinese traditional medicine, hongqu with gas chromatography fuzzy clustering analytical method].
OBJECTIVE
To establish a gas chromatography fuzzy clustering analytical method for classifying of origin fungi of the Chinese traditional medicine, Hongqu.


METHODS
The volatile and nonvolatile components of 7 ordinary species of Monascus including M. aurantiacus Lee, etc. were analyzed by capillary gas chromatog raphy using FID: Inlet temperature 280 degrees C, detector temperature 280 degrees C, temperature program 130 degrees C, 5 min-->10 degrees C.min-1-->200 degrees C, 10 min.


RESULTS
In the peak number and contents of volatile and nonvolatile components of Monascus exist obviously differences through which Monascus can be distinguished easily by the main fingerprint peaks within 20 minutes.


CONCLUSIONS
The capillary gas chromatography fuzzy clustering analytical method is useful to the identification of Monascus fungi.
