Identifying the origin fungi of the traditional Chinese medicine Hongqu with capillary gas chromatography method / 第二军医大学学报

ABSTRACT

Objective：To establish a capillary gas chromatography(CGC) method for identifying the origin fungi of traditional Chinese medicine Hongqu. Methods：The volatile components of 7 species of Monascus including M. purpureus Went, M.aurantiacus Lee, M. serorubesceus　Sato, M. albidus Sato, M. barkeri Dangerd, M. ruber van　Tieghem, and　M.fuliginosus　Sato were analyzed by capillary gas chromatography method. Inlet temperature and detector temperature were 280℃，temperature program were 130℃,5 min→10℃/min→200℃, 10 min FID was used for detection. Results：The variety and contents of the volatility components in Monascus had obvious differences which can be distinguished easily by the main fingerprint peaks within 20 min. Conclusion：This method is useful to identify of Monascus fungi.
