BACKGROUND Tannins are large polyphenolic polymers and are known to bind proteins, limiting their digestibility, but are also excellent antioxidants. Numerous studies investigating the functional properties of sorghum tannin have been conducted by comparing grain samples from different sorghum lines without considering the other intrinsic characteristics of the grain. The purpose of this study ...

The effect of dietary condensed tannins (proanthocyanidins) on rat fecal bacterial populations was ascertained in order to determine whether the proportion on tannin-resistant bacteria increased and if there was a change in the predominant bacterial populations. After 3 weeks of tannin diets the proportion of tannin-resistant bacteria increased significantly (P < 0.05) from 0.3% +/- 5.5% to 25....

LIM, S. H., DARAH, I. & JAIN, K. 2006. Antimicrobial activities of tannins extracted from Rhizophora apiculata barks. Tannin which was extracted from barks of Rhizophora apiculata was further separated into hydrolysable and condensed tannin. The results of the study revealed that only hydrolysable tannin showed significant antibacterial and antiyeast activities but not antifungal activity. The ...

Grain sorghum silage tannin content effect was evaluated on milk production and chemical composition of Argentinean Holstein bred cows, and it are described dry matter (DM) and crude protein (CP) in situ digestion parameters and effective degradability. The base diet was constituted by alfalfa pasture, maize silage, and a protein – mineral supplement, differing in three treatments based on high...

Majority of regular synthetic antibiotics are in the process of being labeled out-dated owing to multi drug resistance among pathogens. Consequently researchers are devoting interest towards identification and isolation of potent antibacterial compounds from available herbal sources. Aim: The present study was aimed at evaluation of tannin levels, antioxidant potential and antibacterial activit...

UNLABELLED OBJECTIVES AND MATERIALS AND METHODS: Medicinal plants constitute an important source of potential therapeutic agents for diabetes and hyperlipidemia. The purpose of present study was to investigate the effect of leaf extract of Moringa oleifera on inhibition of alpha-glucosidase and pancreatic alpha-amylase related to diabetes mellitus. Moreover, the study was also determined in vit...
