Stachyurus Himalaicus
''Stachyurus'' is the only genus in the flowering plant family Stachyuraceae, native to the Himalayas and eastern Asia. They are deciduous shrubs or small trees with pendent racemes of 4-petalled flowers which appear on the bare branches before the leaves. The plants have leaves with serrate margins. Pendunculagin, casuarictin, strictinin, casuarinin and casuariin are ellagitannins found in species in this genus. '' Stachyurus praecox'' from Japan, and the slightly later-flowering ''S. chinensis'' from China, are both cultivated as ornamental plants, valued for their exceptionally early flowering periods.

Stachyurus Praecox
''Stachyurus praecox'', early stachyurus, is a species of flowering plant in the family Stachyuraceae, native to Japan. It is a spreading deciduous shrub growing to tall by wide. Pendant, bell-shaped, primrose yellow flowers are borne on naked arching branches in winter and spring. They are followed by ovate leaves, which colour to pink or red before falling in autumn. The Latin specific epithet ''praecox'' means "early", referring to the exceptionally early flowering season. It was first described in 1836 by Philipp Franz von Siebold and Joseph Gerhard Zuccarini. This plant is cultivated as an ornamental subject in temperate parks and gardens, though rarely seen. It has gained the Royal Horticultural Society's Award of Garden Merit The Award of Garden Merit (AGM) is a long-established annual award for plants by the British Royal Horticultural Society (RHS). It is based on assessment of the plants' performance under UK growing conditions. History The Award of Garden Meri ... [...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.

Stachyurus Chinensis
''Stachyurus chinensis'' (中国旌节花), Chinese stachyurus, is a species of flowering plant in the family Stachyuraceae, native to China and Taiwan. It is a spreading deciduous shrub growing to tall by wide. Stiff, pendent racemes of bell-shaped, greenish-yellow flowers are borne on glossy, dark brown branches in winter and spring. It flowers two weeks later than the related ''S. praecox''. The flowers are followed by simple ovate leaves which colour to pink and red before falling in autumn. The Latin specific epithet ''chinensis'' means "from China". This is the most widely distributed species of the genus, and is found throughout southern and eastern China as well as the island of Taiwan. It is also highly variable, with some populations on the mainland more closely resembling ''S. himalaicus''. The two species may be better regarded as conspecific. This plant is cultivated as an ornamental subject in temperate parks and gardens. Although hardy, it prefers a sheltered ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ellagitannin
The ellagitannins are a diverse class of hydrolyzable tannins, a type of polyphenol formed primarily from the oxidative linkage of galloyl groups in 1,2,3,4,6-pentagalloyl glucose. Ellagitannins differ from gallotannins, in that their galloyl groups are linked through C-C bonds, whereas the galloyl groups in gallotannins are linked by depside bonds. Ellagitannins contain various numbers of hexahydroxydiphenoyl units, as well as galloyl units and/or sanguisorboyl units bounded to sugar moiety. In order to determine the quantity of every individual unit, the hydrolysis of the extracts with trifluoroacetic acid in methanol/water system is performed. Hexahydroxydiphenic acid, created after hydrolysis, spontaneously lactonized to ellagic acid, and sanguisorbic acid to sanguisorbic acid dilactone, while gallic acid remains intact. Ellagitannins generally form macrocycles, whereas gallotannins do not. Examples * Castalagin * Castalin * Casuarictin * Grandinin * Oenothein B from ...
