Abstract

Tobacco plays an important role in international trade as one of the export commodities. Indonesia is one of the good quality export contributors of tobacco leaves in the world. Nevertheless, tobacco is used only as a raw material for the cigarette industries, and the rise on anti-cigarette regulations prompted the exploration of alternative product from tobacco plants. The content of alkaloids, flavonoids, terpenoids and steroids in tobacco leaves were reported in literatures as antibacterial. Therefore, this study proposed in vitro assay of the ethanolic heat reflux extract (EHRE) of Nicotiana tabacum var. Virginia against nosocomial bacteria pathogen ((Pseudomonas aeruginosa (ATCC 27853), Eschericia coli (ATCC 25922), Staphylococcus aureus (ATCC 25923), Enterococcus faecalis (ATCC 29212)). Kirby-bauer diffusion method was used for this assay. The concentration of the EHRE for Kirby-bauer assay were 20; 40; 60; 80; and 100%. The presence of clear zones on Kirby-bauer test, against the growth of each nosocomial bacteria pathogen show that tobacco extract has antibacterial effect. Statistical analysis result showed that each extract concentration had significant difference value (p <0,05). This study indicated that the content (alkaloids, flavonoids, terpenoids and steroids) of tobacco leaf extracts (N. tabacum) has potential as antibacterial against nosocomial bacteria pathogen. Nevertheless, optimization of tobacco leaf extract to obtain maximum active ingredient still needs to be done. This study is important for further development of the tobacco leaf extract as antibacterial
