Structure elucidation of a new rearranged abietane diterpene from a biologically active plant, Salvia eriophora

Abstract

A new rearranged abietane diterpenoid, eriophoroxide (1), was obtained from the root extract of Salvia eriophora Boiss. and Kotschy ex Boiss. Its structure was elucidated by spectroscopic methods and semi-empirical/ab-initio calculations. DNA damaging, cytotoxic and antioxidant activities of the plant extract were tested.
