Oligostilbene
Oligostilbenoids (oligo- or polystilbenes) are oligomeric forms of stilbenoids. Some molecules are large enough to be considered polyphenols and constitute a class of tannins. Examples Dimers * Ampelopsin A * Epsilon-viniferin * Pallidol * Quadrangularin A Trimers * α-Viniferin * Ampelopsin E * ''trans''-Diptoindonesin B * Gnetin H Tetramers * cajyphenol A * cajyphenol B * Flexuosol A * Hemsleyanol D * Hopeaphenol * Vaticanol B * R2-Viniferin (syn. Vitisin A) Modified * Diptoindonesin C can be isolated from the bark of '' Shorea pinanga'' Other * Diptoindonesin F can be isolated from the bark of ''Shorea gibbosa'' Glycosides * Diptoindonesin A Diptoindonesin A is a C- glucoside of ε-viniferin isolated from the two Dipterocarpaceae '' Shorea seminis'' and ''Dryobalanops aromatica ''Dryobalanops aromatica'', commonly known as Borneo camphor, camphor tree, Malay camphor, or Sumatran c ...

Vitis Amurensis
''Vitis amurensis'', the Amur grape, is a species of grape native to the Asian continent. Its name comes from the Amur Valley in Russia and China. It is very resistant to frost, but is not tolerant to drought. Selections vary, but as a species it has strong resistance to anthracnose and ripe rot, and moderately strong resistance to downy mildew and powdery mildew. Botanical description A vine with stem 5–10 cm in diameter and typically spreading to 15–18 m, rarely up to 20–25 meters. Tendrils capable of wrapping around things will entwine the branches of neighbouring plants or anything else they can use for support. The bark is dark, scaly and with vertical stripes on old shoots. Young shoots are green, often with a reddish hue, reddish-brown in autumn. The leaves vary greatly in shape. They can be solid, three- or five-lobed, ovate or rounded, arched at the base. The size ranges from 9 to 25 cm with sharp edges and rounded-triangular serrate teeth. The surf ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pentamer
A pentamer is an entity composed of five sub-units. In chemistry, it applies to molecules made of five monomers. In biochemistry, it applies to macromolecules, in particular to pentameric proteins, made of five proteic sub-units. In microbiology, a pentamer is one of the proteins composing the polyhedral protein shell that encloses the bacterial micro-compartments known as carboxysomes. In immunology, an MHC pentamer is a reagent used to detect antigen-specific CD8+ T cells. See also * penta prefix * -mer suffix * ''Pentamerous Metamorphosis'', an album by Global Communication * Pentamery (botany), having five parts in a distinct whorl of a plant structure * Pentamerous can also refer to animals, such as crinoids Crinoids are marine animals that make up the class Crinoidea. Crinoids that are attached to the sea bottom by a stalk in their adult form are commonly called sea lilies, while the unstalked forms are called feather stars or comatulids, which are ...

Resveratrol
Resveratrol (3,5,4′-trihydroxy-''trans''-stilbene) is a stilbenoid, a type of natural phenol, and a phytoalexin produced by several plants in response to injury or when the plant is under attack by pathogens, such as bacteria or fungi. Sources of resveratrol in food include the skin of grapes, blueberries, raspberries, mulberries, and peanuts. Although commonly used as a dietary supplement and studied in laboratory models of human diseases, there is no high-quality evidence that resveratrol improves lifespan or has a substantial effect on any human disease. Research Resveratrol has been studied for its potential therapeutic use, with little evidence of anti-disease effects or health benefits in humans. Cardiovascular disease There is no evidence of benefit from resveratrol in people who already have heart disease. A 2018 meta-analysis found no effect on systolic or diastolic blood pressure; a sub-analysis revealed a 2 mmHg decrease in systolic pressure only from res ...
