| Humulinones (cohumulinone, n-humulinone, and adhumulinone) || Alpha acids (cohumulone, humulone, and adhumulone) || Y || 66% as bitter as iso-alpha-acids || In hops, alpha-acids are degraded to humulinones in the presence of air, with higher temperatures leading to more rapid conversion.
|-
| tricyclooxyisohumulones A and B, deisopropyltricycloisohumulone, and tricycloperoxyisohumulone A || alpha-Alpha acids || ? || ? || Along with humulinones and 4'-hydroxy-allohumulinones, they are considered aging indicators of of hop oxidation.
|-
| Abeo-isohumulone || Humulinone || ? || Not reported; might contribute to bitterness of beers with high amounts of aged hops. || Derived from the oxidation of humulinone in hops. Found in naturally aged Saaz and Nugget hops over a long period of storage.
