Terminalia catappa and subspathulata are two species of the Combretaceae family medium to large forest trees. The fruits T. known for edible nuts commonly as tropical almonds due their similarity in taste with commerce. Therefore, chemical profiles were examined ascertain potential value food or health uses. Gas chromatography-mass spectrometry (GCMS) ultrahigh-pressure liquid chromatography-el...

Over recent years the binding ability of the molecular chaperone cpn60 (GroEL14) and its co-chaperone cpn10 (GroES7) has been reported to occur under an assortment of specific conditions from the use of non-hydrolysable ATP analogues (namely adenosine 5'-[gamma-thio]triphosphate) to requiring hydrolysable ATP for any interaction to occur. We have investigated this further using the molecular hy...

An extracellular tannase was produced from solid-state cultures of Aspergillus niger. The enzyme was purified to homogeneity from the cell-free culture broth by preparative isoelectric focusing and by FPLC using anion-exchange and gel-filtration chromatography. SDS-PAGE analysis as well as gel localization studies of purified tannase indicated the presence of two enzyme forms, with molecular ma...

Most orally administered polyphenols are metabolized, with very little absorbed as aglycones and/or unchanged forms. Metabolic and pharmacokinetic studies are therefore necessary to understand the pharmacological mechanisms of polyphenols. Jumihaidokuto (JHT), a traditional Japanese medicine, has been used for treatment of skin diseases including inflammatory acne. Because JHT contains various ...

Tellimagrandin I and chebulinic acid, two hydrolysable tannins, have been shown to exert anti-tumor properties. Dysfunctional gap junctional communication (GJIC) has been recognized as being involved in carcinogenesis. The human cervical carcinoma HeLa cells have been reported to be deficient in functional GJIC. In present study, we investigated whether tellimagrandin I and chebulinic acid migh...

The present paper deals with the structure, occurrence and biological activity of ellagitannins. Ellagitannins belong to the class of hydrolysable tannins, they are esters of hexahydroxydiphenoic acid and monosaccharide (most commonly glucose). Ellagitannins are slowly hydrolysed in the digestive tract, releasing the ellagic acid molecule. Their chemical structure determines physical and chemic...

Tannins have been used to trigger positive effects on ruminal metabolism and increase ruminant production efficiency, since they the supply of dietary protein in small intestine. Increasing levels tannic acid a sorghum-based diet feeding behavior five Holstein/Zebu crossbred lactating dairy cows was evaluated. They were subjected 5 × Latin square experimental design, with fivelevels tannin as d...

Plant polyphenolics are receiving increased attention for their influences on belowground processes. Tannins are of particular interest because of their predominance in natural systems, their wide variation in both quality and quantity, and their protein-binding abilities. Current theory holds that simple phenolics increase microbial activity by acting as carbon substrates, while larger tannins...
