Spectral scanning was used to provide estimates of the leakage of the cyanogenic glucoside, dhurrin (p-hydroxy-[S]-mandelonitrile-beta-d-glucoside), and its metabolite, p-hydroxybenzaldehyde (p-HB), from young light-grown shoots of Atlas sorghum (Sorghum bicolor [L.] Moench) when these shoots were immersed in water, toluene, chloroform or mixtures of water and toluene or water and chloroform. M...

In recent years, Old Yellow Enzymes (OYEs) and their homologues have found broad application in the efficient asymmetric hydrogenation of activated C=C bonds with high selectivities and yields. Members of this class of enzymes have been found in many different organisms and are rather diverse on the sequence level, with pairwise identities as low as 20 %, but they exhibit significant structural...

After far-infrared (FIR) radiation onto rice hull, a methanolic extract was prepared for the determination of antioxidant ability. After 30 min of FIR treatment, the radical scavenging activity and total phenol contents of rice hull extracts increased from 47.74 to 79.63% and from 0.12 to 0.19 mM, respectively, compared to control. Inhibition of lipid peroxidation in extracts was also increased...

The roots of Potentilla fulgens have been used for a long time as a folk remedy for many ailments without having information on its pharmacological action. Of the various extracts prepared by partitioning of the methanol extract, the ethyl acetate fraction was found to possess better antioxidant and cytotoxic activities. The degree of reduction in cloning efficiencies of MCF-7 cell lines was mo...
