| dc.description.abstract | A study phitochemical and antibacterial essay of the methanol extract of stem bark Melochia umbellate (Houtt( Stapf vardegrabrata (Paliasa). The result of this study showed that the methanol extract from the bark of M. umbellate (Houtt) Stapf var degrabrata class of compounds containing; Steroids, flavonoids, triterpenoids, phenolics, and saponins. Methanol extract from the bark of M. umbellate can inhibit the growth of bacteria Bacillus subtilis, Staphylococcus aereus gram-negative bacteria as well as representing Escerechia coli, Salmonella typhi, and Pseudomonas aeruginosa representing gram-positive bacteria. At the concentration 400 ppm of methanol extract of these plants showed effective barrier againts bacteria tested, with a zone of inhibition, respectively as follows: 12.67 mm against bacteria B. subtilis, 12.97 mm against bacteria S. aereus, 11.86 mm against bacteria E. coli, and 12.12 mm against bacteria S. typhi. However methanol extract from the bark of M. umbellate showed no impediments ti the growth of bacteria P. aeruginosa. | en_US |
