Epimedium Wushanense
''Epimedium wushanense'' , the Wushan fairy wings, is a flowering plant species in the genus ''Epimedium''. Chemistry ''E. wushanense'' contains a number of flavanoids. 37 compounds were characterized from the underground and aerial parts of the plant. Among them, 28 compounds were prenylflavonoids. The predominant flavonoid, epimedin C, ranged from 1.4 to 5.1% in aerial parts and 1.0 to 2.8% in underground parts. It also contains wushanicaritin and wushankaempferol. Seven flavonoids named diphylloside A, epimedoside A, epimedin C, icariin, epimedoside C, icarisoside A, desmethylanhydroicaritin, as well as oleanolic acid can be isolated from the roots.

Tsun Shen Ying
A ''cun'' (), often glossed as the ''Chinese inch'', is a traditional Chinese units of measurement, Chinese unit of length. Its traditional measure is the width of a person's thumb at the knuckle, whereas the width of the two forefingers denotes 1.5 cun and the width of four fingers (except the thumb) side-by-side is 3 cuns. It continues to be used to chart acupuncture points on the human body, and, in various uses for traditional Chinese medicine. The cun was part of a larger decimal system. A cun was made up of 10 fen (unit), fen, which depending on the period approximated lengths or widths of millet grains, and represented one-tenth of a chi (unit), chi ("Chinese foot"). In time the lengths were standardized, although to different values in different jurisdictions. (See chi (unit) for details.) In Hong Kong, using the traditional standard, it measures ~3.715 cm (~1.463 in) and is written "tsun". In the twentieth century in the Republic of China (1912–194 ...

Epimedium
''Epimedium'', also known as barrenwort, bishop's hat, fairy wings, horny goat weed, or yin yang huo (), is a genus of flowering plants in the family Berberidaceae. The majority of the species are endemic to China, with smaller numbers elsewhere in Asia, and a few in the Mediterranean region. ''Epimedium'' species are deciduous or evergreen hardy perennials. The majority have four-parted "spider-like" flowers in spring. The species used as a dietary supplement is ''Epimedium grandiflorum''. It contains icariin, which is a weak PDE5 inhibitor ''in vitro''. Its clinical effects are unknown. There is little clinical evidence, but it is thought to have erectogenic properties and is found in some men's sexual health supplements. Description Species of ''Epimedium'' are herbaceous perennials, growing from an underground rhizome. Their growth habits are somewhat variable. Some have solitary stems, others have a "tufted" habit, with multiple stems growing close together. There may ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Prenylflavonoid
Prenylated flavonoids or prenylflavonoids are a sub-class of flavonoids. They are widely distributed throughout the plant kingdom. Some are known to have phytoestrogenic or antioxidant properties. They are given in the list of adaptogens in herbalism. Chemically they have a prenyl group attached to their flavonoid backbone. It is usually assumed that the addition of hydrophobic prenyl groups facilitate attachment to cell membranes. Prenylation may increase the potential activity of its original flavonoid. Monoprenyl isoflavone epoxidase is a key enzyme in fungal ''Botrytis cinerea'' metabolism of prenylated flavonoids. Many prenylflavonoids appear to have anticancer activity in vitro. Prenylchalcones, prenylflavones, prenylflavonols and prenylflavanones are classes of prenylflavonoids. Examples 6-Prenylnaringenin, 6-geranylnaringenin, 8-prenylnaringenin and isoxanthohumol can be found in hops and beer. Of the prenylflavonoids, 8-prenylnaringenin is the most potent phytoest ...

Icariin
Icariin is a chemical compound classified as a prenylated flavonol glycoside, a type of flavonoid. It is the 8-prenyl derivative of kaempferol 3,7-''O''-diglucoside. The compound has been isolated from several species of plant belonging to the genus ''Epimedium'' which are commonly known as horny goat weed, Yin Yang Huo, and ''Herba epimedii''. Extracts from these plants are reputed to produce aphrodisiac effects, and are used in traditional Chinese medicine Traditional Chinese medicine (TCM) is an alternative medical practice drawn from traditional medicine in China. It has been described as "fraught with pseudoscience", with the majority of its treatments having no logical mechanism of action ... to enhance erectile function. However, clinical trial data are lacking to support these claims. References {{Flavonol PDE5 inhibitors Flavonol glucosides Flavonol rhamnosides Prenylflavonoids Phenol ethers ...

Epimedoside C
Phellamurin, a flavonoid, is the 7-O-β-D-glucopyranoside, 8-C-prenyl derivative of the flavan-on-ol Aromadendrin, and may be seen as the 7-O-glucoside of noricaritin. Being a flavanonol, it has two stereocenters on the C-ring, so four stereoisomers of phellamurin are possible. It can be found in '' Commiphora africana'' and in ''Phellodendron amurense''. Related compounds 6"′-O-acetyl phellamurin is found in the leaves of ''Phellodendron japonicum ''Phellodendron amurense'' is a species of tree in the family Rutaceae, commonly called the Amur cork tree.
