Xanthohumol (XN) is the major prenylated flavonoid of the female inflorescences (cones) of the hop plant (Humulus lupulus). It is also a constituent of beer, the major dietary source of prenylated flavonoids. Recent studies have suggested that XN may have potential cancer-chemopreventive activity, but little is known about its metabolism. We investigated the biotransformation of XN by rat liver...

Humulus lupulus L. (hops) is a popular botanical dietary supplement used by women as a sleep aid and for postmenopausal symptom relief. In addition to its efficacy for menopausal symptoms, hops can also modulate the chemical estrogen carcinogenesis pathway and potentially protect women from breast cancer. In the present study, an enriched hop extract and the key bioactive compounds [6-prenylnar...

INTRODUCTION Menopause is a critical stage in every woman's life. It can cause a distressing time for women by creating various vasomotor symptoms (VMS). Phytoestrogens can potentially exert various favourable effects and alleviate VMS in postmenopausal women. The hop (Humulus lupulus L.) contains 8-prenylnaringenin (8-PN), the most potent phytoestrogen known to date. The hop is eight times str...

Xanthohumol (XN)* is a prenylated chalcone found at high concentrations in hop cones (Humulus lupulus L.). XN has been characterized as a promising cancer chemopreventive lead structure that acts via a broad spectrum of bioactivities. This chapter summarizes the anti-proliferative and apoptosis-inducing potential of XN and gives a detailed overview of underlying mechanisms and pathways targeted...

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...

Rhamnus prinoides (gesho) which is belongs to the family Rhamnaceae and order Rhamnales a dicotyledonous angiosperm plant. In Ethiopia, plant utilized as bittering agent in local alcoholic beverages. Due its substance compositions it could have potential be used raw material for However, knowledge of hop substitute during beverage production limited. The major goal this research was investigate...
