Condensed tannins (proanthocyanidins, polyflavonoid tannins, catechol-type tannins, pyrocatecollic type tannins, non-hydrolyzable tannins or flavolans) are polymers formed by the condensation of flavans. They do not contain sugar residues.
They are called proanthocyanidins as they yield anthocyanidins when depolymerized under oxidative conditions. Different types of condensed tannins exist, such as the procyanidins, propelargonidins, prodelphinidins, profisetinidins, proguibourtinidins or prorobinetidins, formed from flavonoids structures corresponding to the related anthocyanins. One particular type of condensed tannin, found in grape, are procyanidins, which are polymers of 2 to 50 (or more) flavan-3-ol units joined by carbon-carbon bonds. These are not susceptible to being cleaved by hydrolysis.
While many hydrolyzable tannins and most condensed tannins are water-soluble, several tannins are also highly octanol-soluble. Some large condensed tannins are insoluble. Differences in solubilities are likely to affect their biological functions.

AgResearch featured on 3 News for the world-first discovery that condensed tannins in GM white clover may help increase livestock protein intake and reduce methane emissions.
The health benefits of muscadines and resveratrol http://www.muscadinex.com Shop with Amazon http://amzn.to/yPGBDf Made From 100% Muscadine Grape Seeds On The Family Vineyard. Most resveratrol supplements give an artificially high mega-dose of just that one isolated molecule. But because Muscadinex is made only from fresh muscadine grape seeds, you get the full natural spectrum of polyphenols, antioxidants and bioflavonoids. We think that's important because it's more balanced. And many scientists believe that the healthy molecules resveratrol, ellagic acid and quercetin have a synergistic effect too. In other words ... the different molecules that mother nature put in the muscadine grape help each other to make you healthier. So why is red wine, in moderation, healthy? Scientist...
Areca nut bunch hanging from the palm. Areca nut is the seed of the areca palm (Areca catechu), which grows in much of the tropical Pacific, Asia, and parts of Artocarpus heterophyllus fruits at tree. Areca catechu is the areca palm or areca nut palm betel palm, a species of palm which grows in much of the tropical Pacific, Asia, and parts of east Africa. The palm is believed to have originated in either Indonesia/Malaysia or the Philippines. Areca is derived from a local name from the Malabar Coast of India and catechu is from another Malay name for this palm, caccu. This palm is often called the betel tree because its fruit, the areca nut, is often chewed along with the betel leaf, a leaf from a vine of the Piperaceae family. It is a medium-sized and palm tree, growing straight to 20 ...
Cranberries are known to treat UTI. It has been proven to be very effective even to treat other health problems. It contains Proanthocyanidins which are also called as the tannins, a type of organic chemical compound, that have been condensed. These compounds have act a specific way of functioning which block the bacteria from attaching themselves to the surface, linings of the specific body part, especially the linings in the urethra.

Plantago is a genus of about 200 species of small, inconspicuous plants commonly called plantains. They share this name with the very dissimilar plantain, a kind of banana. Most are herbaceous plants, though a few are subshrubs growing to 60 cm (23.5 in) tall. The leaves are sessile, but have a narrow part near the stem which is a pseudo-petiole. They have three or five parallel veins that diverge in the wider part of the leaf. Leaves are broad or narrow, depending on the species. The inflorescences are borne on stalks typically 5--40 cm (2.25-15.75 in) tall, and can be a short cone or a long spike, with numerous tiny wind-pollinated flowers. Plantains are used as food plants by the larvae of some species of Lepidoptera (butterfly and moth) - see list of Lepidoptera that feed on pla...
A world-first GE discovery by New Zealand scientists could lead to more productive farms and reduced greenhouse gases by up to 10%. But activists and environmentalists warn genetic tinkering threatens New Zealand's clean green reputation. Scientific research has been unveiled that could cut greenhouse gas emissions from farms while boosting production at the same time. AgResearch says it's trying to make one of sheep and cattle's favourite foods, white clover, environmentally safer. Currently, the state institute says a white clover diet produces too little protein and too much methane gas. But discovering how to unlock condensed tannins in the plant could change all that, hiking meat or milk production and cutting greenhouse gases. The work is opposed by the Green Party and...
