Condensed tannins

Proceedings of the 29th International Conference on Computer Graphics and Interactive Techniques. Electronic Art and Animation Catalog., 2002
Created for an Ocean Spray video news release, this animation demonstrates how condensed tannins, a component of cranberry juice, prevent urinary tract infections. Most urinary tract infections are caused by the bacteria e. Coli and their toxins. Fimbria on the bacteria attach to receptors on the bladder wall, facilitating sustained, close exposure to ...

Structure analysis of condensed tannin from rice straw and its inhibitory effect on Staphylococcus aureus

, 2020
To reduce the production cost of bioethanol and improve the utilization rate of straw resources, more high value-added products have to be found and applied. In this study, tannins were considered as a high-value by-product.

Interactions of tea tannins and condensed tannins with proteins

Journal of Pharmaceutical and Biomedical Analysis, 2010
Binding parameters for the interactions of four types of tannins: tea catechins, grape seed proanthocyanidins, mimosa 5-deoxy proanthocyanidins, and sorghum procyanidins (mDP=17), with gelatin and bovine serum albumin (BSA) have been determined from isothermal titration calorimetry data. Equilibrium binding constants determined for the interaction with

Standardization and quantification of total tannins, condensed tannin and soluble phlorotannins extracted from thirty-two drifted coastal macroalgae using high performance liquid chromatography

Bioresource Technology Reports, 2019
Tannins are important phytochemicals that provide protection against insect's infestation and have been utilized for various industrial uses. In this work we report the extraction, qualitative profile and quantification of the levels of total tannins ...

Condensed tannin purification and characterization of tannin-associated proteins

Journal of Agricultural and Food Chemistry, 1980
The conventional isolation method has been modified in order to minimize protein contamination of tannin purified from high tannin sorghum. The two unique steps of the new procedure are preliminary extraction of the ground grain with ethanol and treatment of the partially purified tannin with phenol to remove traces of noncovalently bound protein ...

Tolerance of acridids to ingested condensed tannin

Journal of Chemical Ecology, 1981
Four species of Acridoidea were fed on wheat leaves with and without the condensed tannin, quebracho. In no case was it deleterious to survival and growth at levels below about 10% dry weight on the food. Similarly, consumption, digestibility, and utilization of food were unaffected at up to 10% dry weight.

Condensed tannins from Myrica gale

Fitoterapia, 2000
From the aerial parts of the Myrica gale catechin, epicatechin, gallocatechin, epigallocatechin, epigallocatechin-3-O-gallate, gallocatechin-(4 alpha-8)-epicatechin, gallocatechin-(4 alpha-8)-epigallocatechin, and gallocatechin-(4 alpha-8)-gallocatechin-(4 alpha-8)-gallocatechin (1), were isolated.
