Five new bioactive compounds from Chenopodium ambrosioides.

Five new bioactive compounds, chenopodiumamines A-D (1-4) and chenopodiumoside A (5), were isolated from the ethanol extract of Chenopodium ambrosioides. The structures of these compounds were elucidated by various spectroscopic means (UV, IR, HR-ESI-MS, 1D and 2D NMR). Compounds 1-3 had moderate antioxidant and anti-inflammatory activities.
