Phytochemical studies on Diplotaxis harra growing in Sinai

Abstract


Five main flavonoid glycosides were isolated from the ethanolic extract of Diplotaxis harra (Cruciferae), and were identified as quercetin, isorhamnetin 3-rhamnoside, isorhamnetin 3-o-rutinoside, isorhamnetin 3-glucosyl-4`-rhamnoside and isorhamnetin 3-o-β-glucoside. These compounds were identified according to their Rf values, partial and complete acid hydrolysis, UV, 1H-NMR, 13C-NMR and 2D NMR (HSQC, HMBC) spectroscopy. The alcoholic extract of plant was evaluated against some bacterial strains which showed moderate antibacterial activity, while petroleum ether extract doesn't show any activity.
