Cinnamtannin B1
Cinnamtannin B1 is a condensed tannin found in ''Cinnamomum verum''. It is a type A proanthocyanidin. Cinnamon could have some pharmacological effects in the treatment of type 2 diabetes mellitus and insulin resistance. The plant material used in the study was mostly from Chinese cinnamon (see Chinese cinnamon's medicinal uses). Recent studies in phytochemistry have indicated that cinnamtannin B1 isolated from ''C. Verum'' bears possible therapeutic effect on type 2 diabetes, with the exception of the postmenopausal patients studied on ''Cinnamomum aromaticum ''Cinnamomum cassia'', called Chinese cassia or Chinese cinnamon, is an evergreen tree originating in southern China, and widely cultivated there and elsewhere in South and Southeast Asia (India, Indonesia, Laos, Malaysia, Thailand, and Vietnam) ...''. Cinnamtannin B1 possesses several phenolic hydroxyl groups and is reported to exhibit antioxidant property, antimicrobial activities, and anti-platelet aggreg ...

Condensed Tannin
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, proteracacinidins, proguibourtinidins or prorobinetidins. All of the above are formed from flavan-3-ols, but flavan-3,4-diols, called (leucoanthocyanidin) also form condensed tannin oligomers, e.g. leuco-fisetinidin form profisetinidin, and flavan-4-ols form condensed tannins, e.g. 3',4',5,7-flavan-4-ol form proluteolinidin (luteoforolor). One particular type of condensed tannin, found in grape, are procyanidins, which are polymers of 2 to 50 (or more) catechin units joined by carbon-carbon bonds. These are not ...

Cinnamomum Verum
''Cinnamomum verum'', called true cinnamon tree or Ceylon cinnamon tree, is a small evergreen tree belonging to the family Lauraceae, native to Sri Lanka. The inner bark of several other ''Cinnamomum'' species are also used to make cinnamon, but ''C. verum'' has a more subtle flavor. Description ''Cinnamomum verum'' trees are 10–15 metres (30–50 feet) tall. The leaves are ovate-oblong in shape and 7–18 cm (3–7 inches) long. The flowers, which are arranged in panicles, have a greenish color and a distinct odour. The fruit is a purple 1cm drupe containing a single seed. Cultivation The old botanical synonym for the tree, ''Cinnamomum zeylanicum'', is derived from Sri Lanka's former name, Ceylon. Sri Lanka still produces 80–90% of the world's supply of ''C. verum'', which is also cultivated on a commercial scale in the Seychelles, Madagascar and Tanzania. Cultivars There are several different cultivars of ''Cinnamomum verum'' based on the taste of bark: * Type 1 – si, ...

Type A Proanthocyanidin
A type proanthocyanidins are a specific type of proanthocyanidins, which are a class of flavonoid. Proanthocyanidins fall under a wide range of names in the nutritional and scientific vernacular, including oligomeric proanthocyanidins, flavonoids, polyphenols, condensed tannins, and OPCs. Proanthocyanidins were first popularized by French scientist Jacques Masquelier. Distribution in plants A-type linkage is a less common feature in proanthocyanidins with both 4β→8 ( B-type) and 2β→O→7 interflavanoid bonds. A-type proanthocyanidin glycosides can be isolated from cocoa liquor. Dimers * Procyanidin A1 is an epicatechin-(2β→7,4β→8)-catechin dimer. * Procyanidin A2 is a dimeric (-)epicatechin. Other A-type proanthocyanidins can be found in cranberries, cinnamon, peanut skins and ''Geranium niveum''. Chemistry B-type procyanidins (catechin dimers) can be converted to A-type procyanidins by radical oxidation. Fragmentation patterns for A-type proanthocyanidins in ...

Diabetes Mellitus Type 2
Type 2 diabetes, formerly known as adult-onset diabetes, is a form of diabetes mellitus that is characterized by high blood sugar, insulin resistance, and relative lack of insulin. Common symptoms include increased thirst, frequent urination, and unexplained weight loss. Symptoms may also include increased hunger, feeling tired, and sores that do not heal. Often symptoms come on slowly. Long-term complications from high blood sugar include heart disease, strokes, diabetic retinopathy which can result in blindness, kidney failure, and poor blood flow in the limbs which may lead to amputations. The sudden onset of hyperosmolar hyperglycemic state may occur; however, ketoacidosis is uncommon. Type 2 diabetes primarily occurs as a result of obesity and lack of exercise. Some people are genetically more at risk than others. Type 2 diabetes makes up about 90% of cases of diabetes, with the other 10% due primarily to type 1 diabetes and gestational diabetes. In type 1 diabet ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Insulin Resistance
Insulin resistance (IR) is a pathological condition in which cell (biology), cells fail to respond normally to the hormone insulin. Insulin is a hormone that facilitates the transport of glucose from blood into cells, thereby reducing blood glucose (blood sugar). Insulin is released by the pancreas in response to carbohydrates consumed in the diet. In states of insulin resistance, the same amount of insulin does not have the same effect on glucose transport and blood sugar levels. There are many causes of insulin resistance and the underlying process is still not completely understood, but sulfate depletion may be the important factor. Risk factors for insulin resistance include obesity, sedentary lifestyle, family history of diabetes, various health conditions, and certain medications. Insulin resistance is considered a component of the metabolic syndrome. There are multiple ways to measure insulin resistance such as fasting insulin levels or glucose tolerance tests, but these are ...

Cinnamomum Aromaticum
''Cinnamomum cassia'', called Chinese cassia or Chinese cinnamon, is an evergreen tree originating in southern China, and widely cultivated there and elsewhere in South and Southeast Asia (India, Indonesia, Laos, Malaysia, Thailand, and Vietnam). It is one of several species of ''Cinnamomum'' used primarily for their aromatic bark, which is used as a spice. The buds are also used as a spice, especially in India, and were used by the ancient Romans. The tree grows to tall, with greyish bark and hard, elongated leaves that are long and reddish when young. Origin and types Chinese cassia is a close relative to Ceylon cinnamon ('' C. verum''), Saigon cinnamon (''C. loureiroi''), also known as "Vietnamese cinnamon", Indonesian cinnamon ('' C. burmannii''), also called "korintje", and Malabar cinnamon ('' C. citriodorum'') from Malabar region in India. In all five species, the dried bark is used as a spice. Chinese cassia's flavor is less delicate than that of Ceylon cinnamon. It ...

Phytochemistry
Phytochemistry is the study of phytochemicals, which are chemicals derived from plants. Phytochemists strive to describe the structures of the large number of secondary metabolites found in plants, the functions of these compounds in human and plant biology, and the biosynthesis of these compounds. Plants synthesize phytochemicals for many reasons, including to protect themselves against insect attacks and plant diseases. The compounds found in plants are of many kinds, but most can be grouped into four major biosynthetic classes: alkaloids, phenylpropanoids, polyketides, and terpenoids. Phytochemistry can be considered a subfield of botany or chemistry. Activities can be led in botanical gardens or in the wild with the aid of ethnobotany. Phytochemical studies directed toward human (i.e. drug discovery) use may fall under the discipline of pharmacognosy, whereas phytochemical studies focused on the ecological functions and evolution of phytochemicals likely fall under the disci ...

Procyanidins
Procyanidins are members of the proanthocyanidin (or condensed tannins) class of flavonoids. They are oligomeric compounds, formed from catechin and epicatechin molecules. They yield cyanidin when depolymerized under oxidative conditions. See the box below entitled "Types of procyanidins" for links to articles on the various types. Distribution in plants Procyanidins, including the lesser bioactive / bioavailable polymers (4 or more catechines), represent a group of condensed flavan-3-ols that can be found in many plants, most notably apples, maritime pine bark, cinnamon, aronia fruit, cocoa beans, grape seed, grape skin, and red wines of ''Vitis vinifera'' (the common grape). However, bilberry, cranberry, black currant, green tea, black tea, and other plants also contain these flavonoids.USDA, August 2004USDA Database for the Proanthocyanidin Content of Selected Foods PDF summary accessed from main USDA pag Page accessed July 31, 2015 Procyanidins can also be isolated from ''Q ...
