5 phenylpropanoid glycoside contained in Radix Scrophulariae has liver protection effect. It is found that phenylpropanoid glycoside XS-10 has obvious protective effect on hepatocyte injury caused by D-galactosamine and can inhibit hepatocyte apoptosis. Anti-liver injury cell apoptosis may be related to its regulation of hepatocyte apoptosis-related genes.

The antioxidant activity of phenylpropanoid glycosides in Radix Scrophulariae is obviously stronger than that of iridoids. Phenylpropanoid glycosides XS-8 and XS-10 have significant repair effects on hydroxyl addition free radicals of deoxynucleotides, while iridoid glycosides XS-6 and XS-7 have no obvious effect under the same conditions. It can significantly inhibit the oxidative hemolysis of red blood cells, and the former two are obviously stronger than the latter two.
