Phenylpropanoid dimers from Chrysanthemum indicum with antioxidant effects via activating the Nrf2 signaling pathway.

Five phenylpropanoid dimers chrysanthephenyls A-E, with the 1-O-1'-type (1) and 1-O-2'-type (2-5) ether bond linking modes, were isolated from the aerial parts of Chrysanthemum indicum. Among them, chrysanthephenyls D and E were two pairs of enantiomers, and chrysanthephenyl E was further resolved into its enantiomers (+)-chrysanthephenyl E and (-)-chrysanthephenyl E via chiral-phase HPLC. Their structures were characterized on the basic analysis of the spectroscopic techniques (IR, HRESIMS, 1D and 2D NMR), and their absolute configurations were determined by DP4+ NMR analysis and ECD calculation method.

Effects of salt ions and pH on deamidated soybean protein hydrogels formation: Molecular structure, thermal aggregation and network.

The aim of this study was to explore the effects of environmental factors (salt ions and pH) on the thermal gelation process of deamidated soy protein isolate (DSPI). The results indicated that with increasing salt ion concentration, DSPI assembled into larger aggregates, which were more prone to aggregation in thermal reactions, ultimately forming a gel network with higher viscoelasticity. The strength enhancement of ion-induced gel networks followed the order from highest to lowest: Ca > Mg > Na.
