Alnus Sieboldiana
''Alnus sieboldiana'' (オオバヤシャブシ in Japanese) is an alder species found on the islands of Honshū, Shikoku, and Suwanose-jima in Japan. ''A. sieboldiana'' contains the ellagitannins alnusiin, tellimagrandin I, pedunculagin, casuarinin, casuariin and 2,3-O-(S)-hexahydroxydiphenoyl-D-glucose. The Latin specific epithet ''sieboldiana'' refers to German physician and botanist Philipp Franz von Siebold Philipp Franz Balthasar von Siebold (17 February 1796 – 18 October 1866) was a German physician, botanist and traveler.

Alnus Sieboldiana MHNT
Alders are trees comprising the genus ''Alnus'' in the birch family Betulaceae. The genus comprises about 35 species of monoecious trees and shrubs, a few reaching a large size, distributed throughout the north temperate zone with a few species extending into Central America, as well as the northern and southern Andes. Description With a few exceptions, alders are deciduous, and the leaves are alternate, simple, and serrated. The flowers are catkins with elongate male catkins on the same plant as shorter female catkins, often before leaves appear; they are mainly wind-pollinated, but also visited by bees to a small extent. These trees differ from the birches (''Betula'', another genus in the family) in that the female catkins are woody and do not disintegrate at maturity, opening to release the seeds in a similar manner to many conifer cones. The largest species are red alder (''A. rubra'') on the west coast of North America, and black alder (''A. glutinosa''), native ...

Pedunculagin
Pedunculagin is an ellagitannin. It is formed from casuarictin via the loss of a gallate group. Natural occurrence Pedunculagin is found in plants in orders in the clade Rosidae. It can be found the pericarp of pomegranates (''Punica granatum''), in the family Lythraceae, in the order Myrtales. It is also found in plants in the order Fagales such as walnuts (''Juglans regia'') in the family Juglandaceae, in ''Alnus sieboldiana'' and in the Manchurian alder ('' Alnus hirsuta var. microphylla''), both species in the family Betulaceae and it is one of the main oak wood ellagitannins along with castalagin, vescalagin, grandinin and roburins A-E (genus ''Quercus'', in the family Fagaceae). It is also found in the Indian gooseberry (''Phyllanthus emblica''), a plant in the family Phyllanthaceae, in the order Malpighiales. Galloyl pedunculagin can be found in ''Platycarya strobilacea''. Research Pedunculagin is a highly active carbonic anhydrase inhibitor ''in vitro''. Chemistry ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Endemic Flora Of Japan
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example '' Cytisus aeolicus'' is an endemite of the Italian flora. '' Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Philipp Franz Von Siebold
Philipp Franz Balthasar von Siebold (17 February 1796 – 18 October 1866) was a German physician, botanist and traveler. He achieved prominence by his studies of Japanese flora (plants), flora and fauna (animals), fauna and the introduction of Western medicine in Japan. He was the father of the first female Japanese doctor educated in Western medicine, Kusumoto Ine. Career Early life Born into a family of doctors and professors of medicine in Würzburg (then in the Bishopric of Würzburg, later part of Bavaria), Siebold initially studied medicine at the University of Würzburg from November 1815, where he became a member of the German Student Corps, Corps Moenania Würzburg. One of his professors was Franz Xaver Heller (1775–1840), author of the ' ("Flora of the Grand Duchy of Würzburg", 1810–1811). Ignaz Döllinger (1770–1841), his professor of anatomy and physiology, however, most influenced him. Döllinger was one of the first professors to understand and tr ...

Botanical Name
A botanical name is a formal scientific name conforming to the '' International Code of Nomenclature for algae, fungi, and plants'' (ICN) and, if it concerns a plant cultigen, the additional cultivar or Group epithets must conform to the ''International Code of Nomenclature for Cultivated Plants'' (ICNCP). The code of nomenclature covers "all organisms traditionally treated as algae, fungi, or plants, whether fossil or non-fossil, including blue-green algae ( Cyanobacteria), chytrids, oomycetes, slime moulds and photosynthetic protists with their taxonomically related non-photosynthetic groups (but excluding Microsporidia)." The purpose of a formal name is to have a single name that is accepted and used worldwide for a particular plant or plant group. For example, the botanical name ''Bellis perennis'' denotes a plant species which is native to most of the countries of Europe and the Middle East, where it has accumulated various names in many languages. Later, the plant was intro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Casuarinin
Casuarinin is an ellagitannin. It is found in the pericarp of pomegranates (''Punica granatum''). It is also found in ''Casuarina'' and ''Stachyurus'' species and in ''Alnus sieboldiana''. It is an isomer of casuarictin. It is a highly active carbonic anhydrase inhibitor. Biosynthesis In some plants including oak and chestnut, the ellagitannins are formed from 1,2,3,4,6-pentagalloyl-glucose and further elaborated via oxidative dehydrogenation (tellimagrandin II and casuarictin formations). After conversion of casuarictin to pedunculagin, the pyranose ring of the glucose opens and the family of compounds including casuariin, casuarinin, castalagin, and castlin Castalin is an ellagitannin. It can be found in oak wood and in ''Melaleuca quinquenervia ''Melaleuca quinquenervia'', commonly known as the broad-leaved paperbark, paper bark tea tree, punk tree or niaouli, is a small- to medium-sized tree o ..., vescalagin and vescalin forms.

Tellimagrandin I
Tellimagrandin I is an ellagitannin found in plants, such as ''Cornus canadensis'', ''Eucalyptus globulus'', ''Melaleuca styphelioides'', ''Rosa rugosa'', and walnut. It is composed of two galloyl and one hexahydroxydiphenyl groups bound to a glucose residue. It differs from Tellimagrandin II only by a hydroxyl group instead of a third galloyl group. It is also structurally similar to punigluconin and pedunculagin, two more ellagitannin monomers. Tellimagrandin I has been shown to restore antioxidant enzyme activity in glucose- and oxalate-challenged rat cells and affects Cu(II)- and Fe(II)-dependent DNA strand breaks. It has hepatoprotective effects on carbon tetrachloride- and d-galactosamine-stressed HepG2 cells and enhances peroxisomal fatty acid beta-oxidation in liver, increasing mRNA expression of PPAR alpha, ACOX1, and CPT1A. It enhances gap junction communication and reduces tumor phenotype in HeLa cells and inhibits invasion of HSV-1 and HCV similar to eugenii ...

Japanese Language
is spoken natively by about 128 million people, primarily by Japanese people and primarily in Japan, the only country where it is the national language. Japanese belongs to the Japonic or Japanese- Ryukyuan language family. There have been many attempts to group the Japonic languages with other families such as the Ainu, Austroasiatic, Koreanic, and the now-discredited Altaic, but none of these proposals has gained widespread acceptance. Little is known of the language's prehistory, or when it first appeared in Japan. Chinese documents from the 3rd century AD recorded a few Japanese words, but substantial Old Japanese texts did not appear until the 8th century. From the Heian period (794–1185), there was a massive influx of Sino-Japanese vocabulary into the language, affecting the phonology of Early Middle Japanese. Late Middle Japanese (1185–1600) saw extensive grammatical changes and the first appearance of European loanwords. The basis of the standard dialect moved f ...
