Anthraquinones,and the growing family of pyranoanthraquinones or anthrapyrans which occur mainly as C-glycosides.

Other polycyclic quinones,]anthraquinones, and their ring-A reduced analogues—the anthracyc-linones and angucyclinones—both of which exist in substantial num- bers. The smaller group of benz[.]napthacenequinones is also covered, and finally the extended polycyclic quinones including the ancient quincyte pigments.

Miscellaneous quinones,Included here are the rare group of thiopheno- and dithiophenobenzoquinones from archaebacteria, and the ansaquinone antibiotics elaborated mainly by . spp. The latter group contains benzoquinones and naphthoquinone units within a macrocyclic system; about a dozen new examples have been identified in the last decade.
