In an effort to find an alternative drug for skin infections, isolation of Rhodomyrtone, antibacterial active substances was carried out from the dried leaves of Rhodomyrtus tomentosa (Ait.) Hassk. Rhodomyrtone was isolated as yellowish white needle crystals with melting range 181-183ºC. This compound was elucidated based on spectroscopic data and comparison was done with literature data. Rhodomyrtone inhibited the growth of Staphylococcus aureus ATCC 6538 and Staphylococcus epidermidis ATCC 12228 by 18.15 mm and 18.0 mm at a concentration of 1000 ppm respectively. The ability of healing skin infection was determined on rhodomyrtone vanishing cream (2% w/v). This cream was subjected to rabbit skin which had been infected with Staphylococcus aureus. Chloramphenicol cream (2% w/v) was used for standard. Edema and eritema in the area of infection were also used as observed parameters. In vivo experiments showed that rhodomytrone cream could reduce infections on rabbit skin. This preparation did not cause irritation both in rabbits and humans.
