Dihydrostilbenoids
Dihydrostilbenoids (bibenzyls) are natural phenols formed from the dihydrostilbene ( bibenzyl) backbone. Examples Dihydro-resveratrol is a natural phenol with a bibenzyl structure found in wine. It is also a metabolite of trans-resveratrol formed in the intestine by the hydrogenation of the double bond by microflora. Combretastatin and combretastatin B-1 are two dihydrostilbenoids found in ''Combretum caffrum'', an African tree. Isonotholaenic acid is another dihydrostilbenoid found in the Andean fern '' Argyrochosma nivea''. Bibenzyls ( 3,4'-dihydroxy-5,5'-dimethoxybibenzyl, 3,3'-dihydroxy-5-methoxybibenzyl ( batatasin III)) can be found in the orchid '' Bulbophyllum vaginatum''. Bis(bibenzyls) and macrocyclic bis(benzyls) can be found in bryophytes, such as the compounds plagiochin E, 13,13'-O-isoproylidenericcardin D, riccardin H, marchantin E, neomarchantin A, marchantin A and marchantin B in the Chinese liverwort ''Marchantia polymorpha''.

Tyrol–South Tyrol–Trentino Euroregion
The Tyrol–South Tyrol–Trentino Euroregion (german: Europaregion Tirol–Südtirol–Trentino; it, Euregio Tirolo–Alto Adige–Trentino) is a Euroregion formed by three different regional authorities in Austria and Italy: the Austrian States of Austria, state of Tyrol (state), Tyrol (i.e. North Tyrol, North and East Tyrol) and the Italian autonomous Provinces of Italy, provinces of South Tyrol and Trentino. Overview The boundaries of the association correspond to the former County of Tyrol, Princely County of Tyrol, a crown land of the Habsburg monarchy (including the former Prince-bishoprics of Prince-Bishopric of Trent, Trent and Bishopric of Brixen, Brixen) which for centuries shaped life in the Alpine region, Alpine region. Excluded from the association due to a change of the province by the fascists, are Cortina d'Ampezzo, Cortina, Livinallongo del Col di Lana, Livinallongo, Colle Santa Lucia, Pedemonte, Valvestino and Magasa, Lombardy, Magasa, but they have v ...

Scorzonera Humilis
''Scorzonera humilis'', the viper's-grass, is a perennial plant. In Britain it is a rare plant, restricted to moist meadows, in Dorset and Warwick in England, and in South Wales. One unique class of stilbenoid derivative was first isolated from ''S. humilis''. They were named the tyrolobibenzyls after Tyrol in the eastern Alps, where the plant was collected. Description It differs from goat's-beard, ''Tragopogon pratensis'', in that it has short, pale green bracts, whereas in Goats Beard they are long and pointed. It grows 7 to 50 cm. The leaves are unbranched, elliptical-lanceolate. The flower heads are 2.5 cm wide, and deep yellow in colour. Flowers from May until July. The achenes An achene (; ), also sometimes called akene and occasionally achenium or achenocarp, is a type of simple dry fruit produced by many species of flowering plants. Achenes are monocarpellate (formed from one carpel) and indehiscent (they do not op ... are smooth ribbed, beakless ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Radula Kojana
The radula (, ; plural radulae or radulas) is an anatomical structure used by molluscs for feeding, sometimes compared to a tongue. It is a minutely toothed, chitinous ribbon, which is typically used for scraping or cutting food before the food enters the esophagus. The radula is unique to the molluscs, and is found in every class of mollusc except the bivalves, which instead use cilia, waving filaments that bring minute organisms to the mouth. Within the gastropods, the radula is used in feeding by both herbivorous and carnivorous snails and slugs. The arrangement of teeth ( denticles) on the radular ribbon varies considerably from one group to another. In most of the more ancient lineages of gastropods, the radula is used to graze, by scraping diatoms and other microscopic algae off rock surfaces and other substrates. Predatory marine snails such as the Naticidae use the radula plus an acidic secretion to bore through the shell of other molluscs. Other predatory marine snails ...
