Inhibitors of nitric oxide production from hops (Humulus lupulus L.).
Nitric oxide (NO) plays an important role in many inflammatory responses and is also involved in carcinogenesis. In the present study, we investigated the inhibitory effect of extracts from Humulus lupulus L. on both the production of NO and the expression of inducible NO synthase (iNOS) in mouse macrophage RAW 264.7 cells. The production of NO was induced by a combination of lipopolysaccharide...
متن کاملNew prenylchalcones from the hops of Humulus lupulus.
Two new prenylchalcones, xanthohumol C and D, together with two known prenylchalcone derivatives, xanthohumol (1) and 5''-(2''-hydroxyisopropyl)-dihydrofurano-[2'',3''-b]-4,4'-dihydroxy-6'-methoxy-chalcone (4) were isolated and identified from the hops of Humulus lupulus L. The structures of xanhohumol C and D were elucidated as 5''-hydroxy-6'',6''-dimethyl-dihydropyrano-[2'',3''-b]-4,4'-dihydr...
متن کاملAnti-inflammatory acylphloroglucinol derivatives from Hops (Humulus lupulus).
The polyphenol-enriched fraction of an ethanolic hops extract (Humulus lupulus) was separated to provide four acylphloroglucinol-glucopyranosides (1-4). 1-(2-Methylpropanoyl)phloroglucinol-glucopyranoside 1 has been isolated from hops before, whereas 1-(2-methylbutyryl)phloroglucinol-glucopyranoside 2, known as multifidol glucoside, and 1-(3-methylbutyryl)phloroglucinol-glucopyranoside 3 were f...
متن کاملGenetic and epigenetic stability of cryopreserved and cold-stored hops (Humulus lupulus L.).
Conventional cold storage and cryopreservation methods for hops (Humulus lupulus L.) are available but, to our knowledge, the genetic and epigenetic stability of the recovered plants have not been tested. This study analyzed 51 accessions of hop using the molecular techniques, Random Amplified DNA Polymorphism (RAPD) and Amplified Fragment Length Polymorphism (AFLP), revealing no genetic variat...
متن کاملPhotosynthetic activity of selected genotypes of hops (Humulus lupulus L.) in critical periods for yield formation
This paper evaluates the influence of genotype on the photosynthetic activity of hops in the period critical for generating yield. Results over three years from measuring the photosynthesis rate statistically show an increase in the photosynthetic activity of hop plants in the flowering stage. The average photosynthetic rates from measurements on the second date (BBA 65) in the years 2007, 2008...
