Abstract

The aromatic herb tulsi (Ocimum spp.) is a member of the Lamiaceae family. Holy basil (Ocimum sanctum) and Mediterranean basil (Ocimum basilicum) are the two main categories into which tulsi can be divided. Three Tulsi species—Krama Tulsi (Ocimum sanctum), Krishna Tulsi (Ocimum tenuiflorum), and Mediterranean basil (Ocimum basilicum)—were compared for their phytochemical and antibacterial activity in this study. These tulsi species are distributed throughout Chhattisgarh's various agroclimatic zones. Different extractions from all three species were made for their anti-microbial efficacy against bacteria (Petroleum ether extract, Ester extract, methanol extract, chloroform extract and formaldehyde extract). The disc diffusion method and well diffusion method were the two techniques used to test for antimicrobial activity. Findings indicated that Ocimum tenuiflorum exhibited the largest zone of inhibition with petroleum ether, ester, and methanol extracts among all tulsi species and two bacterial strains..
