Antibacterial activity of two water plants Nymphaea alba and Salvinia natans leaves against pathogenic bacteria


Author(s): Ghazi Malih Al-Maliki, Khaled Kh Al-Khafaji and Rafid M Karim

Abstract: The present study was carried out to evaluate the antibacterial activity of two water plants Nymphaea alba and Salvinia natans leaves against three pathogenic bacteria Escherichia coli, Vibrio sp. and Staphylococcus aureus collected from branches connected to Shatt Al-Arab river in Al-Qurna city. The whole plant extracts from ethanol and Acetone were tested for their activity against pathogenic bacteria (E. coli, Vibrio sp. and S. aureus). The zone of inhibition produced by different extracts against the test bacteria was measured and compared with standard antibiotic disc. The extracts obtained from ethanol, Acetone showed higher inhibition zones of 26.2 mm and 18.8 mm, respectively against Vibrio sp. Minimum inhibition concentration values of Acetone extracts were demonstrated at low concentration ranging from 20.0 mg/mL up to 160.0 mg/mL compared to ethanol extracts which were observed ranging from 10.0 mg/ mL up to 80.0 mg/mL.
