Background: Today Herbal medicine are commonly used because of their easy availability and affordability. It is more closely corresponds to the patient’s belief, concerns about the adverse effects of chemical (synthetic) medicines, persuade a desire for more personalized health care, and allows significant public access to health information. The major use of herbal medicines is for health promotion and treatment for chronic, as opposed to life-threatening, conditions. Usage of traditional remedies increases when conventional medicine is less effective in the treatment of disease, such as in advanced cancer and in the face of new infectious diseases. The hibiscus Rosa sinensis plant extract have multiple organic component like flavonoids, tannins, alkaloids, triterpenoids which are known to have antibacterial activity against E. coli, P aeruginosa, Salmonella species. Phytotherapy is considered to be less toxic and minimal or no side effects in comparison to modern allopathic medicines. Therefore, in today’s scenario there has been reappearance of interest developed in herbal medicine. Therefore, the study was planned to look for antibacterial activity of extract of petals and leaves of hibiscus Rosa sinensis against.

Methods: Escherichia coli isolated from different clinical samples along with resistant antibiotics. All resistant isolates were tested along with hibiscus Rosa sinensis extract both leaves and petals ex-tract with resistant antibiotics.

Results: We found that out of total 51, 35 (68.63%) were resistant E. coli isolates to different antibiotics and 85.72% were from urine samples. Enhancement effect in zone size with many resistant antibiotics was seen individually with both extracts. Antibiotics like ampicillin, cefotaxime, cotrimaxazole, cefuroxime, piperacillin, gentamycin showed more enhancement with rose petal extract than leaves. While antibiotic like levofloxacin (5%) showed enhancement only with leaves extract and not with the petals extract.

Conclusions: It was found that Rose petal extract showed more antibacterial activity along with the antibiotics as compare to Rose leaves extract.
