Purpose: The volatile oil shows various biological activities like antibacterial, antifungal, anti-inflammatory, antioxidant, anticancer activity etc. The antibacterial activity of their components may be a solution to increasing antibiotic resistance of microorganisms that is due to use of commercial antimicrobial drugs. The plant Galinsoga formosa (Family- Asteraceae) contain volatile oil and used in wounds, cuts, snake bite, diabetes, vomiting, high BP, antimicrobial, blood pressure, nutritive, astringent.
Material and method: The purpose of study was to determine the antibacterial activity of volatile oil obtained from distillation using Clevenger apparatus. The gram positive bacteria Staphylococcus aureus was used as test organism, nutrient broth as culture media and ampicillin as reference antibiotic. The oil showed 1.1±0.1 mm zone of inhibition while ampicillin showed 6.1±0.12 mm zone of inhibition.
Conclusion: It was concluded that oil show antibacterial activity.
