In vitro antioxidant activity of Entada pursaetha

The antioxidant activity of the crude methanolic extract of the seeds of Entada pursaetha the stem of Toddalia aculaeta and the fruit of Ziziphus mauritiana was investigated The total phenolic composition of methanolic extract was calculated to be 5 5mg catechol equivalents/g of sample Antioxidant activity of the extract was evaluated on the basis of ability of scavenging free radical and

[Effects of rutin on protective capacity in rats

The stability of lysosome membranes was estimated by the change of unsedimentable activity of lysosomal enzymes--arylsulfatase β-galactosidase and β-glucuronidase Rutin administration led to dose-dependent increase in the activity of antioxidant enzymes In rats of the 3rd group received high-rutin diet the activity of QR HO-1 PON-1 and GST increased by 68 29 17 and 22% respectively

Activity and stability studies of verbascoside a novel

18/08/2011Stability studies were performed by HPLC and a PCL assay was adopted to determine the radical scavenging activity toward superoxide anion The high hydrophilic character of verbascoside suggested in a somewhat limited range of possible applications leading us to explore its derivatization to obtain the semi-synthetic derivative VPP an acyl derivative of verbascoside with an improved range

Polymer stabilizers

Polymer degradation is a change in the properties—tensile strength color shape etc —of a polymer or polymer-based product under the influence of one or more environmental factors such as heat light or chemicals such as acids alkalis and some salts These changes are usually undesirable such as cracking and chemical disintegration of products or more rarely desirable as in
