Two New Flavone Glycosides from Chenopodiumambrosioides Growing Wildly in Egypt

Chenopodiumambrosioides (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 scutella-rein-7-O-α-rhamnopyranosyl-(1→2)-α-rhamnopyranoside (2). In addition, the invitro antioxidant activities of the plant alcohol extract, CHCl 3 fraction, EtOAc fraction and isolates were studied.
