The study’s aim was to develop a beverage incorporated with Terminalia chebula Retz., locally known as Haritaki, having gastro-intestinal motility improving properties. objectives of the study were beverage, check its acceptability by conducting sensory evaluation and chemically analyzing for quality assessment testing anti-oxidant properties presence gallic acid, i.e., hydrolysable tannin pres...

Tannin, isolated from cotton bracts, inhibits chloride secretion in airway epithelium. In bovine tracheal epithelial cells, tannin (25 μg/ml) blunted isoproterenol (Iso)-stimulated adenosine 3',5'-cyclic monophosphate (cAMP) accumulation. Inhibition was time and dose dependent, with 52 ± 5% (mean ± SE, n = 6) inhibition at 60 min and 82 ± 9% ( n = 3) inhibition at 8 h. Inhibition was reversible...

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...

Epilobium angustifolium has been traditionally used to treat of a number of diseases; however, not much is known regarding its effect on innate immune cells. In this study, we report that extracts of E. angustifolium activated functional responses in neutrophils and monocyte/macrophages. Activity-guided fractionation, followed by mass spectroscopy and NMR analysis, resulted in the identificatio...

Nontuberculous mycobacteria (NTM), including Mycobacterium avium complex (MAC), cause opportunistic chronic pulmonary infections. Notably, MAC susceptibility is regulated by various factors, including the host immune system. Persimmon (Ebenaceae Diospyros kaki Thunb.) tannin is a condensed tannin composed of a polymer of catechin groups. It is well known that condensed tannins have high antioxi...

This research tested the effects of paper birch, Betula papyrifera Marshall, condensed tannin on larval performance of the whitemarked tussock moth,Orgyia leucostigma (J. E. Smith). We conducted laboratory bioassays on Þfth stadium larvae. Larvae were reared on one of three diets: control (no condensed tannin), moderate condensed tannin (8.8% dry mass), and high condensed tannin (17.6% dry mass...

We examined the effects of tannin on a generalist herbivorous insect, the common cutworm (Spodoptera litura). The dosage effect was estimated by measuring the growth performance of the cutworm when the larvae were fed artificial diets containing different amounts of synthesized tannin. We used artificial diets to exclude the effects of non-tannin defense mechanisms in plant foliage. Indices of ...

Tannins have a number ofdetrimental biological effects and these include interference with normal growth and metabolism if they are present in the feed of various animals. Proline-rich proteins (PRPs) in saliva have been shown to provide protection against tannin, but little is known about the mechanism of protection and interaction of other salivary proteins with tannin. To identify tannin-bin...

The livestock sector constitutes 14.5% of global green-house gas (GHG) emissions and soil water pollution due to nitrogen excretion. Methane excretions in ruminants can be mitigated by specific feeding strategies, tannins reduce methanogenesis ammonia syntheses. In our study, two kinds condensed (Mimosa Gambier) hydrolysable (Chestnut Tara) were added (4 g/100 g DM) a basal feed (barley: 48 DM,...

A total number of 60 weaned male New Zealand White rabbits at 6 weeks age with an average initial body weight 704 ± 20g were randomly divided into four groups, fifteen /each during the experimental period (May−June 2020). First group was fed basal diet without any additive as a control group, while 2nd ,3rd and 4th groups hydrolysable tannin Silvafeed® ATX (HT, 1.5 g/kg diet), grape seed extrac...
