Chenopodium ambrosioides (Chenopodiaceae) growing wildly in Egypt was subjected to antioxidant-guided phytochemical investigation and the EtOAc fraction afforded the two new flavone glycosides; scutellarein-7-O-α-rhamnopyranosyl-(1→2)-α-rhamnopyranosyl-(1→2)-α-rhamnopyranoside (1) and scutellarein-7-O-α-rhamnopyranosyl-(1→2)-α-rhamnopyranoside (2). In addition, the in vitro antioxidant activities of the plant alcohol extract, CHCl 3 fraction, EtOAc fraction and isolates were studied.
