| Abstract | ||
| It was isolated a flavonoid compound from the local group seed as red powder with maximum yield equal to (0.4gm) at room temperature. The chemical and physical properties of this compound were studied using thin layer chromatography (TLC), IR _ spectrum, UV_VIS spectrum, Melting point and qualitative test. The antibacterial activity of the flavonoid compound was determined against types of standard strains of bacteria which were Staphylococcus aureus NCTC 6571 and Escherichia coli NCTC 5933. The results indicated that the flavonoid compound has varying degrees of inhibiting the test organisms. The minimum inhibition concentration (MIC) of this compound was estimated by using filter disk assay against types of gram positive and gram negative bacteria were 2.5 and 10μg/ml respectively. | ||
