  • Five host-specific pathotoxins, ACRL toxins II, III, III′, IV and IV′, were isolated from the culture broth of Alternaria citri, the fungus causing brown spot disease of rough lemon
  • Chemical and spectral studies indicated that the ACRL minor toxins were a group of analogous compounds of different chain lengths all of which have a α-pyrone group, in contrast to the dihydro-α-pyrone group in toxin I
  • The dihydropyrone group in ACRL toxin I was correlated with high biological activity
