title: A new perylenequinone from a halotolerant fungus, Alternaria sp. M6.
abstract: OBJECTIVE
  To study the metabolites of a halotolerant fungus Alternaria sp. M6.
  
  
  METHODS
  The metabolites were isolated and purified by various chromatographic techniques. Their structures were determined on the basis of physical properties and spectroscopic data.
  
  
  RESULTS
  Nine compounds were isolated and identified as 8β-chloro-3, 6aα, 7β, 9β, 10-pentahydroxy-9, 8, 7, 6a-tetrahydroperylen-4(6aH)-one (1), alterperylenol (2), dihydroalterperylenol (3), adenine (4), adenosine (5), deoxyadenosine (6), guanosine (7), tryptophan (8), and hexadecanoic acid (9).
  
  
  CONCLUSIONS
  Compound 1 is a new perylenequinone.
