A new isoflavane, suaeglaucin A (1), which was isolated from the herb of Suaeda glauca (Bunge) Bunge, was elucidated as 5,6,8-trimethoxy-7- hydroxycoumaronochromone based on its MS and 1D and 2D NMR spectroscopic data. The structure of compound 1 was confirmed by X-ray crystallographic analysis. Five known compounds (2-6) were also isolated. All compounds were isolated for the first time from Chenopodiaceae. We found that compounds 2 and 4 possessed moderate antioxidant activity.
