The agricultural processing industry usually generates a remarkable amount of by-products rich in bioactive compounds, which can be exploited for agri-food or nutraceutical applications. Pistachio’s hard shell is one the major from pistachio industrial processing. aim this work was evaluation shells as potential source natural antioxidants. We evaluated different extraction procedures by measur...

Ruminant animals raised in arid, semi-arid and mountainous regions in various parts of the world rely heavily on shrub and tree species as the main diet component. The presence of secondary compounds – mainly tannins – in a wide range of these plant species constrains their fodder potential. Tannins may cause toxicity when present in the hydrolysable (HT) form, and may reduce considerably the n...

Tannins have long been considered 'anti-nutritional' factors in monogastric nutrition, shown to reduce feed intake and palatability. However, recent studies revealed that compared with condensed tannins, hydrolysable tannins (HT) appear to have far less impact on growth performance, but may be inhibitory to the total activity of caecal bacteria. This in turn could reduce microbial synthesis of ...

The chemical composition of plant polyphenols Plantago major L. and lanceolata growing in Uzbekistan was studied. More than 20 compounds, including 7 flavonoids, 9 phenolic acids, 8 hydrolysable tannins, the ages which have been determined using physicochemical methods research isolated from plants. From P. L., along with well-known such as gallic acid, rutin, luteolin, isorhamnetin, hyperoside...

Background & Aim: Identification, characterization and detection of medicinal plants chemical composition are very important for phytochemical scientific source. Sumac is one of the medicinal plants in the world that uses for industrial and pharmacological application. In this study, chemical composition of Rhus coriaria has been investigated. Experimental:</s...

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,...

Cytinus hypocistis (L.) L. is a comestible holoparasite with great potential for cosmeceutical application. Although its high tannin content has been associated bioactive and inhibitory enzyme properties, this the first report establishing relationship between parasite host (Halimium lasianthum (Lam.) Greuter) phenolic profile properties. Thus, five extracts (aerial root of non-parasited parasi...

In the present work, we investigate how the degree of ripeness (low, low-medium, medium and medium-high) affects the physical and compositional changes, as well as antioxidant properties of pomegranate fruit (cv. Mollar de Elche). The skin, pellicle, seed and juice were analysed. The fruit mass increased and the fruit skin became reddish (higher a* and lower h*) as the fruit ripening progressed...
