The isomerization products of humulone


  • This is the 44th paper on hop constituents from our laboratory.


The substance known as “isohumulone” is in fact a mixture of four components. They were separated by C.C.D. According to a new nomenclature based mainly on the chemically related humulinic acids A,B, C etc. series they are the stereoisomers isohumulone A and B (IV and V) and alloisohumulone A and B (VI and VII).
