Chemical constituents and HRESI-MS analysis of an Algerian endemic plant - batt. - extracts and their antioxidant activity.

This is the first report on the phytochemistry and antioxidant activity of ethyl acetate and - butanol extracts from an Algerian endemic plant Batt. (Scrophulariaceae). Both extracts were subjected to a phytochemical study by semi-preparative HPLC, which led to the isolation and identification of nine compounds: methyl linolenate (1), methyl linoleate (2), Phytol-1(3), Martynoside (4), Isomartynoside (5), -martynoside (6), Ilwensisaponin C (7), Ilwensisaponin B (8), Ilwensisaponin A (9).
