Ingestion of small amounts of condensed tannin (CT) by ruminants can produce valuable outcomes such as improved nitrogen use and reduced bloating, methane output, and gastrointestinal parasitism. However, many grasses and forbs contain little if any CT. The specific types of CT vary in plants and can have somewhat different effects on ruminants. Individual ruminants can respond differently to C...

This study was designed to identify some bioactive phytochemicals from ethanolic extract of roots of Litsea polyantha and to evaluate some of its pharmacological activities. Phytochemical tests indicated the presence of reducing sugar, combined reducing sugar, tannins, flavonoids, alkaloids, terpenoids, and phenol. In the antioxidant assay using 2-diphenyl-1-picryl-hydrazyl (DPPH) free radical ...

Background. We compared the efficacy of P. granatum (P) flower extract with that of silver sulfadiazine (SSD) for treating thermal burn injuries in rats. Methods. Ten Wistar rats in each group were topically given base cream, normal saline, cream containing 1% SSD, or creams containing 5% or 10% Punica granatum flower extract. The treatments were administered once daily until complete wound hea...

Recently, tannins have received considerable attention as health-promoting component in various plant foods and several studies have reported on its nutraceutical properties. However, no study has established the role of condensed tannins in indigenous foods of Kenya. Therefore, this study was designed to evaluate the antioxidant activity (DPPH and FRAP) and antidiabetic effects (α-amylase and ...

Eight brands of tea (Camellia sinensis),which are cultivated and commercially available in Ethiopian market, were analyzed for estimation of their total secondary metabolites (polyphenols, flavonoids and tannins) content and free radical scavenging activity which is expressed on dry weight basis. In this present study, the total polyphenols, tannin and flavonoid contents were studied spectropho...

this study was undertaken to evaluate the effect of hydrolysable tannin (ht) and condensed tannin (ct) on growth performance and body composition of nile tilapia. hydrolysable tannin and ct were included into diets at four levels (0, 5, 15, and 25 g kg-1 diet). the diet with zero tannin level acted as control and the response of fish fed diets containing tannin was compared to that of the contr...

Phytochemical analysis of the ethanolic extract leaves Cucurbita maxima indicated presence reducing sugars, alkaloids, saponins, tannin, steroid and glycosides whereas Euphorbia royleana glycosides, steroids tannin. The possible analgesic anti-oxidant activities were investigated. exhibited inhibition writhing reflex 16.13% 41.94% respectively (P<0.001 P<0.001) 19.35% 45.16% (P<0.02 on...
