Xanthohumol is a major prenylated, hydrophobic flavonoid found in the female inflorescences of the hop plant (Humulus lupulus L.). In this study, we examined the effects of xanthohumol-rich hop extract containing 17.8% xanthohumol and 12.4% isoxanthohumol on the differentiation and adipogenesis of 3T3L1 cells. We observed that the extract inhibited the differentiation of 3T3L1 cells and intrace...

J. Am. Soc. Brew. Chem. 68(3):125-131, 2010 Genetic information for male and female hop accessions is limited, hampering parental selection to maximize offspring productivity. Our objective was to determine whether amplified fragment length polymorphism (AFLP)derived genetic distance (GDmm) estimates and coancestry estimates from pedigrees (GSped) between parental pairs could be used to predict...

Several plant extracts were evaluated against obliquebanded leafroller larvae to determine potential toxicity and antifeedant effects. Two of the plant extracts exhibited contact toxicity; the LC50 value of Humulus lupulus extract against 3 rd instar larvae was 24.5 μg / insect. In a no choice context, larval survivorship was reduced 23 57 % after feeding on a meridic pinto bean diet treated wi...
