Abstract
Two novel sesquiterpenes and one new monoterpene, together with eight reported compounds were isolated from dichloromethane–soluble extract of the aerial part of Artemisia tournefortiana Reichb. Their relative and absolute structures were elucidated based on the analysis of 1D and 2D NMR spectra, HRESIMS, and calculated electronic circular dichroism (ECD). Two sesquiterpenes (1 and 2) showed no inhibition effect in anti-inflammatory and cytotoxic activity tests. Three new terpenes (1–3) were tested for antibacterial activity, compounds 2 and 3 showed moderate antibacterial activities with minimum inhibitory concentrations (MICs) between 264 and 556 μg/ml.
