Abstract
One new aryldihydronaphthalene-type lignan (1) together with eight known lignans (2-4, 7–11) as well as two caffeic-acid dimers (5, 6) were isolated from an ethanol extract of the whole plant of Corispermum mongolicum Iljin (Chenopodiaceae). The chemical structures of these compounds were determined from 1D and 2D NMR and HR-ESI-MS spectra, and results were compared with data from the literature. This study is the first demonstration of nine compounds (2 and 4–11) isolated from the Chenopodiaceae family, with one of these (3) from the genus Corispermum. Anti-inflammatory effects of the isolated compounds were evaluated in terms of inhibition of production of nitric oxide, tumour necrosis factor-α, and interleukin-6 in lipopolysaccharide-induced RAW 264.7 cells.
