Humulus
''Humulus'', or hop, is a small genus of flowering plants in the family Cannabaceae. The hop is native to temperate regions of the Northern Hemisphere. Hops are the female flowers (seed cones, strobiles) of the hop species '' H. lupulus''; as a main flavor and aroma ingredient in many beer styles, ''H. lupulus'' is widely cultivated for use by the brewing industry. Description Although frequently referred to in American literature as the hops "vine", it is technically a bine; unlike vines, which use tendrils, suckers, and other appendages for attaching themselves, bines have stout stems with stiff hairs to aid in climbing. In British literature the term "vine" is generally reserved for the grape genus ''Vitis''. ''Humulus'' is described as a twining perennial herbaceous plant which sends up new shoots in early spring and dies back to the cold-hardy rhizome in autumn. Hop shoots grow very rapidly, and at the peak of growth can grow per week. Hop bines climb by wrapping clockwise ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Humulus Lupulus
''Humulus lupulus'', the common hop or hops, is a species of flowering plant in the hemp family, Cannabaceae. It is a perennial, herbaceous climbing plant which sends up new shoots in early spring and dies back to a cold-hardy rhizome in autumn. It is dioecious (having separate male and female plants) and native to West Asia, Europe and North America. As the female cone-shaped flowers (hops) are used to preserve and flavor beer, the species is widely cultivated for the brewing industry. Description ''Humulus lupulus'' is a perennial herbaceous plant up to tall, living up to 20 years. It has simple leaves with 3–5 deep lobes that can be opposite or alternate. The species is triggered by the longer summer days to flower, usually around July or August in the Northern Hemisphere. The plant is dioecious, with male and female flowers on separate plants. The fragrant flowers are wind-pollinated. The staminate (male) flowers do not have petals, while the pistillate (female) flowers ...

Humulus Japonicus
''Humulus japonicus'', known as Japanese hops, is an ornamental plant in the family Cannabaceae. Some authorities have it as a synonym of ''Humulus scandens''. Originally native to East Asian countries such as China, Japan, Korea, and extending its habitat to Vietnam, it was imported to North America in the late 19th century as an ornamental. Since its arrival in North America, it has spread widely. It can be found throughout the Northeastern U.S. and eastern Canada, and considered an invasive species in North America. It also features on the list of invasive alien species of Union Concern since 2019. This means it can no longer be imported in the European Union. Additionally, it has become illegal to plant it, breed it, transport it, or bring it into the wild in all Member States. Nomenclature ''Humulus japonicus'' (syn. ''H. scandens'', ''Antidesma scandens'') is known by the common name of "Asian hop","Japanese hop", or "wild hop". The plant is called ''lü cao'' ( zh, t=� ...

Hops
Hops are the flowers (also called seed cones or strobiles) of the hop plant ''Humulus lupulus'', a member of the Cannabaceae family of flowering plants. They are used primarily as a bittering, flavouring, and stability agent in beer, to which, in addition to bitterness, they impart floral, fruity, or citrus flavours and aromas. Hops are also used for various purposes in other beverages and herbal medicine. The hops plants have separate female and male plants, and only female plants are used for commercial production. The hop plant is a vigorous climbing herbaceous perennial, usually trained to grow up strings in a field called a hopfield, hop garden (in the South of England), or hop yard (in the West Country and United States) when grown commercially. Many different varieties of hops are grown by farmers around the world, with different types used for particular styles of beer. The first documented use of hops in beer is from the 9th century, though Hildegard of Bingen, 300 y ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Cannabaceae
Cannabaceae is a small family of flowering plants, known as the hemp family. As now circumscribed, the family includes about 170 species grouped in about 11 genera, including '' Cannabis'' (hemp), '' Humulus'' (hops) and '' Celtis'' (hackberries). ''Celtis'' is by far the largest genus, containing about 100 species.Stevens, P.F. (2001 onwards"Cannabaceae" ''Angiosperm Phylogeny Website'', retrieved 2014-02-25 Cannabaceae is a member of the Rosales. Members of the family are erect or climbing plants with petalless flowers and dry, one-seeded fruits. Hemp (''Cannabis'') and hop (''Humulus'') are the most economically important species. Other than a shared evolutionary origin, members of the family have few common characteristics; some are trees (e.g. ''Celtis''), others are herbaceous plants (e.g. ''Cannabis''). Description Members of this family can be trees (e.g. '' Celtis''), erect herbs (e.g. '' Cannabis''), or twining herbs (e.g. '' Humulus''). Leaves are often more or l ...

Xanthohumol
Xanthohumol is a natural product found in the female inflorescences of ''Humulus lupulus'', also known as hops. This compound is also found in beer and belongs to a class of compounds that contribute to the bitterness and flavor of hops. Xanthohumol is a prenylated chalconoid, biosynthesized by a type III polyketide synthase (PKS) and subsequent modifying enzymes. Biosynthesis Xanthohumol is a prenylated chalconoid derived from a plant type III PKS, and is synthesized in the glandular trichromes of hop cones. Phenylalanine, L-Phenylalanine serves as the starting material, which is converted to cinnamic acid by the PLP-dependent Phenylalanine ammonia-lyase, phenylalanine ammonia lyase. Cinnamic acid is oxidized by Trans-cinnamate 4-monooxygenase, cinnamate-4-hydroxylase and loaded onto coenzyme A (CoA) by 4-Coumarate-CoA ligase, 4-coumarate CoA ligase to yield Coumaroyl-CoA, 4-hydroxy-cinnamoyl CoA, the starter unit for PKS extension. This molecule is extended three times with Mal ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
