TROSZYŃSKA A., CISKA E. (2002): Phenolic compounds of seed coats of white and coloured varieties of pea (Pisum sativum L.) and their total antioxidant activity. Czech J. Food Sci., 20: 15–22. The purpose of this study was to compare the composition and contents of phenolic acids and condensed tannin in the seed coats of white and coloured varieties of pea and to examine the antioxidant properti...

The present study deals with the pharmacognostical studies on Morinda tinctoria.(Roxb). The leaves of M.tinctoria were shade dried and mechanically powdered after keeping them in an oven at 35oC for 24 hours. These powdered materials were used for further physiochemical, phytochemical and fluorescent analysis. The leaves contains total ash value is 31%, acid insoluble ash and acid soluble ash v...

this study was carried out to investigate the effects of treated protein supplements with tannin extracted from pistachio by-product (p-pb) on in vitro gas production using fistulated sheep. one portion of p-pb was mixed with four portions of water for 48 h. the extracted product was sprayed on soybean meal (sbm) or canola meal (cm) with an equal ratio (1:1 v/w) and dried in the shade. the expe...

Cotton dusts contain condensed tannins and endotoxins, which are suspected of contributing to the development of acute and chronic biological responses in some cotton textile mill workers. Condensed tannin extracted from cotton dust was coated on to cellulose powder, and the tannin coated powder was treated with an alkali solvent system previously developed to reduce the endotoxin content and p...

A toxicity test is a to detect the toxic effect of substance on biological system and obtain typical dose-response data from preparation. This study aims determine content secondary metabolites aqueous extract ethanolic gardenia leaves, characterization leaf extract, acute using BSLT method against Artemia salina Leach shrimp larvae.Phytochemical screening tests were carried out by color change...

The invasive shrub, Acacia longifolia, native to southeastern Australia, has a negative impact on vegetation and ecosystem functioning in Portuguese dune ecosystems. In order to spectrally discriminate A. longifolia from other non-native and native species, we developed a classification model based on leaf reflectance spectra (350–2500 nm) and condensed leaf tannin content. High variation of le...

BACKGROUND OF THE STUDY As a widely used traditional medicine, Galla Chinensis is rich in tannins. However, there are few detailed studies about pharmaceutical preparations of Galla Chinensis tannin extract (GTE). In the present experiments, for better application and to investigate the possibility that Galla Chinensis tannin extract can be used as an antidiarrheal drug, we prepared Galla Chine...

The objective of the present study was to investigate the anticancer activity of Chinese medicine Caulis Spatholobi extract on multicentric osteosarcoma cells. Ultraviolet spectrophotometry was used to determine the total flavonoid content in each sample; vanillin sulphuric acid assay was used to determine the condensed tannin content in each sample; and the varying degrees of inhibitory activi...

(Sorghum Bicolor (L.) Moench) on in vitro starch digestibility and α-amylase activity Authors: N.L. Mkandawire, R.C. Kaufman, S.R. Bean, C.L. Weller, D.S. Jackson, D.J. Rose Submitted to: Journal of Agricultural & Food Chemistry Recently, the effects of sorghum tannins on starch digestibility in humans have been of interest, since tanins may inhibit starch digestion and contribute to reducing g...
