FRACTIONATION OF THE β FRACTION OF HOP RESINS [PDF]
Journal of the Institute of Brewing, 1961 Products of oxidation of lupulones and humulones have been fractionated by the chromatostrip method and by column chromatography; lupulones are not readily transformed to hexane-insoluble material, but fractions corresponding to δ resin have been obtained from humulones.

The sedative effect of non-alcoholic beer in healthy female nurses. [PDF]
PLoS ONE, 2012 IntroductionThe hop (Humulus lupulus L.), a component of beer, is a sedative plant whose pharmacological activity is principally due to its bitter resins, in particular to the α-acid degradation product 2-methyl-3-buten-2-ol.

Modeling of synthesis and flow properties of propylene-diene copolymers [PDF]
, 2014 Copolymerization with nonconjugated dienes offers an attractive route for introducing long-chain branching in polypropylene. From a simplified set of rate equations for such copolymerization with a metallocene catalyst, we derive the probabilities of ...

Hop proanthocyanidins for the fining of beer [PDF]
, 2015 Fining agents are used in the clarification of beers; they help to reduce the time required to sediment suspended yeast cells and ensure the clarity and colloidal stability of beer. Following an adventitious observation during dry-hopping experiments, we

Dynamics of Isomerization of Hop Alpha-Acids and Transition of Hop Essential Oil Components in Beer
Acta Chimica Slovenica, 2020 Hops’ unique composition of essential oil components and bitter resins are crucial for beer aroma, which is important to consumers’ acceptance of beer. In this experiment the same wort was divided into four portions and each was hopped differently.

FURTHER STUDIES ON THE OXIDATION OF HOP RESINS [PDF]
Journal of the Institute of Brewing, 1966 The autoxidation of humulone, isohumulone, colupulone and cohulupone has been studied using chromatography on an ion-exchange resin. Humulone gave a mixture of products which were largely insoluble in light petroleum whereas most of the products obtained by autoxidation of colupulone were soluble in that solvent.
