Pomegranate (Punica granatum) peel is a nutritive, antioxidant rich byproduct, easily available after production of pomegranate juice and ready to eat arils. The present study is undertaken to know the nutritional importance of fresh and detanninated pomegranate peel powder. Fresh pomegranate peel collected after juice extraction from Bhagwa variety of pomegranate. Fresh peels were crushed fine...

In context with the frequent observations of excessive iron (Fe) storage in captive black rhinoceroses (Diceros bicornis), it has been suggested that both an excessive dietary Fe content and a lack of dietary Fe-chelating substances, such as tannins, is the underlying cause. Therefore, studies on the effects of tannin supplementation to captive diet are warranted. Six captive rhinoceroses were ...

Vascular endothelial growth factor A (VEGFA) plays an important role in tumour angiogenesis and its angiogenic action is mainly mediated through its VEGF receptor 2 (VEGFR-2). Therefore drugs targeting VEGFA/VEGFR-2 are being presently used in the clinics for treatment of several types of solid malignant tumours. We here in report that low dose of chebulagic acid (CA), a hydrolysable tannin fou...

The aim of this work was the synthesis of silver nanoparticles using two types of tannins, hydrolysable and condensed, and comparing the properties of incurred colloids. Both tannins are powerful antioxidants (reductants) which differ in their chemical structure as well as certain properties, which influences the formation of silver particles as well as the composition and properties of the res...

the effect of grape pomace (vitis vinifera) and in oak leaf (quercus libani) tannins by three runs of in vitro gas production on the organic matter digestibility (omd) and in situ dry matter (dm) and crude protein (cp) disappearance were studied in four sheeps. polyethylene glycol (peg) was used to deactivate the tannins. in vitro gas production was recorded at 2, 4, 6, 8, 12, 48, 72, 96 and 12...

Seeds collected from trees, shrubs and lianas growing on Barro Colorado Island, Panama, were analyzed for their content of phenolic compounds, oxidative activities protein precipitation capacities. Proanthocyanidins hydrolysable tannins detected in one-third 189 studied species. The most oxidatively active group species the ones containing prodelphinidins ellagitannins whereas that had highest ...

Fresh fruits are rich sources of polyphenolic compounds. The polyphenolics present in plant sources are known to have beneficial effects, especially in the prevention of cardio-vascular diseases, cancer, etc. Therefore, the consumption of fresh fruits is not only associated with vitamin supplementation, but also serves as an effective preventive agent for many diseases. The polyphenolic compoun...

Forest tree leaves (12 different species) of semi hilly arid region of Punjab State were collected at 30-day interval throughout the year to assess the seasonal variations in tannin profile. Tannins were extracted and fractionated from fat free samples and data were analyzed statistically by 12×12 factorial design. The leaves of Anogeissus latifolia had the highest (p<0.05) concentration of tot...

Tannins are a group of polyphenolic compounds synthesized and accumulated by higher plants as secondary metabolites. They divided into hydrolysable tannins proanthocyanidins found in many plant tissues which they occur diverse structures amounts. This review provides brief background on tannin distribution plants, summarizes the current literature strawberries, raspberries, blueberries, current...
