Thunbergia is a genus of flowering plants that belongs to the family Acanthaceae and includes around 100 species distributed in the tropical region. Though many studies have been carried out in identifying various active biochemical compounds in different species of Thunbergia, a comparative analysis of the four species vizT.alata, T.erecta, T.grandiflora var blue and white and T.fragrans is a novel attempt in terms of its antimicrobial activities as well as phytochemical screening. From the present study it is clear that T.erecta T. elata and T.grandiflora contains rich quantity of secondary metabolities in it. The least value for flavonoids phenols and alkaloids were exhibited by T.fragrans. The antibacterial activity of the species reveals that T.grandiflora and T.fragrans possess high antimicrobial activities. The zones of inhibition in all the species were higher than that of the streptomycin standard against Streptococcus aureus. The presence of active phytochemical compounds and exhibition of antibacterial activities in these species corresponds to its pharmaceutical applications.
