Objective: To objective of this work was to perform phytochemical qualitative and quantitative analyzes of the main secondary metabolites in the root of Berberis microphylla. Methods: The extracts of B. microphylla root were tested through phytochemical screening and the quantification of the most important constituents was carried out using spectrophotometric and gravimetric techniques. Result...

Tannins are a unique category of plant phytochemicals especially in terms of their vast potential health-benefiting properties. Researchers have described the capacity of tannins to enhance glucose uptake and inhibit adipogenesis, thus being potential drugs for the treatment of non-insulin dependent diabetes mellitus. Thus, the present research was conducted to find out tannin content of food p...

Tannins are naturally occurring protein-binding polyphenols that occur in many forage plants and which reduce nutritive value through inhibitory effects on ruminal and intestinal functions. Some animals have adapted to tannins through the synthesis of tannin-binding salivary proteins, the presence of tannin-resistant or tannin-degrading ruminal/intestinal microorganisms, or other potential adap...

Astringency is an important characteristic of red wine quality. The sensation is generally thought to be produced by the interaction of wine tannins with salivary proteins and the subsequent aggregation and precipitation of protein-tannin complexes. The importance of wine astringency for marketability has led to a wealth of research on the causes of astringency and how tannins impact the qualit...

Rhizoctonia solani Kuhn. is a fungal pathogen that causes sheath blight in rice plants. Sheath disease can reduce production for the people of Indonesia. To prevent blight, fungicides are used. The continuous use synthetic with inappropriate doses have negative impact, so it necessary to look alternatives vegetable fungicides, one which clove leaf (Syzygium aromaticum L.). aim this study was de...

Tannery wastewater is considered one of the most contaminated and problematic wastes since it consists considerable amounts organic inorganic compounds. These contaminants result in high chemical oxygen demand (COD), biochemical (BOD), total suspended solids (TSS). In this work, heterogeneous photodegradation recalcitrant COD from tanning industry was investigated, particular due to presence ve...

In order to study the effects of tannins at histomorphological level, mice were either fed with three structurally different types of tannins (tannic acid, chestnut, and quebracho) or treated with isoproterenol, during 10 days. Acini of parotid and submandibular glands increased significantly, being the increase higher for parotid compared to submandibular glands, and higher in the quebracho co...
