Abstract

Nyale is a sea worm that belongs to class of polychaete. It appears on a huge crowd, usually five days after the monsoon in February, at the surface of the sea for breeding. The colors of the female and male worms are green and brown, respectively. The worms are collected in nyale season, freezed-dryer, and extracted with ethyl acetate. Antimicrobial activity properties of the male worm extract are carried out toward benthos bacteria and clinical isolate bacteria using ciprofloxacin as comparing agent. The results show that, after colom chromatography, fraction number 1 and 4 have the best antibacterial activities (broadest spectrum) toward clinical isolate bacteria. All eleven fractions show also antibacterial activities toward nine benthos bacteria. The minimum inhibitory concentration (MIC) of fractions 1 and 4 toward six clinical isolate bacteria is 100 μg/ml. Meanwhile, fraction 4 exhibits two peaks in its HPLC chromatrogram.

Abstract

Syzygium aqueum plant of the family Myrtaceae is native of Malaysia and Indonesia and is known as the water rose. The active compound is useful as an antibacterial. This study aimed to determine the effects of ethanol extracts of guava leaves (S. aqueum) as an antimicrobial against clinical isolates bacteria in vitro. The design used in experiment was a Completely Randomized Design (CRD). Data were analyzed using the Kruskal-Wallis test. Results of statistical analysis using SPSS 20 for windows indicated that the ethanol extract of guava leaves has a significant (P<0,05) effect in inhibiting the growth of clinical isolates bacteria. MIC (Minimum Inhibition Concentration) of ethanol extracts for each bacterium can not be determined because the guava leaf extract was very dark. The MBC (Minimum Bacterisidal Concentration) of ethanol extract of guava leaf  for both S. aureus and S. dysenteriae was 20%.  The MBC of the extract for E. coli, S. thypi, V. cholerae was 25%, where as for B. cereus was at concentration of 50%. It can be concluded that guava leaf has highly potential as a source of antimicrobial agent.Keywords:Antibacteria, Guava Leaf, Clinical Isolates Bacteria, Ethanol Extract
