Antioxidant potential of some Sudanese medicinal plants used in traditional medicine

Abstract

In the present work methanolic and water extracts of 19 medicinal plants, commonly used in Sudanese folk medicines against gastrointestinal tract, infectious diseases were investigated for their antioxidant activity. Antioxidant assays were carried out by using different in vitro models such as DPPH (2, 2-diphenyl-1picrylhydrazyl) radical scavenging and Iron chelating activity. Methanolic and water extracts of Punica granatum showed the highest total antioxidant activity of 71±0.03 and 73±0.01 respectively. The antioxidant activities of water extracts were poor when compared to the methanol extract. The iron chelating power of methanol and aqueous extracts of Commiphora myrrha 58±0.01 and Azadirachta indica 57±0.20 respectively.

Antibacterial properties of traditional Sudanese medicinal materials against selected enteric bacterial strains

“…(7) (1Z=18 mm), but moderate (1Z=14-18 mm) efficacy was observed against E.coli no. (6) (1Z=16mm)( (Elkamali and Mahjoub, 2015).…”

“…It is considered as the source of natural antioxidants. It can be used simply as possible food complement, and in pharmaceutical implementations (Elkamali and Mahjoub, 2015). B.subtilis (NCTC 8236) showed promsing (˃18 mm) degree of sensitivity (1Z =24mm) to methanolic extracts of U.molliuscula, which exhibit antibiotic-resistant to Co-Trimoxazole and Ceftizoxim; same goes to Piperacillin/Tazobactam, Chloramphenicol and Ciprofloxacin.…”
