“1-Benzopyrans”  

1-Benzopyran

  In organic chemistry, 1-Benzopyrans are aromatic organic compounds in the pyrans subclass in the 6-member heterocyclic compounds class in the organoheterocyclic compound superclass, containing a bicyclic benzopyran compound made up of a benzene ring fused to a pyran ring, so that the oxygen atom is at the 1-position.
  Examples of 1-benzopyrans include:

“Ellagic Acids and Ellagic Acid derivatives”  

Ellagic Acid

  In organic chemistry, Ellagic acids are a class of aromatic organic compounds in the benzenoids superclass containing an ellagic acid moiety (4,4',5,5',6,6'-Hexahydroxydiphenic acid 2,6,2',6'-dilactone) or a derivative thereof.
  In phytochemistry, Ellagic Acid, a fused four ring polyphenol compound found in numerous plants, fruits and vegetables, may be produced from ellagitannins upon hydrolysis. **

“Aflatoxins”  

Aflatoxin

  In lipid science, Aflatoxins, as polyketides, are naturally occurring mycotoxins produced by primarily by some species of the fungus Aspergillus.
  Aflatoxin is one of the most potent carcinogens known to man, and has been linked to a wide variety of human health problems.
  Three main types of aflatoxin mycotoxins include:

• aflatoxin B group includes aflatoxin B1 and B2:
  • aflatoxin B1 (AFB1) is the most common aflatoxin
  • Aflatoxins B2
• aflatoxin G group includes aflatoxin G1 and aflatoxin G2:
  • Aflatoxins G1
  • Aflatoxins G2
• aflatoxin M group includes aflatoxins M1 and M2, that are metabolic products found in urine and milk produced by animals which have been given feed with aflatoxins in it.
  • aflatoxin M1 (AFM1)
  • Aflatoxins M2

• difurocoumarocyclopentenones

“Citrinin”  

  As a drug, Citrinin, a nephrotoxic mycotoxin, used as an antibiotic, is a benzopyran, derived from from Penicillium citrinum, Aspergillus niveus and others.
  Renal damage, vasodilatation, and bronchial constriction are some of the health effects associated with citrinin. **
