Clerodendron inerme is used for the treatment for many diseases such as dysentery, heart diseases, AIDS, cancers, and others. Aim of this research was to determine the antibacterial and antioxidant activities the leaf alkaloids of Clerodendron inerme. To evaluate the antibacterial effects, Well diffusion assay, minimum inhibitory concentration and the minimum bactericidal concentration were used to test antibacterial activity against Staphylococcus aureus, Escherichia coli, Klebsiella pneumonia and Pseudomonas aeruginosa.For antioxidant activity, DPPH radical scavenging activity assay was used a standard method. GC-MS analysis was used to identify alkaloids. Alkaloid component from the leaves of C. inerme exhibited significant inhibition zones on the tested bacteria including P.aeruginosa. Alkaloid extracted from the leaves of the plant has high antioxidant activity compared to the control (Ascorbic acid).GC-MS resultsidentified. 1-Methylspermidine, Spermidine hydrochloride, sym-Homo Spermidine-d, Trihydrochloride, spermine, 6-Methyl-2-phenyl-quinoline, indeno[1,2- b]quinolizine, 1-Methyl-1H-indole-2-carboxylic acid, 1H-Indole-3-carboxylic acid, 2,6-Octadiene-1,8-diamine and 2-phenylindol-3-one. It can be concluded that the alkaloids of the leaves of the plant have a good antibacterial and antioxidant properties.The results indicate that the alkaloids appear in C. inerme leaves can be a new source of antimicrobialsagents against pathogenic bacteria and antioxidant sources.
