Insoluble Condensed Tannins of Canola/Rapeseed

Journal of Agricultural and Food Chemistry, 2000
The contents of soluble, SDS-extractable, and insoluble condensed tannins were determined in canola/rapeseed hulls from several varieties by utilizing the proanthocyanidin assay. The total amount of tannins in rapeseed/canola hulls ranged from 1913 to 6213 mg per 100 g of oil-free hulls.

Significance of the Condensed Tannins

1989
The condensed tannins are biologically significant natural products primarily because of their ready complexation with proteins. These compounds are particularly important flavor components, being responsible for the astringency of many fruits and vegetable products.

Dietary Intake of Hydrolyzable Tannins and Condensed Tannins to Regulate Lipid Metabolism

Mini-Reviews in Medicinal Chemistry, 2022
Abstract: Lipid metabolism disorder is a multifactor issue, which contributes to several serious health consequences, such as obesity, hyperlipidemia, atherosclerosis diabetes, non-alcoholic fatty liver, etc. Tannins, applied as naturally derived plants, are commonly used in the study of lipid metabolism disease with excellent safety and effectiveness

Inhibition of α-amylase activity by condensed tannins

Food Chemistry, 2011
The ability of grape seed procyanidins to inhibit α-amylase activity was studied using a colorimetric method. This ability was found to be related with the average degree of polymerisation of the tested procyanidins. These interactions were further evaluated by fluorescence quenching, dynamic light scattering (DLS) and nephelometry, in order to ...

The condensed tannins of Leptarrhena pyrolifolia

Phytochemistry, 1993
Abstract A proanthocyanidin (PA) polymer, a condensed tannin, was isolated, purified and characterized from the leaves of Leptarrhena pyrolifolia. The predominant extension units in the polymer were (−)-epicatechin and (+)-gallocatechin with traces of (−)-epigallocatechin. (+)-Catechin was the predominant terminal unit.

Analysis of condensed tannins: a review

Animal Feed Science and Technology, 2001
Abstract Plant condensed tannins (proanthocyanidins, PAs) have both positive and negative effects on feed digestibility and animal performance, depending both on the quantity and biological activity of the tannins that are present. In this review, the chemistry and analysis of condensed tannins (PAs) are examined. Our first focus is on the complexity

Condensed Tannins in Canola Hulls

Journal of Agricultural and Food Chemistry, 1994
The total content and the biological activity of tannins in canola hulls were determined in several samples of hulls of Westar, Cyclone, Excel, and Delta canola varieties. The contents of condensed tannins in canola hulls ranged from 14 to 1556 mg of catechin equivalents/100 g of hulls as determined by vanillin assay, up to 8 times more condensed ...

The condensed tannins (proanthocyanidins) in seagrasses

Aquatic Botany, 1984
Abstract In a survey of 29 species in the 12 seagrass genera, those in the Potamogetonaceae that characteristically have tannin cells in the leaves (Posidonioideae: Posidonia; Cymodoceoideae: Halodule, Syringodium, Cymodocea, Thalassodendron, Amphibolis) contained compounds with the Rf values and color reactions typical of condensed tannins.

CONDENSED TANNINS OF RAPESEED MEAL

Journal of Food Science, 1979
ABSTRACT The study was undertaken to determine the amount and nature of condensed tannins in rapeseed meal. No condensed tannins were found in rapeseed meats (endosperm plus germ). The hulls, however, yielded 0.1% condensed tannins by 70% aqueous acetone extraction, the bulk of the condensed tannins in the hulls being unextractable by
