Abstract
Antibacterial and antifungal activity of leaf, bark, flower and seed extracts of Thespesia populnea L.was investigated. The antibacterial activity and antifungal activity was tested against both gram-positive and gram-negative bacterial organisms. Among the four kinds of explant extracts like leaf, bark, flower and seed; methanolic leaf extract exhibited broad spectrum zone of inhibition due to the more phytochemical constituents are retained in methanolic leaf explant extract of Thespesia populnea. Results inferred that gram-negative bacteria showed significant zone of inhibition activity than gram positive bacteria. All the explant extracts showed maximum activity against the fungal organisms in the order of Colletetrichum falcetum, Aspergillus niger and Mucar piritorus respectively. Zone of Inhibition was increased with increase in concentration of explants leaf, bark, flower and seed extracts of Thespesia populnea L.
