our previous study revealed that the antioxidant activity of polysaccharide (coded as fgfp) extracted from grifola frondosa by enzymolysis treatment was significantly superior than that (coded as gfp) extracted by boiling-water. in this study, one purified polysaccharide fractions (coded as fgfp-11) was obtained from fgfp by purified using deae-52 column and sephacryl s-500hr column. results in...

this study was designed to examine the in vitro antioxidant activities and total phenolic contents of the methanolic extracts from male inflorescence of salix aegyptiaca l. grown in iran. the methanolic extract (me) and its three fractions including water (wf), butanol (bf) and chloroform (cf) were prepared and then their antioxidant activities, as well as total phenolic contents, were evaluate...

Chlorogenic acid is a well-known antioxidant and has more isomers according to the difference in binding location and number of caffeic on quinic acid. In this study, we investigated and compared the profiles of antioxidant and DNA-protective activities of chlorogenic acid isomers including three caffeoylquinic acid isomers (3-O-caffeoylquinic acid, 3-CQA; 4-O-caffeoylquinic acid, 4-CQA; and 5-...
