Alfred Rehder
Alfred Rehder (4 September 1863 in Waldenburg, Saxony – 25 July 1949 in Jamaica Plain, Massachusetts) was a German-American botanical taxonomist and dendrologist who worked at the Arnold Arboretum of Harvard University. He is generally regarded as the foremost dendrologist of his generation. Life Georg Alfred Rehder was born in the castle of Waldenburg to Thekla née Schmidt (1839–1897) and Paul Julius Rehder (1833–1917), the superintendent of parks and gardens of the principality of Schönburg-Waldenburg. Through his father, Rehder was introduced to the gardening profession. On his mother's side of the family, Rehder was likely descended from Henry, Duke of Anhalt-Köthen (1778–1847). Rehder broke off his attendance at the gymnasium in Zwickau in 1881 and did not pursue university studies, instead working for three years as an apprentice under the tutelage of his father. His professional career began in 1884 at the Berlin Botanical Garden. Here he was able to a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Taxus
''Taxus'' is a genus of coniferous trees or shrubs known as yews in the family Taxaceae. They are relatively slow-growing and can be very long-lived, and reach heights of , with trunk girth averaging . They have reddish bark, lanceolate, flat, dark-green leaves long and broad, arranged spirally on the stem, but with the leaf bases twisted to align the leaves in two flat rows either side of the stem. The oldest known fossil species are from the Early Cretaceous. Morphology The seed cones are highly modified, each cone containing a single seed long partly surrounded by a modified scale which develops into a soft, bright red berry-like structure called an aril, long and wide and open at the end. The arils are mature 6–9 months after pollination, and with the seed contained are eaten by thrushes, waxwings and other birds, which disperse the hard seeds undamaged in their droppings; maturation of the arils is spread over 2–3 months, increasing the chances of successful seed d ...

Taxus Celebica
''Taxus celebica'' is a large, evergreen shrub or tree of the yew family (Taxaceae), widespread in China at elevations up to 900 meters (3,000 feet). It is commonly called Chinese yew though the term also refers to the ''Taxus chinensis'' or ''Taxus sumatrana''. The tree is up to 14 m (46 ft) tall and wide and bushy when cultivated. The leaves are up to 4 centimeters (1.5 inches) long — broader than those of most other yews — and often end in a very small, sharp point. The underside of each leaf has two broad yellow stripes and is densely covered with minute projections. It is, along with other yew species, unsustainably harvested across Asia for their bark and needles, which contain a chemical used in the cancer medication Taxol Paclitaxel (PTX), sold under the brand name Taxol among others, is a chemotherapy medication used to treat a number of types of cancer. This includes ovarian cancer, esophageal cancer, breast cancer, lung cancer, Kaposi's sarcoma, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Taxus Sumatrana
''Taxus sumatrana'' is an evergreen shrub and one of the eight species of the yew. It is found in a number of countries, including Afghanistan, Tibet, Nepal, Sumatra, Philippines, Vietnam, India, Burma, Taiwan, and China, and is known both as the Taiwan yew and the Chinese yew. It is typically found at heights ranging from 400–3,100 mde Laubenfels, Miquel ''Taxus sumatrana'', 1978link retrieved on March 10, 2007 in subtropical forest and on highland ridges. It is a protected species in Taroko National Park in Taiwan. Appearance ''Taxus sumatrana'' is a wide trunked, bushy tree that grows to an average height of 14 m. Its leaves are 1.2–2.7 cm long and 2–2.5 mm wide, and grow in two ranks along the branches, abruptly spiralling into an apex at the tip, with a pale yellow-green colour on top, and light green underneath. The Chinese yew has fleshy seeds that ripen into a red colour, and a grey-red bark which exfoliates in irregular 1.5 mm thick flak ...

Paclitaxel
Paclitaxel (PTX), sold under the brand name Taxol among others, is a chemotherapy medication used to treat a number of types of cancer. This includes ovarian cancer, esophageal cancer, breast cancer, lung cancer, Kaposi's sarcoma, cervical cancer, and pancreatic cancer. It is administered by intravenous injection. There is also an albumin-bound formulation. Common side effects include hair loss, bone marrow suppression, numbness, allergic reactions, muscle pains, and diarrhea. Other serious side effects include heart problems, increased risk of infection, and lung inflammation. There are concerns that use during pregnancy may cause birth defects. Paclitaxel is in the taxane family of medications. It works by interference with the normal function of microtubules during cell division. Paclitaxel was first isolated in 1971 from the Pacific yew and approved for medical use in 1993. It is on the World Health Organization's List of Essential Medicines. It has been made from precu ...

Taxifolin
Taxifolin (5,7,3',4'-flavan-on-ol), also known as dihydroquercetin, belongs to the subclass flavanonols in the flavonoids, which in turn is a class of polyphenols. Stereocenters Taxifolin has two stereocenters on the C-ring, as opposed to quercetin which has none. For example, (+)-taxifolin has (2R,3R)-configuration, making it 1 out of 4 stereoisomers that comprise 2 pairs of enantiomers. Natural occurrences Taxifolin is found in non-glutinous rice boiled with adzuki bean (adzuki-meshi). It can be found in conifers like the Siberian larch, ''Larix sibirica'', in Russia, in ''Pinus roxburghii'', in ''Cedrus deodara'' and in the Chinese yew, '' Taxus chinensis var. mairei''. It is also found in the silymarin extract from the milk thistle seeds. Taxifolin is present in vinegars aged in cherry wood. Taxifolin, and flavonoids in general, can be found in many beverages and products. Specifically, taxifolin is found in plant-based foods like fruit, vegetables, wine, tea, and coco ...

Trees Of China
In botany, a tree is a perennial plant with an elongated stem, or trunk, usually supporting branches and leaves. In some usages, the definition of a tree may be narrower, including only woody plants with secondary growth, plants that are usable as lumber or plants above a specified height. In wider definitions, the taller palms, tree ferns, bananas, and bamboos are also trees. Trees are not a taxonomic group but include a variety of plant species that have independently evolved a trunk and branches as a way to tower above other plants to compete for sunlight. The majority of tree species are angiosperms or hardwoods; of the rest, many are gymnosperms or softwoods. Trees tend to be long-lived, some reaching several thousand years old. Trees have been in existence for 370 million years. It is estimated that there are some three trillion mature trees in the world. A tree typically has many secondary branches supported clear of the ground by the trunk. This trunk typically c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
