Abstract

Rhaponticum carthamoides plants ("maral root") are widely used in Siberian folk medicine. The present study reports for the first time the presence of pentacyclic terpenoid, α-amyrin, in methanol extract from leaves of this plant. α-Amyrin induced proliferation of human keratinocytes (HaCaT) by about 18% while other extract components were ineffective. A panel of biochemical and cell-based assays testing the antioxidative and cytoprotective activites of α-amyrin indicated no antioxidative activity of this compound. α-Amyrin did not protect HaCaT cells against the damage caused by UVB radiation.
