Iridin
Iridin is an isoflavone, a type of flavonoid. It is the 7-glucoside of irigenin and can be isolated from several species of irises like orris root, ''Iris florentina'' or ''Iris versicolor'', also commonly known as the larger blue flag. It can also be found in ''Iris kemaonensis ''Iris kemaonensis'', the Kumaon iris, is a plant species in the genus '' Iris'', it is also in the subgenus '' Iris'' and in the section ''Pseudoregelia''. It is a rhizomatous perennial, from Tibetan China, Bhutan, India, Kashmir and Nepal. I ...''. The compound is toxic and these plants have been mentioned as causing poisoning in humans and animals.

Iris (plant)
''Iris'' is a flowering plant genus of 310 accepted species with showy flowers. As well as being the scientific name, ''iris'' is also widely used as a common name for all ''Iris'' species, as well as some belonging to other closely related genera. A common name for some species is 'flags', while the plants of the subgenus '' Scorpiris'' are widely known as 'junos', particularly in horticulture. It is a popular garden flower. The often-segregated, monotypic genera '' Belamcanda'' (blackberry lily, ''I. domestica''), '' Hermodactylus'' (snake's head iris, ''I. tuberosa''), and ''Pardanthopsis'' (vesper iris, '' I. dichotoma'') are currently included in ''Iris''. Three Iris varieties are used in the Iris flower data set outlined by Ronald Fisher in his 1936 paper ''The use of multiple measurements in taxonomic problems'' as an example of linear discriminant analysis.

Iris Versicolor
''Iris versicolor'' is also commonly known as the blue flag, harlequin blueflag, larger blue flag, northern blue flag, and poison flag, plus other variations of these names, and in Britain and Ireland as purple iris. It is a species of ''Iris'' native to North America, in the Eastern United States and Eastern Canada. It is common in sedge meadows, marshes, and along streambanks and shores. The specific epithet ''versicolor'' means "variously coloured". It is one of the three ''Iris'' species in the ''Iris'' flower data set outlined by Ronald Fisher in his 1936 paper "The use of multiple measurements in taxonomic problems" as an example of linear discriminant analysis. Description ''Iris versicolor'' is a flowering herbaceous perennial plant, growing high. It tends to form large clumps from thick, creeping rhizomes. The unwinged, erect stems generally have basal leaves that are more than wide. Leaves are folded on the midribs so that they form an overlapping flat fan. Th ...

Iris Kemaonensis
''Iris kemaonensis'', the Kumaon iris, is a plant species in the genus ''Iris'', it is also in the subgenus ''Iris'' and in the section ''Pseudoregelia''. It is a rhizomatous perennial, from Tibetan China, Bhutan, India, Kashmir and Nepal. It has light green or yellowish green leaves, that extend after flowering time. It has a short stem, 1–2 fragrant flowers that are purple, lilac, lilac-purple or pale purple. They also have darker coloured blotches or spots. It is cultivated as an ornamental plant in temperate regions. It is often known as ''Iris kumaonensis'', due to a publishing error. Description In China, there has been some confusion between '' Iris dolichosiphon'' (another ''Pseudoregelia iris'') and ''Iris kemaonensis'', they have similar flower forms, but ''Iris kemaonensis'' flowers are paler then ''Iris dolichosiphon'' but are strongly mottled, as well as a smaller perianth tube. It has short, thick rhizomes, which are gnarled and knobbly.British Iris Society (199 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Isoflavone
Isoflavones are substituted derivatives of isoflavone, a type of naturally occurring isoflavonoids, many of which act as phytoestrogens in mammals. Isoflavones are produced almost exclusively by the members of the bean family, Fabaceae (Leguminosae). Although isoflavones and closely related phytoestrogens are sold as dietary supplements, there is little scientific evidence for either the safety of long-term supplementation or of health benefits from these compounds. Some studies have identified potential risks from high intake of isoflavones, such as in women with a history of breast cancer, but this concern has not been substantiated with high-quality clinical research. Organic chemistry and biosynthesis Isoflavone is an isomer of flavone, which is chromone substituted with a phenyl group in the 2-position. In isoflavone, the phenyl group is in the 4-position. Isoflavone is of liminted interest per se, but substituted derivatives are of nutritional interest. Substituted deriv ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Glucoside
A glucoside is a glycoside that is derived from glucose. Glucosides are common in plants, but rare in animals. Glucose is produced when a glucoside is hydrolysed by purely chemical means, or decomposed by fermentation or enzymes. The name was originally given to plant products of this nature, in which the other part of the molecule was, in the greater number of cases, an aromatic aldehydic or phenolic compound (exceptions are Jinigrin and Jalapin or Scammonin). It has now been extended to include synthetic ethers, such as those obtained by acting on alcoholic glucose solutions with hydrochloric acid, and also the polysaccharoses, e.g. cane sugar, which appear to be ethers also. Although glucose is the most common sugar present in glucosides, many are known which yield rhamnose or iso-dulcite; these may be termed pentosides. Much attention has been given to the non-sugar parts (aglyca) of the molecules; the constitutions of many have been determined, and the compounds synthesi ...

Iris Florentina
The identity of the plant first described by Carl Linnaeus as ''Iris florentina'' remains unclear, . In horticulture, it has been treated as a white-flowered variant of ''Iris'' × ''germanica'', under names such as ''Iris germanica'' nothovar. ''florentina'', ''Iris'' × ''germanica'' var. ''florentina'' and ''Iris'' × ''germanica'' 'Florentina'. ''Iris florentina'' has also been treated as the correct name for the true species also known as ''Iris albicans'' Lange. It is cultivated as an ornamental plant in temperate regions almost worldwide and is a rhizomatous perennial from southern Europe, mainly Italy (including the city of Florence) and France. It has a thick violet-scented rhizome, sword-like green or grey-green semi-evergreen leaves, a tall branched stem, and many flowers that are white and tinged or flushed with blue, pale blue, or lavender in spring or summer, and a white and yellow beard. It is also grown to produce orris-root, a scented substance used in perfumes, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
