title: Further isolation of antioxidative (+)-1-hydroxypinoresinol-1-O-beta-D-glucoside from the rhizome of Salvia miltiorrhiza that acts on peroxynitrite, total ROS and 1,1-diphenyl-2-picrylhydrazyl radical.
abstract: A furanofuranoid lignan glycoside, with radical scavenging on peroxynitrite, total reactive oxygen species (ROS) and 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical, was isolated from the rhizome of Salvia miltiorrhiza and characterized as (+)-1-hydroxypinoresinol-1-O-beta-D-glucoside based on spectroscopic evidence. The compound exhibited peroxynitrite, total ROS and DPPH radical scavenging activities with IC50 values of 3.23 +/- 0.04, 2.26 +/- 0.07 and 32.3 +/- 0.13 microM, respectively. Penicillamine, Trolox (6-hydroxy-2,5,7,8-tetramethylchroman-2-carboxylic acid) and L-ascorbic acid, acting as positive controls, showed radical scavenging activities with IC50 values of 6.72 +/- 0.25, 1.43 +/- 0.04 and 11.4 +/- 0.07 microM, respectively.
