Iris Marsica
''Iris marsica'' is a plant species in the genus ''Iris'', it is also in the subgenus ''Iris''. It is a rhizomatous perennial, from the Apennine Mountains, in Italy. It has glaucous, sickle-shaped or curved, light green leaves, slender stem with 2 branches, and 3 violet, light blue violet, dark violet, and dark purple flowers. It was only found and described since 1973, and is not yet in general cultivation. It was once thought to be a form of Iris germanica, but has different morphological characteristics and different chromosomal differences. Description It is similar in form to ''Iris germanica'', but it has more curved leaves (or sickle-shaped,) greener, and longer leaves, the stem is less glaucous,British Iris Society (1997) and it has less scarious (membranous) spathes. It has a thick rhizome, with many stoloniferous and fibrous branches. The rhizomes grow at ground level. It has herbaceous, (or deciduous), falcate (sickle-shaped), light green and slightly glaucous lea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Tepals
A tepal is one of the outer parts of a flower (collectively the perianth). The term is used when these parts cannot easily be classified as either sepals or petals. This may be because the parts of the perianth are undifferentiated (i.e. of very similar appearance), as in ''Magnolia'', or because, although it is possible to distinguish an outer whorl of sepals from an inner whorl of petals, the sepals and petals have similar appearance to one another (as in '' Lilium''). The term was first proposed by Augustin Pyramus de Candolle in 1827 and was constructed by analogy with the terms "petal" and "sepal". (De Candolle used the term ''perigonium'' or ''perigone'' for the tepals collectively; today, this term is used as a synonym for ''perianth''.) p. 39. Origin Undifferentiated tepals are believed to be the ancestral condition in flowering plants. For example, '' Amborella'', which is thought to have separated earliest in the evolution of flowering plants, has flowers with undif ...

Phylogeny
A phylogenetic tree (also phylogeny or evolutionary tree Felsenstein J. (2004). ''Inferring Phylogenies'' Sinauer Associates: Sunderland, MA.) is a branching diagram or a tree showing the evolutionary relationships among various biological species or other entities based upon similarities and differences in their physical or genetic characteristics. All life on Earth is part of a single phylogenetic tree, indicating common ancestry. In a ''rooted'' phylogenetic tree, each node with descendants represents the inferred most recent common ancestor of those descendants, and the edge lengths in some trees may be interpreted as time estimates. Each node is called a taxonomic unit. Internal nodes are generally called hypothetical taxonomic units, as they cannot be directly observed. Trees are useful in fields of biology such as bioinformatics, systematics, and phylogenetics. ''Unrooted'' trees illustrate only the relatedness of the leaf nodes and do not require the ancestral root to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Xanthone
Xanthone is an organic compound with the molecular formula O 6H4sub>2CO. It is a white solid. In 1939, xanthone was introduced as an insecticide and it currently finds uses as ovicide for codling moth eggs and as a larvicide. Xanthone is also used in the preparation of xanthydrol, which is used in the determination of urea levels in the blood. It can also be used as a photocatalyst. Synthesis Xanthone can be prepared by the heating of phenyl salicylate: Six methods have been reported for synthesizing xanthone derivatives: *The Michael-Kostanecki method uses an equimolar mix of a polyphenol and an ''O''- hydroxybenzoic acid, which are heated with a dehydrating agent. *The Friedel-Crafts method has a benzophenone intermediate. *The Robinson-Nishikawa method is a variant of the Hoesch synthesis but with low yields. *The Asahina-Tanase method synthesizes some methoxylated xanthones, and xanthones with acid-sensitive substituents. *The Tanase method is used to synthesiz ...

Isoflavonoid
Isoflavonoids are a class of flavonoid phenolic compounds, many of which are biologically active. Isoflavonoids and their derivatives are sometimes referred to as phytoestrogens, as many isoflavonoid compounds have biological effects via the estrogen receptor. Medically, isoflavonoids and related compounds have been used in many dietary supplements but the medical and scientific community is generally skeptical of their use. Recently, some natural isoflavonoids have been identified as toxins, including biliatresone which may cause biliary atresia when infants are exposed to the plant product. The isoflavonoid group is broad, and includes many structurally similar groups, including: * isoflavones * isoflavanones * isoflavans * pterocarpans * rotenoids Isoflavonoids are derived from the flavonoid biosynthesis pathway via liquiritigenin or naringenin. Chemical makeup While flavonoids (in the narrow sense) have the 2-phenylchromen-4-one backbone, isoflavonoids have the 3-phenylc ...

Flavonoid
Flavonoids (or bioflavonoids; from the Latin word ''flavus'', meaning yellow, their color in nature) are a class of polyphenolic secondary metabolites found in plants, and thus commonly consumed in the diets of humans. Chemically, flavonoids have the general structure of a 15-carbon skeleton, which consists of two phenyl rings (A and B) and a heterocyclic ring (C, the ring containing the embedded oxygen). This carbon structure can be abbreviated C6-C3-C6. According to the IUPAC nomenclature, they can be classified into: *flavonoids or bioflavonoids * isoflavonoids, derived from 3-phenyl chromen-4-one (3-phenyl-1,4- benzopyrone) structure *neoflavonoids, derived from 4-phenyl coumarine (4-phenyl-1,2- benzopyrone) structure The three flavonoid classes above are all ketone-containing compounds and as such, anthoxanthins (flavones and flavonols). This class was the first to be termed bioflavonoids. The terms flavonoid and bioflavonoid have also been more loosely used to descri ...
