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 ...

Matricaria pubescens is traditionally used as a postpartum antihemorrhagic and to treat digestive disorders. The aim of this study determine the total amounts phenols, flavonoids, condensed tannins, hydrolysable anthocyanins antioxidant capacity samples from different regions periods in Algeria order guide selection varieties period harvest. analysis was carried out by Ferric reducing power (FR...

Rhubarb (Rheum emodi) is an important medicinal plant, which finds an extensive use in Ayurveda and Unani system of medicine. Rhubarb (Rheum emodi, family Polygonaceae) has been traditionally used as diuretic, liver stimulant, purgative/cathartic, stomachic, Antitumour, anticholesterolaemic, antiseptic, wound healer, antidiabetic and tonic.

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 ...

This study was designed to identify and quantify the major phenolic constituents in peeled kernel pellicle of walnut Juglans regia L. Data were compared across six different cultivars: 'Fernor', 'Fernette', 'Franquette', 'Sava', 'Krka' 'Rubina'. High-performance liquid chromatography coupled with mass spectrometry used these compounds. Nineteen ellagitanins, 12 ellagic acid derivatives, 4 antho...

Food, feed and beverage processing brings tannins into contact with macromolecules, such as proteins polysaccharides, leading to different chemical physical interactions. The interactions of are well known but less is about the affinity polysaccharides. We used bacterial cellulose from nata de coco a model compound investigate how interact by adsorption measurements using UPLC-DAD. also explore...
