Chalcones from Humulus lupulus
Phytochemistry, 1989Abstract Extracts of Humulus lupulus yielded two known compounds, isoxanthohumol and xanthohumol, and two new chalcones, 3′-(isoprenyl)-2′,4-dihydroxy-4′,6′-dimethoxychalcone and 2′,6′-dimethoxy-4,4′-dihydroxychalcone. Their structures were established by spectral methods.

[Flavonoids from Humulus lupulus].
Zhongguo Zhong yao za zhi = Zhongguo zhongyao zazhi = China journal of Chinese materia medica, 2013Nine compounds were isolated and purified by column chromatographic techniques including macroporous resin, silica gel, ODS, Sephadex LH-20, and preparative reversed-phase HPLC. Their structures were elucidated as taxifolin (1), naringenin (2), chalconaringenin (3), acacetin (4), quercetin 3-O-beta-D-galactopyranoside (5), 6-prenylnaringenin (6 ...

Neuropharmacological Activity of Humulus Lupulus L.
2009Abstract The traditional use of hops in the treatment of sleep disturbances has been supported by experimental studies performed in rodents, as described in the present chapter. An inhibitory influence on the central nervous system was suggested by the finding of a reduction in locomotor behavior together with an enhancement of pentobarbital ...

Prenylflavonoids from Humulus lupulus
Phytochemistry, 1997Abstract Five flavonoids were isolated from the resin part of the female inflorescences of Humulus lupulus , together with four known hop flavonoids, i.e. xanthohumol, 2′,4′,6′,4-tetrahydroxy-3′- C -prenylchalcone, iso-xanthohumol and 6-prenylnaringenin.

We demonstrate the possibility to apply SSR-PCR to the identification and differentiation of hop(Humulus lupulus L.) genotypes of the Ukrainian selection using microsatellite loci. Phyllo-genetic bonds between 13 Ukrainian cultivars of hop on the basis of SSR-markers are investigated.

In the shoots of Humulus lupulus L., secretory canals of schizogenous- lysigenous type were discovered. It has been found that functional schizogenous-lysigenous canals are active on the stage of rapid shoot growth. It has been established that in the tissues of vegetative and generative organs of hop plants, transitional forms of lacticifers are ...

Sedating effects of Humulus lupulus L. extracts
Phytomedicine, 2006It was the aim of the study to check ethanolic and CO2 extracts from Humulus lupulus for sedating activity. Both preparations reduced the spontaneous locomotor activity, increased the ketamine-induced sleeping time and reduced body temperature, confirming a central sedating effect.

The characterisation of xyloglucanase inhibitors from Humulus lupulus
Phytochemistry, 2013Phytopathogenic fungi secrete a powerful arsenal of enzymes that are potentially active against each polysaccharide component of the plant cell wall. To defend themselves, plants synthetise a variety of molecules that inhibit the activity of cell wall-degrading enzymes.

Pharmacognostic and pharmacological profile of Humulus lupulus L.
Journal of Ethnopharmacology, 2008The present review describes the morphological, phytochemical and ethnopharmacological aspects of Humulus lupulus L. (Cannabinaceae) and summarizes the most interesting findings obtained in the preclinical and clinical research related to the plant. The female inflorescences of Humulus lupulus (hops), well-known as bittering agent in brewing industry ...
