Cytotoxic effect of commercial Humulus lupulus L. (hop) preparations – In comparison to its metabolomic fingerprint

Hops (Humulus lupulus L. Cannabaceae) is an economically important crop, that has drawn more attention in recent years due to its potential pharmaceutical applications. Bitter acids (prenylated polyketides) and prenylflavonoids are the primary phytochemical components that account for hops resins medicinal value. We have previously reported on utilizing untargeted NMR and MS metabolomics for an...

Predicting Offspring Performance in Hop (Humulus lupulus L

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...

Responses of Plasma Acetate Metabolism to Hop (Humulus lupulus L.) in Sheep

An isotope dilution method using [1-(13)C]sodium (Na) acetate was conducted to determine the effect of feeding hop (Humulus lupulus L.) residues on plasma acetate metabolism in six adult crossbred sheep. The sheep were fed 63 g/kg BW(0.75)/d of either mixed hay (MH-diet) of orchardgrass (Dactylis glomerata L.) and reed canarygrass (Phalaris arundinacea L.) at a 60:40 ratio or MH-diet and hop-re...

Artificially induced polyploidization in Humulus lupulus L. and its effect on morphological and chemical traits

Chemically induced polyploids were obtained by the colchicine treatment of shoot tips of Humulus lupulus L. 'Sybilla'. Flow cytometry revealed that most of the treatments resulted in the production of tetraploids. The highest number of tetraploids was obtained when explants were immersed in 0.05% colchicine for 48 h. A field experiment was conducted to compare diploid and tetraploid plants and ...
