Abstract
One new ionone glycoside, named centrantheroside F (1), together with 9 known compounds (2-10), were isolated from the roots of Centranthera grandiflora. Their structures were determined by spectroscopic data analyses and comparing with the literature data. The absolute configuration of 1 was confirmed via 2 D NMR and electronic circular dichroism (ECD). All isolated compounds were evaluated for their inhibitory activity on lipopolysaccharide (LPS)-induced nitric oxide (NO) production.
