High Molecular Weight Plant Polyphenolics (Tannins) as Biological Antioxidants.
Ann E. Hagerman,Ken M. Riedl,G.A. Jones,K.N. Sovik,N.T. Ritchard,P.W. Hartzfeld,T.L. Riechel +6 more
TL;DR: The results suggest that tannins, which are found in many plant-based foods and beverages, are potentially very important biological antioxidants.

The specificity of proanthocyanidin-protein interactions.
Ann E. Hagerman,Larry G. Butler +1 more
TL;DR: The specificity of the interaction was investigated using a competitive binding assay to compare directly the affinities of various proteins and synthetic polymers for the tannin obtained from Sorghum bicolor (Lin.) Moench, indicating that this proanthocyanidin interacts quite selectively with protein and protein-like polymers.

Protein precipitation method for the quantitative determination of tannins
Ann E. Hagerman,Larry G. Butler +1 more
TL;DR: The tannin content of crude plant exts. was detd. by adding the sample to a std. soln. as discussed by the authors, and measuring the absorbance at 510 nm after adding FeCl3.

Role of Tannins in Defending Plants Against Ruminants: Reduction in Protein Availability
Charles T. Robbins,T. A. Hanley,Ann E. Hagerman,O. Hjeljord,D. L. Baker,Charles C. Schwartz,William W. Mautz +6 more
TL;DR: It is hypothesized that soluble phenolics that do not inhibit digestion but are absorbed and reduce intake through their toxicity are more important in defending some plant parts against ruminants than are digestion-reducing tannins.

Role of tannins in defending plants against ruminants: reduction in dry matter digestion?
TL;DR: The saliva composition of mule deer (a mixed feeder that commonly consumes browse) and domestic cattle and sheep (predominant grazers) are compared, and the higher potential of the deer saliva to neutralize tannins is related to their feeding habits.
