Abstract:
A new phenolic amide, dihydro-N-caffeoyltyramine (1) was isolated from the root bark of Lycium chinense Miller, along with known compounds, trans-N-caffeoyltyramine (2), cis-N-caffeoyltyramine (3), and lyoniresinol 3alpha-O-beta-D-glucopyranoside (4). Their structures were determined by spectroscopic analysis. A NBT superoxide scavenging assay revealed that three phenolic amides showed potent antioxidative activity.
