Antiviral and antioxidant activity of a hydroalcoholic extract from Humulus lupulus L.
Female strobilus inflorescences (hops or cones) from Humulus lupulus L., commonly named hop cones or hops, are widely used in the brewing industry as preservative and flavouring additives, as well as in traditional medicine as remedies for mild sleeping disorders and as bitter stomachic. Polyphenolic compounds, mainly prenylflavonoids (viz. xanthohumol), catechins and procyanidins represent some of the characteristic phytoconstituents.
